Sounds like https://github.com/nextcloud/server/issues/25137

Up. Same here - Nextcloud 20.0.5.

Looks like I am affected as well, also on Nextcloud 20.0.5 fresh installation

@ChristophWurst

Thank you for suggesting this, I applied the fix mentioned, but it seems to have no effect, unfortunately

PHP version: 7.3.19-1

Do all of you use a php version like that, e.g. with the hyphen at the end?

[GabrieleV]

Fix applied, nothing changed.

Something interesting. After fresh install it does not appear. Few days later it's on the store. Changes i have made since then ( installation ) are to enable opcache and redis ( may not be relevant ).

[GabrieleV]

Fresh installed 9 days ago, mail app never appeared.
I've enabled opcache too, not redis.

Just upgraded to 20.0.6 and now the mail app is listed ...

[ChristophWurst]

Looking at https://github.com/nextcloud/server/commit/bedd9acf7874b836bef224989c2ce7f5e3b0a2fa I think we now do version comparisons wrong. PHP's version_compare will return false for version_compare('7.4.14', '7.4', '<='). But if the app says it's compatible with 7.4 then 7.4.14 is totally fine. 7.4 shouldn't be expanded to 7.4.0. I'll see how we can fix this.

[ChristophWurst]

Patch is at https://github.com/nextcloud/server/pull/25335. Please let me know if that helps.

[GuillaumeAmat]

@ChristophWurst It doesn't seem to do the job for me :/

[ChristophWurst]

@GuillaumeAmat any more info? Are you sure your server didn't just use a cached version of the filtered response? Check again now if my patch is still applied.

[GuillaumeAmat]

Oh you're right it's working now 👌 Thanks for the cache tip
