When updating raspbian on my PI3 some package failed and after that, reboot failed.
The green led doesn't even give a "blink" and nothing on the screen.
So I think I have to reinstall it. But then the whole card will be formatted.
As I have some measurements on the card I want to know if there is a way to restore the database on a new installation.
The card seems ok as I can read all files on it. I just have to copy /var/lib/influxdb to another computer.
But is it then possible to restore the data to a new installation?
Well, I solved it.
I copied the influx directory (recursively)to another computer.
I installed a new OS on my PI3.
I copied the directory, again recursively, to /var/lib/on the new OS.
I Installed influxdb and started InfluxDB. Voila! The data was there!
Happy I am.
Thank's for watching!

Ok so I want to get a virtual machine with Windows so I can download applications only on Windows (Not on OSX (I'm on Big Sur 11.2.3 by the way)), so I downloaded VirtualBox, then downloaded the Windows thing which apparently I have to (as seen in one of the pics) (you can tell I have hardly any experience with vms), then I created a new vm in the VirtualBox app, and left all the default settings except for the type of hard drive (which is also in one of the pictures), then I clicked Start and it asked me to add a 'virtual optical disk file', so I clicked on the folder button then clicked add in the top left, and it gave me this error code:
Failed to open a session for the virtual machine w10.
The VM session was aborted.
Result Code: NS_ERROR_FAILURE (0x80004005)
Component: SessionMachine
Interface: ISession {c0447716-ff5a-4795-b57a-ecd5fffa18a4}
as you can also see in one of the pictures below. Also, when I leave the screen for a couple of minutes right before I click on the previously mentioned add button, this appears:
but I tried just leaving it to load, and nothing happened. I have tried uninstalling using the uninstall tool twice, rebooting my Mac, etc etc, and yes I have allowed everything I need to in the Security settings. I'm not installing it on a moderator account, but the Windows 10 virtual optical disk file is in Documents which the account I'm on has read and write access to, and obviously the actual VM is in applications.
Thanks so much!
Here's the previously mentioned image of the one changed setting:
And here's the pic of the Win10 64-bit I had to install:
thanks everyone!
VirtualBox Version: 6.1.22 r144080 (Qt5.6.3)
Host Operating System: MacOS BigSur
I came across exactly same issue, where clicking on add to choose image was crashing the dialog. This issue persists in the latest version of Virtual Box for Mac.
I could figure out couple of ways to avoid clicking on Add button to choose image.
First Option:
Steps:
Click on Settings to open settings window for your VM.
Choose Storage
Select Empty disc and choose Disk image by clicking small disc icon in the Attributes section. Please follow the image to have visual instructions.
Second Option:
Steps:
Click on VM's Normal start
Once you get the option to choose image, simply cancel the dialog.
Now click on the small disc icon in the bottom of VM's dialog to choose the image.
Hope this helps. Feel free to comment if you find this post useful.
I had the same message because of permissions at directories where the hard disks were stored in. So, just execute VirtualBox 'As Administrator' and all run well.
I was getting the same error on Ubuntu 22.04 machine while trying to start an existing or a new VM-
Failed to open a session for the virtual machine NuacareRocky.
The VM session was aborted.
Result Code: NS_ERROR_FAILURE (0x80004005)

I tried a few things as suggested on youtube, but nothing worked. finally, I just upgraded the extension and it worked.
WSL2 stopped working suddenly. If I do a new installation of linux distros. Then it throws the following error, when I click launch button for the linux distro from play store:
Installing, this may take a few minutes...
WslRegisterDistribution failed with error: 0x80070003
Error: 0x80070003 The system cannot find the path specified.
the wsl --help command works properly. All other wsl command hangs or throws error as shown below
like wsl -l command throws this error
The system cannot find the path specified.
I had the same thing happening to me after I moved the directory of my distro.
You have to unregister the distro from WSL;
wslconfig /u Ubuntu-20.04
and then just execute the installed exe and install the whole distro to WSL again.
