A few things:
1. git allows directories to be shared by multiple users. This is helpful when an enhancement is being worked on by a team where a number of users are contributing to the same clone at the same time.
2. Git detects that the .git directory (or files inside that directory) are not owned by the user performing the command, like git commit. That's where the message:
fatal: detected dubious ownership in repository at '/srv/git/projects.git'
To add an exception for this directory, call:
git config --global --add safe.directory /srv/git/projects.git
comes from. This part of the message is considered a fatal error because you have not declared that this is a shared repository. Once you execute the git config, you should not receive this message.
3. The actual error, in this case, is probably coming from a lack of access to more than one file in the .git directory (a.k.a. metadata). Rather than reporting all files, the implication is to check the security and owner in the .git directory and fix those first. This likely results from a user sharing the repository who has an incompatible umask (if Linux) or unshared security settings in Windows or something else if NFS or other file system.
4. IIRC, in a situation where a file without proper security is in the working index (outside .git), I believe git does report an error specifying the exact name of the file that caused the problem. In your case, there is a high probability that the .git directory (some or all) contents are not readable by your user.
Please check the assumptions. I think fixing #2 and #3 should help.
