After following the Google Devboard Getting started guide, I finally flashed the devboard with the latest enterprise-eagle-20200724205123 Mendel 5.0 OS. However, when accessing it from the console, I get this:
Cannot open access to console, the root account is locked.
See sulogin(8) man page for more details.
mdt devices does not recognize the board too.
Any help?
This error likely means that your file system partition or mounted devices don't match what's in /etc/fstab on the device. This could happen for example if you had an SD card auto-mounted in /etc/fstab without the nofail param and tried to boot without that card. This would result in the error you're seeing. If that is the case then try inserting an SD card and see if you can login. I belive that the partition table on the Eagle release and the previous release are different, so there might also be a scenario where you updated to Eagle without doing a complete re-install might also cause this error. In that case, I'd try a complete re-install.

I have developed an application for MacOS. I am including notarization process as part of its distribution. I have followed all the steps and I have run:
xcrun altool --notarize-app --primary-bundle-id "${APP_BUNDLE_ID}" --username "${APPLE_DEV_ID}" --password "${DEV_APP_SPECIFIC_PASSWORD}" --file "${DMG_PATH}"
Then I check notarization progress using:
xcrun altool --notarization-info "${notarize_uuid}" -u "${APPLE_DEV_ID}" -p "${DEV_APP_SPECIFIC_PASSWORD}
Output of it is:
RequestUUID: =<Request>
Date: 2019-05-26 09:40:34 +0000
Status: success
LogFileURL: <Log file>
Status Code: 0
Status Message: Package Approved =~ success ]]
Then I launch staple command:
xcrun stapler staple -v <dmg file>
It also ends with success:
The staple and validate action worked!
However when I extract the .app file and run:
spctl --assess --verbose ./macos/MyApp.app
./macos/MyApp.app/: accepted
According to the docs I have read it should say something like: “source=Notarized Developer ID”, right?
I am running this on MacOS Mojave 10.14.5
What am I missing??
Could someone help me?
Thanks in advance
In case someone faces the same problem I will post the solution to this:
First of all you must staple .app file not the dmg. This means you must extract the binary and staple it
Also in order to check if application has been notarized, in
`System Preferences - Security and Privacy`
Option Allow apps downloaded from: must have Apple Store and identifier developers option checked
Hope this helps
Both the app and the dmg may be notarized and stapled, seperately, one after the other. Try doing that and the error should go away.
Short answer
It could be due to an RPATH referencing a path outside the App bundle. Removing this RPATH would resolve the issue.
Inspecting log files
You can find extra information about the rejection (after trying to launch the blocked app) in the Console.app. Note that you should open the Console.app, before trying to open your blocked app, otherwise not all messages may be logged. You should look for process XprotectService in the logs of your device (i.e. choose your device in the left side bar of the Console.app). If the RPATH is indeed the problem, you should find a record like this:
XprotectService: [com.apple.xprotect:xprotect] File /path/to/your/executable/or/library failed on rPathCmd /rpath/causing/the/problem (rpath resolved to: (path not found), bundleURL: /path/to/your/bundle.app)
Inspecting these log files may give you a key to solve other issues too.
Note that I received the following information from an Apple engineer:
Gatekeeper does not inform users via UI about the specifics of the
error, though it is in the logs for developers to look at. The
notarization process is purely about a detecting malicious software
and does not replicate Gatekeeper enforcement. You still need to get
software notarized and test with Gatekeeper.
We are looking to provide better tooling for developers in the future
to pre-flight some of these common errors.
Contact Apple
If you are not able to solve your issue with the above information, you may want to contact Apple itself using the Feedback Assistant. They do not respond very quickly (~1-2 weeks), but the answers are rather to the point.
I've recently purchased a BeagleBone Black. I installed the drivers, got myself a SD card and an external card reader,7yip and win32 disk imager just like the Beaglebone startup guide told me to. However, when I put my disk on the micro-sd card and insert that into the Beaglebone, I need to tell it to boot from micro-sd.
For that I need to go to the SSH terminal (putty) and type the following:
sudo nano boot/uEnv.txt
In that I need to remove the # at the start of
#cmdline=init=/opt/scripts/tools/eMMC/init-eMMC-flasher-v3.sh
for it to boot off the SD. The first time I did this, it worked. I was just navigating down to the line of code when putty told me that it has disconnected. The next dozens of times I tried to access uEnv.txt, it was completely empty. I don't know why it crashed, nor have I found out how the hell I get it to work. I have unzipped the original file again and installed a new disk several times now, but it's still empty.
EDIT:
Hmm, I've heard win32 disk seems to be unreliable. I'll attempt to use another program, but I don't think that's the problem. But take this into consideration
I found the answer!
