yes, just after the upgrade. System did not report issues at the time, but borg never worked again, even tried to reinstall from backup. I can install borg package from debian repo and read/access to saved borg backups, but I’ve lost integration with YNH, the main reason I had chosen borg_ynh package.
I’ve posted in the Borg thread but nobody could help me with this issue, so I’ve changed to restic. Yes, it seems to be a python problem in my system. Unfourtunatly I’m just enthusiastic about selfhosting, but I don’t have a technical background to fully understand how borg/python work so I can not afford to experiment myself.
Many thanks for your interest
