Description of my issue

Not able to run migrations to finish update to Bullseye. I have shared the logs below…

Mostly ffsync is blocking the migration as it is built using python2 which is not anymore available on bullseye

Any suggestions on what next steps I can take to solve this problem? I never had this issue with yunohost upgrades. This is the first time

[Aleks]

Unfortunately regarding ffsync there is no alternative but to remove the app

FFsync has been unmaintained by Mozilla for years, and Python 2 really is quite deprecated too

You must uninstall ffsync to perform this migration.
Then once under Yunohost 11 install ffsync, it will work.
I did it this way.

Thank you @Aleks and @mib for your support!! I was able to successfully migrate to the new version
