Thank you for taking the time to read this. I am trying to complete a Lab for one of my classes and I am having an issues creating a new Metasploitable VM. I introduced an error when editing a file in the last one and had to delete it.
I am using a VMDK, obtained from SourceForge. The first machine installed with no issues. When trying to create a second machine I continually get "Can't overwrite medium..." comment when finishing the set-up.
So far I have tried:
Checking the destination folder for any existing files and folders (hidden too).
Redownloading Metasploitable
Assigning a new name to the VM, using different specs, etc.
Restarting my PC.
What I don't understand is that the error is stating, if I am not mistaken, that it is trying to overwrite the VMDK in my downloads file... when I am trying to save it in c:\Users\natsu\VirtualBox VMs. I have triple checked all fields before running the installer. I do not understand why this is happening, considering the first Metasploitable machine I had installed with absolutely no issues.

I've had this issue twice now, just randomly happened.
When I try to view the Ammps 'Home' Dashboard I get the following error:-
The file /Applications/AMPPS/ampps/softaculous/includes/enduser.php is
corrupted.
I had to re-install to fix this last time but since then (a few days ago) this has happened again?
Anybody know why this is happening and how to fix it?
I am using Version: 3.8
Update
I've done another clean install (backed up www and all the databases beforehand). I noticed there isn't even the directory /Applications/AMPPS/ampps/softaculous/includes/.
Seems to be another effected file as well:
/Applications/AMPPS/ampps/softaculous/includes/main/functions.php is
corrupted.
Upon opening these files, it appears a massively long string of characters as been added after the closing PHP tag. Deleting this string had no effect, the same errors persist.
Anyway, I've uploaded the files of Ampps for Mac which you can download here:
https://drive.google.com/file/d/18nA-ldR5BamLLqnEU0nC4Gx-PmzWSwt0/view?usp=sharing
Going to see if I can get it back working once I merge the files together (except the www folder)
Update 2:
You can now download Ampps 3.9 from their official website:
https://ampps.com/download
1.+ don't forget to save database (/var) and domains information (/ampps/data/domains) before replacing files
Doing a clean install of Ampps 3.8 will rectify the problem which is what I had to do. Frustratingly, some people including myself have experienced the issue coming back after a few days. Until there is a permanent fix for this either by an update/patch from Softaculous, a way to rectify this without having to reinstall Ampps is by doing the following:-
Take a backup of your /Applications/AMPPS/www directory
Download the Mac files from a clean installation here;
https://drive.google.com/file/d/18nA-ldR5BamLLqnEU0nC4Gx-PmzWSwt0/view?usp=sharing
Replace the existing Ampps directory with the files from the
download link
Move your /www/ folder back to the same location
You should then be able to access the Home dashboard and everything should work as normal.
As Nika mentioned, don't forget to save database (/var) and domains information (/ampps/data/domains) before replacing files (/www)
Edit 1:
Seems my version of Ampps 3.8 got updated to 3.9, I've not had any issues since this has happened.
Please create a backup first!
Shutdown AMPPS. I have fixed mine locally by replacing the enduser.php with the one from here https://files.ampps.com/5.3.2.zip.
Then after that I have replaced all the IonCube loaders with the ones you can download from here: https://www.ioncube.com/loaders.php. Source and how-to: https://www.softaculous.com/board/index.php?tid=13497&title=Ioncube_Loader_Error
Start AMPPS.
To check if you need to replace another corrupt file check error_log in your logs folder.
Steps to reproduce are very easy.
Create a Dockerfile.
My Dockerfile has many more lines, but I have trimmed them so we can focus in the source of the problem.
Said that, these two lines alone (without anything more) show the problem.
FROM microsoft/iis
SHELL ["powershell", "-Command", "$ErrorActionPreference = 'Stop'; $ProgressPreference = 'SilentlyContinue'; $VerbosePreference = 'Continue'; "]
Run docker build . and you get hcsshim::PrepareLayer - failed failed in Win32: Función incorrecta. (0x1).
Windows 10 Pro 1909 (but it happened too in 1903)
Docker version: 2.1.0.5
Engine: 19.03.5
Machine: 0.16.2
I have found the solution to the problem.
Reading all the https://github.com/docker/for-win/issues/3884 bug, some have found a simple solution: rename C:\windows\system32\driver\cbfsconnect2017.sys so it isn't loaded the next boot.
Disabling that driver enables me to do a docker build for the first time in windows containers in almost a year.
In my case Box Sync was the one using that driver.
EDIT: #GustavoTM have found that pCloud raises the same problem.
EDIT2: #VonC have noticed that some people in the issue in GitHub has solved it deleting this other file: C:\Windows\System32\drivers\cbfs6.sys. I haven't tried that, but i put it if it helps others.
The good thing is that I don't need to uninstall Box, but only rename that file.
This is still an issue (still open) with Win10.
Looks like uninstalling cloud storage providers with file system filters like Dropbox, Box, etc. as a workaround is an option for some users.
