Upgrade impossible

Hello,

I can’t upgrade Nextcloud. I use the updater but it freeze at the backup step or “Verifying integrity” step

Nextcloud version (eg, 20.0.5): 19.0.12 to 20.0.10
Operating system and version (eg, Ubuntu 20.04): Debian 4.9.2-10+deb8u1 but, it’s a virtual serveur
Apache or nginx version (eg, Apache 2.4.25): I do’nt have this information
PHP version (eg, 7.4): 7.4

The issue you are facing:

Is this the first time you’ve seen this error? (Y/N): N
I tried several times
