"Permission denied" when deleting files inside of .git folders - github-actions

I'm getting an error in my self-hosted github runners:
rm: cannot remove '/home/user/github-actions/1/_work/project/project/.git/index': Permission denied
It's not just this one file, but all the files that it tries to delete.
If I run something like: sudo chmod -R 777 . in the home directory, it will temporarily fix it. But the issue will come back. What can I do to fix this permenantly?

When your runner fails with this error, double-check the output of:
ls -alrth /home/user/github-actions/1/_work/project/project/.git/index
ps -eaf|grep -i runner
That way, you can see:
who has created that file
what user is executing the current runner process
That allows you to confirm a user process issue (one executing the runner, the other the files).
I wonder if Git is running as a separate user or something
No, it should not.

Script that uses google-drive-ocamlfuse fails when run through Rundeck

I have a script that runs fine when run directly from the shell of the server hosting Rundeck. It uses google-drive-ocamlfuse to mount my google drive to a local directory, creates a folder in the directory, and then unmounts.
name=New-Folder-Name
google-drive-ocamlfuse /home/user/mygoogledrive/
mkdir /home/user/mygoogledrive/$name
fusermount -u /home/user/mygoogledrive/
If I try to run this as an ad hoc command in Rundeck:
sudo ./var/lib/rundeck/scripts/create-folder.sh
... it errors out with:
Error: no DISPLAY environment variable specified
/bin/sh: 1: google-chrome: not found
/bin/sh: 1: chromium-browser: not found
/bin/sh: 1: open: not found
Cannot retrieve auth tokens.
Failure("Error opening URL:https://accounts.google.com/o/oauth2/auth?client_id=REDACTING-PERSONAL-INFO")
mkdir: cannot create directory ‘/home/user/mygoogledrive/New-Folder-Name’: No such file or directory
fusermount: failed to unmount /home/home-db/mygoogledrive: Invalid argument
I am new to Rundeck and am not yet comfortable with permissions and I don't have a good sense of how a command is being run on the server by Rundeck. It must be accessing and executing the file, given the error output, but maybe there are some limitations in the environment due to permissioning that doesn't allow for the use of certain libraries need by google-drive-ocamlfuse? Any ideas?
To use sudo on a target remote node, you need to set the sudo parameters. Otherwise, if you need to use sudo locally, the easier way is to use this plugin in your Rundeck instance.

Access denied when using go get

I was using go get go get the go-sql-driver from github. When I ran the command go get -u github.com/go-sql-driver/mysql as prompted by the repo, I encountered an error saying "access is denied":
go: writing stat cache: mkdir C:\Program Files\GoPath\pkg: Access is denied.
go: downloading github.com/go-sql-driver/mysql v1.5.0
go get github.com/go-sql-driver/mysql: mkdir C:\Program Files\GoPath\pkg: Access is denied.
I am using Windows 10. This happened when I changed the %GOPATH% environment variable. Any suggestions on solving this?
It seems like Go doesn't have the right to access the "Program Files" folder. I created a GoPath folder at another place and go get seemed to work. However, it created a folder named "pkg" in "GoPath", but from the compilation file I am having, it looks like the package should be installed under an "src" folder. Could somebody please explain how this happened?
mkdir C:\Program Files\GoPath\pkg: Access is denied.
It looks like access denied while trying to create directory. Either change the installation directory or grant access to the path mentioned.
If it is your development machine or laptop, open Command Prompt as administrator and try installation.

