Description

In recent gitea versions importing from local files fails with the error "modules/task/task.go:51:handle() [E] Run task failed: migrate from '' is not allowed: unknown hostname".
This appears to be an artifact of #13610 which attempts to verify IP address range even for local files.
Consequently setting [migrations]ALLOW_LOCALNETWORKS = true works as a fairly non-obvious workaround

See:

https://docs.gitea.io/en-us/config-cheat-sheet/#migrations-migrations

in particular:

ALLOW_LOCALNETWORKS: false: Allow private addresses defined by RFC 1918, RFC 1122, RFC 4632 and RFC 4291

In the [migrations] section in app.ini set:

ALLOW_LOCALNETWORKS=true

I don't think this is resolved. The problem is the form file:///home/git/repository/a.git is not supported.

Ok well that's slightly different from what the report initially stated. I'll reopen.

I understand now! Sorry it took me so long to get what the problem was.
