Description:    Ubuntu 22.04.1 LTS

Release:        22.04

I'm trying to cron some git commands under the user www-data and it doesn't work.

To troubleshoot, I tried to run sudo -u www-data git show but it returns fatal: detected dubious ownership in repository

If I run sudo -u www-data git diff --shortstat it returns warning: Not a git repository. Use --no-index to compare two paths outside a working tree

I also tried adding into sudoers

www-data ALL=(ALL) NOPASSWD: /usr/bin/git show



# and also



www-data ALL=(ALL) NOPASSWD: /usr/bin/git

Still getting the same errors. Any ideas why? Thank you.

Git requires the current user to be the owner of the files, it does not work if current user is a "member" of the group

For .git files belonging to user1:group1

Git will not throw error if you are user1

Git will throw error if you are user2:group1

Solution 1 (Best)

Since this is automated/cron, it is easier to just prefix the user to run as. Specify the user before the git command

sudo -u <user> git ...

Solution 2

Slighting more cumbersome as you need to add every repository to the user's .gitconfig and there is a very detailed answer here https://stackoverflow.com/a/73100228/3872647

[safe]

    directory = <real path of git repository, symlink won't work here>

I hope this is clear enough, otherwise please ask or comment and I will modify this answer.