Zabbix external checks cannot be executed due to SELinux

I try to implement external checks in Zabbix 2.2. I've created simple bash script for SSL verification which should be executed by zabbix service. The script is located in /var/lib/zabbixsrv/externalchecks directory. Even if there are 777 permission for the .sh script I still receive message telling
unable to execute /var/lib/zabbixsrv/externalscripts/test.sh: Permission denied
I've got same message when I try to run the command even as root. The ls -Z /var/lib/zabbixsrv/externalscripts/test.sh command output says:
-rwxrwxrwx. zabbixsrv zabbixsrv unconfined_u:object_r:default_t:s0 /var/lib/zabbixsrv/externalscripts/test.sh
There is no message relating this in /var/log/massages. Does anybody know how to force selinux to allow execute zabbixsrv user the script without disabling selinux?
Which zabbix service (zabbix-server, zabbix-agent, ...) should execute the external checks script?
Did you tried to set AllowRoot=1 in /etc/zabbix/zabbix_agentd.conf?
The main issue was in /etc/fstab configuration file. The Zabbix has defined as default values for script /var/lib/zabbixsrv/excernalscripts directory. My server has /var mounted with rw and noexec permissions.
I've already moved the script to different location and change the configuration file accordingly. Checks are working fine now.
Thanks everybody for any contribution relating this topic.

Jenkins Mercurial not trusting file

I using mercurial and I am trying to point Jenkins toward custom directory. I ran into this error,
Started by user Netro
Building in workspace <path-to-workspace>
[workspace] $ hg showconfig paths.default
ERROR: Workspace reports paths.default as Not trusting file <path-to-workspace>/.hg/hgrc from untrusted user root, group root
Not trusting file <path-to-workspace>/.hg/hgrc from untrusted user root, group root
which looks different than http://ip-address/project so falling back to fresh clone rather than incremental update
ERROR: Failed to clean the repository checkout
I had searched internet and it suggested add trusted field. I had tried with following code in ~/.hgrc, /etc/mercurial/hgrc, <path-to-workspace>/.hg/hgrc
[trusted]
users = jenkins, root
But it doesn't remove error.
When I was not using custom directory option. It ran successfully.
Installation of Jenkins and repository was done with user root on Ubuntu 1204.
Any suggestions will be helpful.
It seems, hg was not able to accept jenkins as owner of the projects. Jenkins in default directory creates workspace with user Jenkins. So it is able to run it. I added Jenkins in group root and changed the owner of project from root to jenkins. Now projects are updated from Jekins.

As far as I can see this means that it can't find the hg executable. However, I get no such errors when I try executing hg as a build step (shell execute) with Mercurial integration disabled.
I've tried with and without changing installation directory and executable and I've even tried compiling (well, whatever of that there is) Mercurial manually from source, all to no avail.
EDIT: Silly me. I completely misread the log. The issue is not related to it not finding the hg executable at all, but it's actually because I forgot to set up my key properly.
Inspecting http://localhost:8080/systemInfo Environment Variables > PATH displays "/usr/bin:/bin:/usr/sbin:/sbin". I can't determine why this is all that Jenkins sees. When logging in as the daemon configured user, I get a much larger set of paths.
I was able to help the Mercurial Plug-in find "hg" by creating a symlink to hg.
sudo ln -s /usr/local/bin/hg /usr/bin/hg
I tried adding the following to /etc/profile (I restarted just in case)
PATH=$PATH:/usr/local/bin
export PATH
I verified that this modified my path by typing
echo $PATH
in Terminal. However, this path did not show up in Jenkins
I am able to work with the sym link solution but I'd really like to understand where Jenkins gets its Path.
Nullable is right, the issue isn't that the hg executable can't be found, but rather that the jenkins user doesn't have a public key.
The solution is as follows:
Log in as the jenkins user
Make sure the jenkins user has a public ssh key, which should be in .ssh/id_rsa.pub
If not, generate one using ssh-keygen and don't specify a passphrase
Issue cat .ssh/id_rsa.pub, copy the output.
Log into bitbucket or github, add the public key you just copied into your account
Try again!
Hope that helps, best of luck to anyone with this issue.
My first thought would be that you should check the path to the hg executable in jenkins set up, if there is such an option, it may not point to the correct path.
If that doesn't help, make sure hg is on the PATH.
Looks like there might be some set up required according to this page http://www.pixelastic.com/blog/162:failed-to-import-extension-hgext-imerge-warning-on-dreamhost
Maybe that can fix your issue?
