Gitea: Migration does not work

Hi,
I just installed Gitea via Snap. However, when I try to migrate a repository from e.g. GitHub I get the following error in the logs:

Migrate repository from https://github.com/wmutschl/Test.git failed: Clone: exit status 128 - warning: templates not found /usr/share/git-core/templates
fatal: Unable to find remote helper for 'https'

There is this issue on their GitHubs page, but I was wondering if anyone has a workaround here?
