Hi, I cannot upgrade Nextcloud to version v210624280 .
System:2110141091
Installer:210929152
Hardware: HC4

Here follows what happens. Ideas or suggestions are welcome, thanks.

Steps to reproduce the error

  • through web interface: nothing happens but I can create backups of the app ;

  • through Putty (console):

root@syncloud:~# sudo snap refresh nextcloud

What is your current version of Nextcloud?
If you skip one major version update you need to upgrade one by one using this instruction:

According to the guide I have to run commands from 21 to the end. The first command fails: it cannot resolve the address:

I see, looks like nextcloud database is corrupted or not enough disk space.

What kind of boot disk are you using (where syncloud image was written)?

If you have a backup (Settings - Backup) you could restore that backup into a fresh install of Nextcloud (of the same version as backup) and then continue the upgrade.

If you have no backup you can remove Nextcloud and install again from the store but you will lose settings like contacts/calendar. Files are stored separately on disk and can be rescanned back into Nextcloud if you have the same username using this command:

Hi Boris,
thanks a lot. I have solved with a fresh install of Nextcloud. I wasn’t aware that the archive is not impacted by it! I seized the opportunity to perform a complete reset and now I am much happier of its configuration than before. Thanks a lot. Ciao
