That is:
hashanp#DESKTOP-9E00J4S: ~/cats-cakes$ git add .
error: open("img/cake.jpg"): Permission denied
error: unable to index file img/cake.jpg
fatal: adding files failed
Trying to add image in Git add but keep getting the following message? I tried restarting/reloading git and closing VS Code but nothing worked.
That looks like a git bash session on Windows, or a WSL session.
If you can not easily identify the process which keeps an handle to that file, preventing another program (like git) to access it, I would:
reboot
restart my git bash or WSL2 session
try to add img/cake.jpg before opening any IDE.
Since it is an Ubuntu session, I would also try, for tesdting:
sudo chmod -R 755 img
That way, the folder img will be accessible.
I am trying to run a filewatcher.sh script in background. It further invokes a java code through a jar file.
Whenever I run the command("nohup sh filewatcher.sh") through terminal, everything is ok. I have to hit enter two times so the output file is appended to nohup.out. But whenever I try to run the equivalent command("nohup filewatcher.sh >> nohup.out < /dev/null &") from a shell script automate.sh, I get following permission error.
error-log. Click to see snippet.
Could this an issue of permission for the automate.sh?
I have crossed check to see this script is having same permissions and ownership as the user when I log in and enter the nohup command from command line.
I also checked the ownership of the folders where the files are getting moved but everything is having same permissions and ownership.
I have a Google Compute Engine VM instance with a Asterisk Server running on it. I get this message when I try to run sudo:
sudo: parse error in /etc/sudoers near line 21
sudo: no valid sudoers sources found, quitting
sudo: unable to initialize policy plugin
Is there a password for root so I can try to change it there? Any suggestions on this?
It looks like you have manually edited the /etc/sudoers file so while you would normally have sudo access, due to the parse error, you won't be able to do this directly.
Here's how to fix this situation.
1. Save the current boot disk
go to to the instance view in Developers Console
find your VM instance and click on its name; you should now be looking at a URL such as
https://console.cloud.google.com/project/[PROJECT]/compute/instancesDetail/zones/[ZONE]/instances/[VM-NAME]
stop the instance
detach the boot disk from the instance
2. Fix the /etc/sudoers on the boot disk
create a new VM instance with its own boot disk; you should have sudo access here
attach the disk saved above as a separate persistent disk
mount the disk you just attached
fix the /etc/sudoers file on the disk
unmount the second disk
detach the second disk from the VM
delete the new VM instance (let it delete its boot disk, you won't need it)
3. Restore the original VM instance
re-attach the boot disk to the original VM
restart the original VM with its original boot disk, with fixed config
How to avoid this in the future
Always use the command visudo rather just any text editor directly to edit the /etc/sudoers file which will validate the contents of the file prior to saving it.
I ran into this issue as well and had the same issue Nakilon was reporting when trying the gcloud workaround.
What we ended up doing was configure a startup script that removed the broken sudoers file.
So in your metadata put something like:
#/bin/sh
rm "/etc/sudoers.d/broken-config-file"
echo "ok" > /tmp/ok.log
https://cloud.google.com/compute/docs/startupscript
As you probably figured out this requires the /etc/sudoers file to be fixed. As nobody has root access to the instance, you will not be able to do this from inside the instance.
The best way to solve this is to edit the disk from another instance. The basic steps to do this are:
Take a snapshot of your disk as a backup (!)
Shutdown your instance, taking care not to delete the boot disk.
Start a new "debugger" instance from one of the stock GCE images.
Attach the old boot disk to the new instance.
In the debugger instance, mount the disk.
In the debugger instance, fix the sudoers file on the mounted disk.
In the debugger instance, unmount the disk
Shutdown the debugger instance.
Create a new instance with the same specs as your original instance using the fixed disk as the boot disk.
The new disk will then have the fixed sudoers file.
Since i bumped into this issue too, if you have another instance or any place where you can run with gcloud privileges, you can run:
gcloud compute --project "<project id>" ssh --zone "europe-west1-b" "<servername>"
I ran this on a server which had gcloud as root, so you login to the other box as root too! Then fix your issue. (if you don't have a box, just spin a micro up with the correct gcloud privileges) saves the hassle of disk stuff etc.
As mentioned in above comments, I am getting the same error like below in gcp VM.
sudo: parse error in /etc/sudoers near line 21
sudo: no valid sudoers sources found, quitting
sudo: unable to initialize policy plugin
To solve this
I have ssh to another vm and become root then I ran gcloud ssh command to our main vm (where you are getting the sudo error.)
gcloud compute --project "<project id>" ssh --zone "europe-west1-b "<servername>"
And BOOM!, now are login as root in the VM.
Now you can access/change the /etc/sudoers file accordingly.
I found this hack better than recreating vm/disks.
Hope this helps to someone!
It is possible to connect to a VM as root from your developers console Google Cloud Shell. Make sure the VM is running, start the shell and use this command:
gcloud compute ssh root#<instance-name> --zone <zone> [--project <project-id>]
where instance-name is found in the Compute Engine VM Instances screen. project-id is optional but required if you are connecting to an instance in a different project from the project where you started the shell.
You can then fix this and other issues that may prevent you from using sudo.
I got a Permission denied error when trying to ssh to the problem instance via gcloud. Using a startup script as mentioned above by #Jorick works. Instructions for it are here. You will have to stop and restart the VM instance for the startup script to get executed. I modified the script slightly:
rm -f /etc/sudoers.d/google_sudoers >& /tmp/startup.log
After the restart, launch an SSH session from the cloud console and check that you are able to view the file contents (with sudo more /etc/sudoers.d/google_sudoers for example). If that works your problem has been solved.
I just worked with Windows 7 before and now I'm working with MAC OS. I cloned my project (it works with Twig and wordpress and I'm using a virtual machine via vagrant) and everything should work but when I enter the website it gives me the following message:
Uncaught exception 'RuntimeException' with message
'Unable to create the cache directory (/vagrant/myProject/cache/c2/94).'
in /vagrant/myProject/wp-content/.../libraries/Twig/Environment.php:1199
I guess it is some kind of problem about permissions but I don't know how to fix it exactly. Any help? Thank you.
As soon as you created a /vagrant directory, I think default permissions are root.
You can try:
sudo mkdir /vagrant/myProject/cache
sudo chown -R $USER:staff /vagrant
And then try again (assuming your current user runs the apache server).
If this does not work, please do:
ls -l /vagrant
and:
ls -l /vagrant/myProject/cache/
And try to set permissions so the cache permissions are the same.
Im running as root on a smartos64 machine.
My database is at /data/db
Mongod is at /mongo/bin/mongod
I get a 'permission denied' error with no further details when running either
- run ./mongo/bin/mongod or
- sudo ./mongo/bin/mongod
I tried changing permissions with chown on /data/db, but I still get this behaviour. How would I start mongo?
What build of Mongo did you download? I believe SmartOS64 is a derivative of Solaris, so I would try a Solaris build from the Mongo download site. If that doesn't work, you may want to build it from source.
