[SOLVED] Upgrade from 6.2.5 to 6.3.1 ImportError: cannot import name DependencyWarning

schneimi · July 7, 2018, 11:53am

The upgrade script was successful, but I get an Internal Server Error 500 on access in browser.

Running Seafile with Docker (Hypriot v1.8.0) on RPI3B+ and the following packages

FROM sdhibit/rpi-baseimage    
RUN apt-get update && apt-get install -y \
        python2.7 \
        python-setuptools \
        python-simplejson \
        python-imaging \
        python-memcache \
        python-mysqldb \
        python-requests \
        python-urllib3 \
        libpython2.7 \
     && rm -rf /var/lib/apt/lists/*

I tried to update the packages python-urllib3 and python-requests, but already using the latest.

Here are the logs, any ideas?

exact same problem here.

klangborste · July 7, 2018, 9:06pm

I fixed it with:

apt-get remove python-pip
easy_install pip
sudo pip install --upgrade urllib3

Stop Seafile
rm -rf /<tmp_dir>/seahub_cache/
Start Seafile

…worked for me

I use Debian 8. Found some part of the solution here https://stackoverflow.com/questions/27341064/how-do-i-fix-importerror-cannot-import-name-incompleteread, here https://stackoverflow.com/questions/44927351/importerror-cannot-import-name-dependencywarning and here https://github.com/nickoala/telepot/issues/80#issuecomment-269206431

Thx for your input, this solved the problem.

Installing collected packages: urllib3
  Found existing installation: urllib3 1.9.1
    Uninstalling urllib3-1.9.1:
      Successfully uninstalled urllib3-1.9.1
Successfully installed urllib3-1.23

I additionally had to apt-get install openssl to make the urllib3 upgrade work.

But I still struggle with the update as two more problems came to light. But that should not be part of this thread.

For all people out there who have mulitple python instances running (like me with 2.7 which is needed by seafile/seahub & 3.4 for other things) a little hint:

I needed to upgrade urllib3 & chardet special for python 2.7. That worked like this:

seafile@XXXX:~/seafile-server-latest$ sudo python2.7 -m pip uninstall urllib3
Uninstalling urllib3-1.9.1:
  /usr/lib/python2.7/dist-packages/urllib3
  /usr/lib/python2.7/dist-packages/urllib3-1.9.1.egg-info
Proceed (y/n)? y
  Successfully uninstalled urllib3-1.9.1
seafile@XXXX:~/seafile-server-latest$ sudo python2.7 -m pip install urllib3
Collecting urllib3
  Cache entry deserialization failed, entry ignored

Installing collected packages: urllib3
Successfully installed urllib3-1.23
seafile@XXXX:~/seafile-server-latest$ sudo python2.7 -m pip uninstall chardet
Uninstalling chardet-2.3.0:
  Would remove:
    /usr/lib/python2.7/dist-packages/chardet
    /usr/lib/python2.7/dist-packages/chardet-2.3.0.egg-info
Proceed (y/n)? y
  Successfully uninstalled chardet-2.3.0
seafile@XXXX:~/seafile-server-latest$ sudo python2.7 -m pip install chardet

Installing collected packages: chardet
Successfully installed chardet-3.0.4

After that and a reboot everything went well.

Another important thing is to exactly upgrade urrlib3 to version 1.23 (via sudo pip install --upgrade urllib3==1.23) (see Seahub/Seafile Update ends up with an "ImportError: No module named ordered_dict" )
