Thanks a lot, rasmu! That did the job! Now the update was succesful!
Glad you’d figured it out
Actually, I got the same issue while upgrading to 6.3.4
The steps above are I guess mandatory but did not worked for me.
urlib3 installed the 1.24 version which seems not compatible. The fix is to force 1.23 version installation.
sudo pip install --upgrade pip
sudo pip install -I urllib3==1.23
My Seafile is back
No need to upgrade Rasbian (I am on Jessie)
Of course you need. Jessie is LTS, Debian “Stretch” 9 is stable, and Buster will be released in march. Since dis-upgrades ca fuck up the system you should make now the step to Debian 9 and then in march to Debian 10. Otherwise you’#ll never upgrade until you got hacked because you used an unsupported OS version.
