Oct 26 14:09:31 uffizi python3[16259]: UnboundLocalError: local variable 'err' referenced before assignment
The message is not so clear but the code references (dulwich/client.py around line 643):
```
err = socket.error("no address found for %s" % self._host)
for (family, socktype, proto, canonname, sockaddr) in sockaddrs:
s = socket.socket(family, socktype, proto)
s.setsockopt(socket.IPPROTO_TCP, socket.TCP_NODELAY, 1)
try:
s.connect(sockaddr)
break
except socket.error as err:
if s is not None:
s.close()
s = None
if s is None:
raise err
```
So when trying to raise the 'err' variable, it's when s is None
and s is None when the socket opening somehow fails.
I don't grok why err is not defined since it is (maybe the try except which overrides it).
So it must be environment related (firewall or something).
Will try in another worker.

Well, an issue in dulwich was making unclear the reason.
Fixing the code in dulwich, made the error clear.
github.com was not resolved in uffizi (it is now).
