I have recently upgraded jupyterhub from 0.7 to 0.8.1. After upgrade, i have upgraded the sqllite database as well as mentioned in the upgrade documents. I'm able to start the jupyterhub service but after login, i'm unable to start the server with below error. My server is AD integrated for login. This was working perfectly before upgrade. Any idea how this can be resolved?

  • Check out this thread: https://github.com/jupyterhub/jupyterhub/issues/1405 – jlewkovich Mar 15 '19 at 01:01
  • Thanks for the pointer. However, is it possible to do this for multiple users? As i mentioned, we are integrated with AD for login. I'm not sure if we can do the mapping for all users. – user3629042 Mar 15 '19 at 07:55
  • This is the python output for getpwnam. `python3 -c 'import pwd; print(pwd.getpwnam("test"))' ` `pwd.struct_passwd(pw_name='test', pw_passwd='*', pw_uid=970361581, pw_gid=970297513, pw_gecos='test', pw_dir='/home/test', pw_shell='/bin/bash') ` – user3629042 Mar 19 '19 at 16:27
  • I think the issue is that all my AD users are in UPPER CASE. But the logs show the users in lowercase. Even the pwd.getpwnam module has failed when the case is not correct. – user3629042 Mar 19 '19 at 17:16
  • We were able to overcome this by commenting `#username = username.lower()` in `/usr/local/python3/lib/python3.4/site-packages/jupyterhub/auth.py ` – user3629042 Mar 21 '19 at 09:33
