For me upgrading still doesn’t work with Yunhost 11.2.26.
Still error in backup procedure:
Info: Declaring files to be backed up...
Warning: /var/cache/yunohost/app_tmp_work_dirs/app_yyb4onoh/scripts/backup: line 34: phpversion: unbound variable
Error: Could not back up privatebin
Side question: Is there a way to exclude an app from upgrade procedure without uninstalling it. At the moment the bug blocks several other apps from upgrading.
I reinstalled privatebin and it works now with the new versions.
Sorry for bothering. I thought it was a script problem but obviously something was broken on my side.