I had to reinstall the windows to fix the issue. Something got corrupted in the OS. However, before reinstalling the OS as I had lot of work stored in the WSL2, I took the backup of the entire WSL2 image, the big .vhdx file. This file is the Virtual Hard Disk of WSL2 Linux. The files inside cannot be directly explored from Windows at the moment.
If one has not moved the file anywhere else, it is stored here: %LOCALAPPDATA%\Packages\<PackageFamilyName>\LocalState\ext4.vhdx
Before reinstalling the OS, after taking the backup, I wanted to test if this backup runs fine on new install of WSL2. For that, I tested it on another machine, by installing the same Ubuntu WSL2 distro and replacing the .vhdx file created with the backup file. It ran fine.
So, it felt safe to do entire OS reinstall and then reinstalling WSL2 Ubuntu and finally replacing the .vhdx file with the old backup .vhdx file. So, I did loose some time. But, my data and all the applications/programs on WSL2 were intact.
I know this is old but I had the same problem after deleting a driver associated with Hyper V and fixed it by uninstalling the virtual machine platform and Windows Hypervisor along with WSL, rebooted, reinstalled all 3 and then I could install Ubuntu again
This is my first answer on stack overflow and English is not my first language.
So, I will answer this question in images. My solution would not delete the date in any existing installed Linux distribution, at least for me.
Hope you can solve this problem successfully.

"Enable" Virtualization from your bios settings.
Settings may differ from bios to bios (search for your machine options)
If I want to run another version of tensorflow or keras, then I can install the same with specific version. But after that I want to rollback to latest version, and install tensorflow again with latest version say 1.6.0rc, it is installing, but when I check the version again, it is still pointing to earlier version of tensorflow. How can I overwrite earlier version with latest one?
If I restart runtime, it is not affecting the software installed, it is only resetting application variables.
The other way is to restart the virtual machine itself, but how do I do that?
Or I need to close colab portal and wait for some time(not sure how long?) and then open the portal again with hope that it would start new virtual machine....
Any clarifications on these are greately appreciated
To reset your backend, select the command 'Reset all runtimes...' from the Runtime menu.
You can try to restart the entire VM with !kill -9 -1. Check this: enter link description here
I have just installed fresh Arch Linux with XFCE4 and downloaded WebStorm. I did everything exactly as it is said in howto file (by executing .sh from bin folder). When i click on the WebStorm icon it looks like nothing is happening but suddenly after around 90s (and its min. value, i wonder how long it would be including project loading..) window pops up showing loading process.
I have pretty strong laptop with i7, 8gig of ram and SSD. There isn't any project loading also. It's fresh start. It used to work on Xubuntu, but it seems like i missed something during installation process or I dont know..
It's recommended to use OracleJDK not OpenJDK.
And try to trace what is happening while loading from terminal because if there is any error it will appear immediately.
Suddenly, i lost all Geny motion emulators (maybe after upgrading to Geny motion 2.2, not sure) and when ever i download a new virtual machine or emulator i get the "failed to import OVA" error and i can't use the virtual machines i downloaded at all in Geny motion, however they work in virtual box!
and i have cleared the cache and deleted old OVAs and re-downloaded other emulators again and again, but it's no use!
any clue what's going on?
is there a way to re-import emulators i already downloaded by Geny motion to Geny motion again instead of keeping downloading new emulators and getting the same error?
I solved the problem for myself. In my case, I had the same problem after defragmenting my computer. Deleting the ova and deploying files did not work (neither did reinstalling help). Solved it by clearing the cache in the app itself:
Settings>Misc>Cache Usage>Clear Cache
Try to see if that helps. If it doesn't then I can't help.
So I upgraded to the latest version of Genymotion 2.6.0. Tried to install the new Virtual Devices and I got the same error.
I tried to clear the cache as suggested above but it didn't help instead it removed the downloaded .ova file of the device and I had to download again.
