The issue you are facing:
After upgrade to NC 20.0.6, the mail app will not upgrade (webgui). Then after removing the mail app using webgui and attempting reinstall, mail app is not found. Then attempting to install the mail app from cli, I get a not found error:

sudo -u www-data php occ app:install mailError: Could not download app mail

Is this the first time you’ve seen this error? Y

Steps to replicate it:

  1. Update from NC 20.0.5 to 20.0.6 with mail app 1.7.X installed
  2. Attempt to upgrade the mail app to 1.8.X using web
  3. or attempt to install the mail app using occ

Same issue here.

The app is disabled during the upgrade. After, there’s no option to enable or download&install it.

Some other apps where also disabled during the upgrading. Some of them where enabled back but others, like Mail or Analytics (wich are compatible with v20 and v21) cannot be enabled again.

I confirmed, before performing the upgrade, that all apps where upgradable, but it seems they were not.