I asked a guy I know who has more knowledge in this area. It turns out all this time I was just creating a NEW uEnv.txt file. For all other people who might be struggling with this; The command to open the uEnv.txt file is
sudo nano ./boot/uEnv.txt
The ./ plays a very important role here. From there you can edit the file as you wish.
I hope this helps!
Since it took me quite some time to figure out how to get Xtion (Primesense) to work on VMware I thought to share it here with you. (with Kinect I have a problem to let ROS see the device even though VMware has successfully connected it).
roslaunch openni2_launch openni2.launch
Running the above command gave me the error:
Warning: USB events thread - failed to set priority. This might cause loss of data...
I either got a single frame or no frame when running "rviz" and Add --> Image --> Image topic --> /camera/rgb/image_raw
So how do I get video frames in Ubuntu from a Primesense device while using a Virtual Machine (VMware)?
My specs
Windows 7 running VMware 10.0.4 build-2249910
Ubuntu 12.04.5 Precise in VMware
ROS Hydro
The following question pointed me in the right direction: http://answers.ros.org/question/77651/asus-xtion-on-usb-30-ros-hydro-ubuntu-1210/?answer=143206#post-id-143206
In the answer of blizzardroi (not selected answer) he/she mentions that USBInterface should be 0. I reasoned that since my main Machine is Windows, I should set UsbInterface to 1, which indeed solved it.
Solution
Go to /etc/openni2/ (from system folder, not Home) and open PS1080.ini with administrator rights (e.g. sudo gedit PS1080.ini). Search for UsbInterface, remove the ; and change the value to 1. It should look like below:
; USB interface to be used. 0 - FW Default, 1 - ISO endpoints (default on Windows), 2 - BULK endpoints (default on Linux/Mac/Android machines)
UsbInterface=1
Additional
From previous experience it may also be related that your Windows system may need the kinect drivers as well. If the above not works, try to install the following:
(Kinect SDK) https://www.microsoft.com/en-us/download/details.aspx?id=34808
(OpenNI2 Windows) http://structure.io/openni
p.s. Don't forget your drivers for Ubuntu (replace hydro with your ROS version)
sudo apt-get install ros-hydro-openni*
Important
It doesn't solve the error below, but rviz returns video, which means that we can read the data the Primesense device publishes!
Warning: USB events thread - failed to set priority. This might cause loss of data...
Got the same warning from opennni (issued at start by a binary located at Tools/PSLinkConsole) with another sensor.
Solved by starting process as sudo - my guess: to set priority to USB event threads you need root access. :)
I'm trying to have my app auto launch on login following Tim's tutorial: http://blog.timschroeder.net/2012/07/03/the-launch-at-login-sandbox-project/
I followed the instructions to the letter but I'm getting an error when I re-login to my computer as follows:
Jan 10 12:55:01 pc61 com.apple.xpc.launchd[1] (com.myApp.macgap.helper[25725]): Could not resolve CFBundleIdentifier specified by service: -10814: com.myApp.macgap.helper
Jan 10 12:55:01 pc61 com.apple.xpc.launchd[1] (com.myApp.macgap.helper): Service only ran for 0 seconds. Pushing respawn out by 10 seconds.
To outline:
I have my main app called "myApp" (ID: com.myApp.macgap )
In that app I have a helper app with ID: com.myApp.macgap.helper
When you launch the main app and go to preferences, you have an option to enable auto login (to fit to the Apple compliance rules)
I log out of my computer, log back in and look at the console to see what's going on (that's how I get the code above)
Another point worth mentioning, is when I do "Show package content" on the app and double click the helper app, it does launch the main app...
It all comes down to how launchd and launchctl work, as already answered, the regular use case often can be solved by reinstalling the app and ensuring the app is inside the applications folder. But there's another case that #byb is talking about, when this happens on your development machine – this can be caused by invalid launchd configuration.
When you run SMLoginItemSetEnabled it registers your bundle identifier along with other information in launchd service. At some point later, when your app changes, gets cleaned, or something else happens to it, which gets picked up by launchd, launchd may disable that particular login item. Apparently, sometimes this doesn't go smoothly, and consecutive calls with SMLoginItemSetEnabled will not work as expected or the agent / helper app simply won't launch.
The first thing to try is simply changing the bundle identifier for your launcher. If this solves the issue, try figuring out what's wrong with the original. Run launchctl print-disabled "user/$(id -u)" to display disabled services and login item associations. If the output contains your troubling bundle identifier – you are in luck.