I checked for update on VirtualBox and it shows that you're on the latest build. I checked the version and it showed 4.2.x.
Checked the latest version on the site and damn... It was version 5.0 available on the website.
Upgraded the VirtualBox to the latest 5.0 and here you go... Everything was back in place and my Genymotion Virtual Device was imported and is running fine.
So do check the versions of VirtualBox and see if it is the latest available on the website.
Deleting the Genymotion cached .ova file, deleting the corrupted deployed image, redownloading the image, and reinstalling it addressed the issue for me.
Note that the deployed images are under: ~/.Genymobile/Genymotion/deployed
the cached ova files are under: ~/.Genymobile/Genymotion/ova
this link : Unable to create Genymotion Virtual Device
Update :
Settings>Misc>Cache Usage>Clear Cache
Try to upgrade VirtualBox to the latest release, this solved the problem for me.
UPDATE
Some VirtualBox version are not compatibles with genymotion: review FAQ Genymotions in https://www.genymotion.com/help/desktop/faq/#compatible-virtualbox-versions
If you see the log file of Genimotions you'll find this:
VBoxManage.exe: error: 'Linux_64' is not a valid Guest OS type
The problem is the version of Virtual Box, I thought I had the last version (4.2) because virtual box said me that it was the lastest version, but it wasn't true: The last version actually is 5.0.20
I've installed the last version (5.0.20), and ova is ok
If you're using Windows:
The folder left after uninstallation is located at:
C:\Users\Your_User_Name\AppData\Local\Genymobile\Genymotion\
Before proceeding, in the OVA folder, save the ova files in there if you do not want to redownload the images all over again.
Clear the Genymotion cache, and then uninstall Genymotion (and Oracle VBOX if needed)
Remove the whole Genymotion folder in the above path
Reinstall genymotion and VirtualBox
Copy back the ova files into the ova folder.
Re-add the virtual device accordingly (the ova files name should be identifiable easily enough)
Genymotion will then verify the integrity of the stuffs and should now works fine.
I just Run Genymotion with Administrator right (run as Administrator)! It work perfect!
I had the same issue and also tried deleting the Genymotion cached .ova file and old images but to no avail.
To get my Genymotion working again in my environment I completely uninstalled VirtualBox and Genymotion using the TrashMe app to ensure no trace was left on my system. You can achieve the same result with the free app App Cleaner.
I then completely deleted the ~/.Genymobile directory as this seems to get left behind when deleting/uninstalling Genymotion. I think this is the only thing I did differently this time.
I then re-downloaded the latest versions of VirtualBox and Genymotion and installed them in that order. (Versions at time of writing: VB - 4.3.13 r93733 / GM - 2.2.2)
I then launched Genymotion, connected to my account, added a new device and I am now back up and running.
Hopefully that helps..
I encountered this error when my hard drive was almost full. It looked like it had enough space for the emulator, but Genymotion still failed with failed to import eva
Solved by freeing up a couple Gigs on disk.
Updating VirtualBox to the latest version, Worked for me
I deleted all the virtual devices and cleared Cache. After that I added the device again. Worked for me.
I had the same problem, I fixed it with uninstalling, reinstalling and running Gennymotion with Admin rights. Make sure you not upgrade Oracle VM and use the one you installed with Genymotion. Also at installing Genymotion make sure you reinstall VM too. It should work, I lost my devices too and this method only solve the OVA problem. If you run the virtual device and get an error, reboot computer, if you didn't do after installing Oracle VM. Hope it helped.
it turns for me I restored the system from the backup
Click geny settings->virtualbox tab, have to correct the folder to keep the VM
I had deleted /Users//.Genymobile/ directory and Genimotion started work fine
make sure you choose the correct android sdk
in Linux
just delete
home/user/.config/Genymobile/Genymotion.conf
and it's work
I downloaded ova that match with version i want (example android 5)

then add ova file to genymotion