Deinstall cloud storage providers or virus scanners; if you identify which one is not working please share in https://github.com/docker/for-win/issues/3884
In my case was the problem similar but the file cbfs6.sys was placed somewhere in the rest of uninstalled application Jungle disk, somewhere in the folder c:\Program files\Jungle disk .... It's part of Callback File System signed by EldoS Corporation.
The folder could be rename only and not delete directly. So I could delete its immediately after the PC restart, before running the Docker. So it could be delete during the Docker service restart too.
It seems that I've run out of room on my Master node and I need to clear some space in order to reboot my daily tests. Selenium.log is taking up a lot of space and I'm convinced its not currently being used. Would it be safe to delete?
Edit: I deleted the file and upon starting a new build Selenium created a new log file. I didn't experience any issues during this new build either.
You don't say what creates the file, or where it is, but assuming that you can already see the important details from each build in the Jenkins UI (e.g. in the console log, or in test results etc.), then you shouldn't need to keep any files that are sitting in the workspace or elsewhere.
I can't seem to ssh into any instances that are created from a snapshot of an openSUSE instance that's created within Google Cloud (ie: not from a snapshot created locally and then uploaded). I've tested this with three different openSUSE instances, 2 that I had been working on and one that I created only to test this on, and none have been able to produce snapshots that produce instances that allow ssh. To be clear, the instances created from the snapshots start up perfectly fine and show no issues from the console, but neither the console's built in ssh nor any other ssh client (putty, mobaxterm) gets anything more than a time out error. I have successfully created instances from both a Windows and Debian snapshots that I have created myself, so I'm confident it's an issue with the specific OS.
Steps to reproduce:
Create an instance based off of the openSUSE image
Create a snapshot based off of the instance you just created
Create an instance based off of the snapshot you just created
Attempt, and fail, to connect to the instance via ssh
Any help with this would be much appreciated, and thank you very much in advance.
I was able to reproduce your issue. I'll report it to Google. If your run the command
gcloud compute instances get-serial-port-output <your-new-instance>
You will notice that there's an error indicating that couldn't find the disk.
SUSE has fixed the issue yesterday on SLES distros. The following new images are now available (bug-exempt):
sles-11-sp3-v20150310
sles-12-v20150310
We are still working on a fix to openSUSE, and we still don't have a fix for existing instances.
A procedure to address running instances has been posted:
https://forums.suse.com/showthread.php?6142-Image-from-snapshot-will-not-boot&p=26957#post26957
The above post contains all the details, the procedure below addresses the question about "what to do with running instances."
SUSE Linux Enterprise Server 11 SP3 (sles-11-sp3)
1.) Edit /etc/sysconfig/bootloader
In the "DEFAULT_APPEND" assignment replace "root=/dev/disk/by-id.." with "root=/dev/sda1". Reform the same substitution for the "FAILSAFE_APPEND" assignment.
Add NON_PERSISTENT_DEVICE_NAMES=1 to the end of the line, after "quiet"
2.) Edit /etc/fstab
Replace "/dev/disk/by-id..." with "/dev/sda1"
3.) Edit /boot/menu.lst
Replace "root=/dev/disk/by-id.." with "root=/dev/sda1" and "disk=/dev/disk/by-id/..." with "disk=/dev/sda" in both options.
Add NON_PERSISTENT_DEVICE_NAMES=1 to the end of the line starting with "kernel"
4.) Reboot the instance
5.) Execute mkinitrd
6.) Edit /etc/udev/rules.d/70-persistent-net.rules (if it exists)
Remove the mac address condition, "ATTR{address}==.....", from the rules.
SUSE Linux Enterprise Server 12 (sles-12)
1.) Edit /etc/sysconfig/bootloader
In the "DEFAULT_APPEND" assignment replace "root=/dev/disk/by-id.." with "root=/dev/sda1" and "disk=/dev/disk/by-id/..." with "disk=/dev/sda". Perform the same substitution for the "FAILSAFE_APPEND" assignment.
Add NON_PERSISTENT_DEVICE_NAMES=1 to the end of the line, after "quiet"
2.) Edit /etc/fstab
Replace "/dev/disk/by-id..." with "/dev/sda1"
3.) Edit /etc/default/grub
In the "GRUB_CMDLINE_LINUX_DEFAULT" assignment replace "root=/dev/disk/by-id.." with "root=/dev/sda1" and "disk=/dev/disk/by-id/..." with "disk=/dev/sda".
Add NON_PERSISTENT_DEVICE_NAMES=1 to the end of the line, after "quiet"
4.) Create a new grub configuration (SLES 12)
export GRUB_DISABLE_LINUX_UUID=true
grub2-mkconfig > /boot/grub2/grub.cfg
5.) Execute mkinitrd
6.) Edit /etc/udev/rules.d/70-persistent-net.rules (if it exists)
Remove the mac address condition, "ATTR{address}==.....", from the rules.
A new openSUSE 13.2 image has been published that addresses the issue as well. New instances started from opensuse-13-2-v20150315 will work with no issues with the snapshot feature in GCE. For running instances use the process outlined for SUSE Linux Enterprise 12, that should work. I did not test the procedure on openSUSE.
I am using Oracle Virtual Box version 4.2.16 r86992. Everything was fine until yesterday shutdown.
