Description

Commits afd89b1 (and 58f57b3) have an issue where all public SSH keys are rejected. This does not happen with commit f8601f3. I have been able to test this on try.gitea.io, and this is the error I get:

git clone git@try.gitea.io:bkraul/TestProject.git
Cloning into 'TestProject'...
fatal: 'bkraul/TestProject.git' does not appear to be a git repository
Gitea: Internal error
Failed to execute git command: exit status 128
fatal: Could not read from remote repository.

Please make sure you have the correct access rights
and the repository exists.

The repository does exist and the public SSH key is valid.

Without logs we cannot assess further. We need the logs from the running gitea server.

This was done on try.gitea.io. I can send you mine, but I don't see much on there, tbh.

This is all I get. These are 2 tries to do a git pull action (some info modified for privacy):
