Server Error (500) after log in as a super user

[HaKLMTT]

Before I log in , every thing goes well. I don't enable tf_annotation, because I have no Nvidia GPU.
Soon after I create super user using the following cmd:
docker exec -it cvat sh -c '/usr/bin/python3 ~/manage.py createsuperuser'
And go to http://localhost:8080/, after input user and password, in the next page showing

Server Error (500).

OS: Ubuntu
(Linux version 4.15.0-29-generic (buildd@lgw01-amd64-057) (gcc version 7.3.0 (Ubuntu 7.3.0-16ubuntu3)) #31-Ubuntu SMP Tue Jul 17 15:39:52 UTC 2018)

Need your help here. Thanks.

Hi @HaKLMTT ,

I guess you are using the development version. First of all please update till the latest version. Today we introduced a regression #129 in develop but it was already fixed.

Please let me know if you still have problems. In this case need to run docker logs cvat and send output to us.

I did as your suggestion:
root@ubuntu:/git/cvat# git pull
Already up to date.
root@ubuntu:/git/cvat# docker-compose build

However encounter the following exception:

After reboot the OS, the issue above disappear.