Today, it shows inaccessible and throws this error:
Runtime error opening C:\Users\xxxxxx\VirtualBox VMs\vBoxxxxXubuntu_Beta\vBoxxxxXubuntu_Beta.vbox for reading: -102 (File not found.).
D:\tinderbox\win-4.2\src\VBox\Main\src-server\MachineImpl.cpp[725] (long __cdecl Machine::registeredInit(void)).
It's good to restore this to working, It would save lot of time and restore configuration settings and data. Thanking your support.
This normally happens if the host OS crashes or you pull the plug on it, leaving the .vbox file unsaved.
In the location:
C:\Users\xxxxxxx\VirtualBox VMs\vBoxxxxXubuntu_Beta\
you should find two files:
vBoxxxxXubuntu_Beta.vbox-prev
vBoxxxxXubuntu_Beta.vbox-tmp
Copy vBoxxxxXubuntu_Beta.vbox-prev to vBoxxxxXubuntu_Beta.vbox.
Select vBoxxxxXubuntu_Beta.vbox, in the VBox manager, right click, and then left click on refresh.
Observe that it now shows Powered Off.
Now you are good to go.
Based on my experience, I was on Windows 7 and running Ubuntu 14.04 as guest OS on Virtual Machine.
Go to your Virtualbox folder (in my case):
C:\Users\Dev12\VirtualBox VMs\Ubuntu
You'll see files with extensions: Ubuntu.vbox-tmp or Ubuntu.vbox-prev
Remove -tmp from file name Ubuntu.vbox-tmp so that it reads as Ubuntu.vbox
Exit from Virtual Machine and start it again.
You should now see error gone away.
The virtual box files with extension .vbox contain metadata the virtualbox hypervisor requires to resolve the guest virtual OS' configuration.
If the main .vbox file is corrupted (i.e. reporting that it is empty) then use the backup .vbox-prev file to recover the contents of the original file.
Do this by renaming the empty .vbox files a temporary name (e.g. rename originalVM.vbox to originalVM-empty.vbox).
Then make a copy of the backup file originalVM.vbox-prev, where the copy will have the same name as the original but with the word "copy" appended to it (i.e. originalVM.vbox-prev is renamed to originalVM (copy).vbox-prev).
It is important to retain the original backup .vbox-prev file it should not be altered or itself renamed.
Now go rename the copy of the newly created .vbox-prev file originalVM (copy).vbox-prev to the original name of the empty .vbox file and be mindful to also change it extension from .vbox-prev back to just .vbox.
That is rename originalVM (copy).vbox-prev back to originalVM.vbox. Now that this is done you may add the .vbox file (guest os) back into the VBOX hypervisor. This will recover the state and snapshot of the "inaccessible" guest VM. Now delete the original empty .vbox file.
I've faced the same issue using CentOs 6.8 on a VirtualBox 5.1 installed in Windows 7 and AjayKumarBasuthkar's solution worked perfectly for me:
I went to C:\Users\\VirtualBox VMs\CentOS6.8
Made a copy of the file CentOS6.8.vbox-prev and gave it the name of CentOS6.8.vbox
Went to the VirtualBox GUI, right-clicked the VM instance and hit refresh
The CentOS instance went from the State Inaccessible to Powered Off
VirtualBox 4.3 is released and could it be that you've updated or there was some issues while updating?
In any case if you are not able to bring up the Virtualbox, remember to backup the VirutalBox VMs folder and going for a fresh install should be the best way forward.
I faced the same problem and I resolved by doing following in Oracle Virtual box 4.3.28 with Ubuntu 14.04 LTS, when Virtual box VM was closed.
Removed ubuntu.vbox to another folder outside virtual box folder
removed -prev from file ubuntu.vbox-prev
start oracle virtualbox, it works excellent.
On a Windows 7 Host, I found that Daemon Tools service had a hold on the file.
The solution was to uninstall Daemon Tools, but I suspect if you stop the service and remove the file association, you would be sorted.
The other issue might be that if your Virtual Machine was on an external hard drive, it is possible that the drive letter has changed. If so, go to Computer Management, and select the hard drive and right click to change the drive letter and save (Note that this is for Windows).
This is going to sound stupid but try to reinstall VB. It may work.
I am adding one critical and important comment to the previous great answers. Make sure that the original .vbox file is corrupted and empty before you copy the content from the.vbox-prev file. If it is not the case and you find it with lines and readable content, don't replace the content of the .vbox.
Changes made to the VM directly before the VM got inaccessible might not be updated in the .vbox-prev backup file . The changes could not be synced with those changes before the OS upgrade or system changes that led to the inaccesable issue.
If you find your VM not accessible after an OS upgrade or system change, first check the.vbox file if it is still readable by a text editor and it has lines. Then you just need to delete the VM from the VirtualBox manager list(just remove the appliance from the list and don't remove files) . Then reopen the.vbox file and it should work perfectly.
If the original.vbox file is corrupted or empty when you open it with a text editor, then and only then, you can copy the content from the .vbox-prev and follow the instructions highlighted.
This was my experience, and I wanted to share it with you to avoid losing some last minute changes before the OS upgrade or crash.
