[07:35:39] <Simon Mellerin 🐨> Hi everyone, I have a small question about application backup and restore.

I tried to upgrade nextcloud and it failed. And the restore seems to not have been done correctly. The app is broken.

But my question is a bit more generic. Yunohost sees nextcloud as installed, and when I go to the backups panel and tried to restore a previous backup of nextcloud, web admin tells me that : "Les applications suivantes ne peuvent pas être restaurées car elles sont déjà installées : nextcloud"

It seems a bit odd for me, does this mean that I have to first uninstall the app to be able to restore it ?

Thanks

[07:54:17] <artlog> yunohost backup is not only data, this is application version too, so yes a restore is somehow more like an install with a backup.
[07:54:18] <artlog> there is no such thing as restore an older backup on a new version, the way to do is to upgrade. If it fails, what is your case, then... well you are at teh right palce
[07:54:21] <artlogmatrix> Simon Mellerin 🐨: nextcloud upgrade failing is quite common since it is so easy to install many app in nextcloud... did you try to find some information in forum or even open a topic ? like https://forum.yunohost.org/t/nextcloud-doesnt-run-after-unsuccessful-upgrade/42062/2
[07:54:25] <artlog> current trend for php based application failures is around sury packages versions https://forum.yunohost.org/t/yarn-and-sury-apt-keys-issues/41617
[07:55:49] <Simon Mellerin 🐨> Thanks for your answer, I haven't dig in more for now, I wanted to understand this backup thing first 🙂
[07:58:50] <Simon Mellerin 🐨> I'm gonna look at your links thanks
