Removed the app running on basedomain.tld same restore issue with the permission is there any way im getting back my server without loosing absolutely everything ?

[jukefr]

Seems like this is an issue that happens often.... https://forum.yunohost.org/t/solved-solution-synapse-upgrade-from-1-38-to-1-42-failed-backup-restore-failed-too/17406 I feel like there should be some sort of way to handle having an app running on the base domain without making every thing break on updates ? At the very least there could be warning before making the install a completely unusable state (for most users that will not know how to fix this)

[jukefr]

fyi the way to fix this

1. remove any synapse install leftovers
2. reinstall fresh synapse (it will fail immediatly)
3. delete this fresh install (it should see the leftovers from previous install now)
4. now apparently you can restore the backup..............................

also this entire process seems to have broken mautrix_whatsapp...

I just ran into the same problem.

@jukefr What "install leftovers" did you remove to get it up and running again?

Actually, my issue was not linked to any permissions but to some python OpenSSL libs being included in the backup as reported here (also, their fix worked for me!): https://github.com/YunoHost-Apps/synapse_ynh/issues/355
