</span>My guess at this point is that somehow your local cache is messed up. That<br>
still really doesn't explain why we hang there, though.<br>
<br>
How good are you with a debugger? The best way to deal with this would be<br>
to set a break point on the call to git_remote_push() in git-access.c<br>
and then step through the next few instructions to see where we get stuck.<br>
<br>
If this isn't something you are comfortable with I can add more debug<br>
printouts that will tell us if it really is git_remote_push() or possibly<br>
something else that's causing the problem.<br>

</span>Yes, as I said above. I no longer think it's the connection.<br>
I wonder why it failed the second time around but that could just have<br>
been a fluke.<br>

</span>OK. That makes more sense.<br>

Two possible things to try<br>
<br>
a) blow away the local cache (it's in ~/.local/shared/Subsurface/Subsurface/<sha of the remote>)<br>
and try again. While that should cause things to just freeze, that is a<br>