I didn't find a way of removing disabled services by name using launchctl and had to do it by manually editing configuration files. Because they system-owned, you won't be able to simply click and edit, instead launch Xcode as root and remove the necessary references.
sudo /Applications/Xcode.app/Contents/MacOS/Xcode "/private/var/db/com.apple.xpc.launchd/loginitems.$(id -u).plist"
sudo /Applications/Xcode.app/Contents/MacOS/Xcode "/private/var/db/com.apple.xpc.launchd/disabled.$(id -u).plist"
Restart, run launchctl print-disabled "user/$(id -u)" to confirm removed items are no longer in the list. Try SMLoginItemSetEnabled again, hopefully now it will work as expected.
I had the exact same problem just now, and while looking for a solution found this (unanswered) question.
At least in my case, this desired functionality of the worked fine when I copied the app (exported from Xcode as a dev-id signed .app) to a fresh OS X install/account without all my development stuff on it. Of course it must also be in /Applications, as stated in the tutorial referred to in the question.
I am not sure why this feature of the app did not work on my development machine. Perhaps the problem could be due to some form of conflict with all the other near-identical copies of my app I have on disk (I have an archive of different versions of the app, plus the copies Xcode stores itself), all with the same bundle id of course.
Hope this helps in one way or another!
I had the same problem, removing other copies of app except one in /Applications solved the problem for me. To remove .app files generated by Xcode you can run Product->Clean.
I was struggling with this for hours. I had many apps with auto login but a new one just did not want to work.
Strangely this worked on the development machine:
Build App as normal
Move it to Application directory
Clean Xcode (CMD+k)!!
Enable auto login in the app.
Logout Login
I accidentally noticed that the system started the app (it tries in every 10 sec) when I clean Xcode :)
I can't find the duplicate copy but did find you can remove the service:
In a terminal window:
launchctl remove com.annoying.service
As it was already stated if there are more then one copies of service bundle on the machine launchd cannot resolve which one must be started by bundle identifier.
What I would recommend to you is find all copies of your service and then remove not desired ones.
For this you need to run following Swift code (It works even in Swift Playground):
import Cocoa
let bundleId = "com.your.bundleId"
let paths = LSCopyApplicationURLsForBundleIdentifier(bundleId as CFString, nil)
print("Available service instances by bundle id: \(paths)")
In my case it produces:
Available service instances by bundle id:
Optional(Swift.Unmanaged<__ObjC.CFArray>(_value: <__NSArrayI 0x6000002234a0>(
file:///Applications/MyApp.app/Contents/Library/LoginItems/MyService.app/,
file:///Users/igor/Library/Developer/Xcode/Archives/2017-12-27/MyApp%2027-12-2017,%2016.06.xcarchive/Products/Applications/MyService.app/
)
))
So I easely identified copy to be removed:
file:///Users/igor/Library/Developer/Xcode/Archives/2017-12-27/MyApp%2027-12-2017,%2016.06.xcarchive/Products/Applications/MyService.app/
Hope it help.
Assuming that you followed Tim Schroeder's recipe at: http://blog.timschroeder.net/2012/07/03/the-launch-at-login-sandbox-project/ :
What actually ended up working for me, was, in Xcode, to change my main project's build number from 1 to 2. I also tried a build number of 1000 and that worked fine as well.
In Xcode, select your main project target. Then, select the 'General' tab. If you see your Build is set to 1, change it to 2 and then rebuild, redeploy and see if that resolves the issue for you.
This was probably one of the screwiest bugs I have run into, in a while.
I'm writing app like System Activity in Mac. I used modified darwin.h and darwin.c from this topic.
But it seems that it shows correct info only for certain fields (and some time ago it showed all correct info but only for current process - this app), for everything else it shows correct only pid, process name, group/owner. Everything else like cpu/mem/disk usage is nulled. I think it may be something with sandbox or security. Tried to move application to /Applications and setting root/wheel 755 but it's not work, still zeroed values.
Here's my output : click
Code changed in darwin.c : click, written after a lot of commented printf lines
Also there is a free apps approved in AppStore like SystemInfo (com.lymbilesoft.systeminfoliteforiphone) that shows detailed info about disk and processes, so how do it work? Tried nm-ing it's binary but did not find something useful.
Can someone please help me with it?
I'm not sure if this is the only problem, but it certainly is possible that your app needs to run as root for this to work correctly.
However, simply installing the app in /Applications, doing chown root.wheel, and chmod 755 will not cause it to run as root. It will still run as user mobile.
In order to get the app to run as root, see this answer
I've used this technique successfully, and if you have a jailbroken phone, you can navigate to /Applications/Cydia.app and see that this launch script is how Cydia does this, too.
I use ps aux from the Terminal/Command Line. That gives me all the stuff I need, regarding your concerns.
