UnboundLocalError: cannot access local variable 'updates' where it is not associated with a value

[litebito]

I noticed in the dashboard that my patchman server did not update everything correctly, so I ran patchman manually

/opt/patchman/.venv/bin/patchman --all

When doing that, I saw it failing with the following error:

I thought it was a bad mirror, so I disabled the mirror in the Patchman UI, and ran it again. After a while, again the same error for a different mirror.
I tried that a few times (disabling mirrors, hoping it would get past the error) but it keeps erroring out with a next mirror.

Any idea how we can fix this?
