</span>I am sure you guys have a problem but one
doesn't need Jupyter to do<br>
actual programming in Python. I am saying this
because there are<br>
handful of you who are affected by this behavior
(God knows what could<br>
have caused possibly even regressions by newer
version of packages) and<br>
I am the only firefighter currently without
bandwidth to deal with such<br>
wild fires.<br>

</span>The git issue is environmental variable
issue which is caused by the<br>
fact that there is only one user on Gogs server
(git) and all accounts<br>
are just aliases with their own ssh-keys to this
account. I don't use<br>
and know enough about git but those nasty files in
your<br>
<br>
reponame/.git <br>
<br>
folder <br>
<br>
which look like <br>
<br>
predragp@lov3$ ls<br>
branches description HEAD index logs
ORIG_HEAD refs<br>
config FETCH_HEAD hooks info objects
packed-refs<br>
<br>
apparently get populated in different ways
depending on the login. So<br>
for example if I ssh to one of the computing nodes
from home I get this<br>
<br>
