Installation fails on Raspberry Pi 4 / cleanup does not remove apt repo(?)

[Pfeil]

Describe the bug

Installation does not work on a Raspberry Pi 4. Probably on ARM devices in general. After installation cleanup, if leaves a non-working apt repo for MongoDB non-arm devices. (Although I can not guarantee this hasn't been there before, I think this is not a coincidence)

Context

• Hardware: Raspberry Pi 4
• YunoHost version: 4.3.6.3
• I have access to my server: Through SSH && through the webadmin
• Are you in a special context or did you perform some particular tweaking on your YunoHost instance?: no
• Using, or trying to install package version/branch: default

Steps to reproduce

• Install overleaf from the web interface on a Raspberry Pi 4. (or sudo yunohost app install overleaf)
• Configuration is almost the default (anonymous access = yes, language = en)

Expected behavior

• Either install the app or tell the user that it is not ARM compatible.
• On failure, remove apt repo of e.g., MongoDB if this installation added it (proper cleanup).

• I wanted to see if the issue was a missing apt update and found this:

  $sudo apt update

  N: Skipping acquire of configured file 'main/binary-armhf/Packages' as repository 'http://repo.mongodb.org/apt/debian buster/mongodb-org/4.4 InRelease' doesn't support architecture 'armhf'

  It seems that this apt repo of MongoDB is simply not compatible with arm? This guide seems to be official and up-to-date on how to do it on ARM (on Ubuntu): https://www.mongodb.com/developer/products/mongodb/mongodb-on-raspberry-pi/

I did experienced the same issue on Raspberry pi3+ which is not installing due to mongodb issue. Here are the logs : https://paste.yunohost.org/raw/umomoyafec

On failure, yunohost also fails to uninstall overleaf-ynh-deps
