Mail app missing in store

🚧 Installation
1

I am relatively new to Nextcloud. I have just installed Nextcloud on a NUC using docker-compose with a postgres DB. I am using Traefik2 as a reverse proxy (There are still some security warnings related with the proxy that I haven’t fixed yet). The installation went well and I haven’t encountered any major issues. I see the app store and can install apps. However, the mail app is for some reasons missing in the store and I can’t find a reason why. Other Nextcloud Apps like Calendar, Tasks, Contacts are installed. Do you have ideas?

Thanks for your help! The Mail app is actually the main reason why I started with Nextcloud.

Below some more detailed information:

Nextcloud version: 20.0.6
Operating system and version: Ubuntu 20.04 + docker compose on a NUC i5
Apache or nginx version: not quite sure, nginx not installed
PHP version: 7.4.14
DB:pgsql Version: PostgreSQL 13.1 (Debian 13.1-1.pgdg100+1) on x86_64-pc-linux-gnu
DNS: 127.0.0.11

I have used the following docker-compose script. I tried to reinstall Nextcloud a couple of times but don’t see a difference.

Here is (the relevant lines) of my docker compose file

This folder is not mounted by docker and therefore a bit trickier to access. If necessary, I will look at the data for you.

That’s a bug with php version comparison. See: Mail app not available for installation · Issue #4383 · nextcloud/mail · GitHub
