Unable to start seahub after minor upgrade (6.2.2 -> 6.2.5)

I ran a minor upgrade as root from Seafile 6.2.2 to 6.2.5
Now Seahub won’t start anymore.

seafile@Ubuntu-1604-xenial-64-minimal:~/seafile-server-latest$ ./seafile.sh start

[02/12/18 16:03:23] ../common/session.c(132): using config file /opt/seafile/conf/ccnet.conf
Starting seafile server, please wait ...
Seafile server started

seafile@Ubuntu-1604-xenial-64-minimal:~/seafile-server-latest$ ./seahub.sh start

LC_ALL is not set in ENV, set to en_US.UTF-8
Starting seahub at port 8000 ...
Error:Seahub failed to start.
Please try to run "./seahub.sh start" again

I read afterwards, that I should have been logged in as the seafile user. Which I was not. Therefore do I have to chown some folders? I don’t know which ones.

Everything under the home directory for the seafile user needs to be owned by the seafile user.

Fix that and try again.

Thank you, running the following as root

sudo chown -cR seafile /opt/seafile

fixed the problem!
