system update list `Not upgrading` packages

[lucarin91]

The system update command lists also packages, that will fail to upgrade. This is due to the use of apt list --upgradable which doesn't check if a package could be installed. Differency from the apt-get update or apt update commans.

arduino@asdasdasd:~$ sudo apt upgrade
Not upgrading:
  alsa-ucm-conf

arduino@asdasdasd:~$ sudo apt list  --upgradable
alsa-ucm-conf/stable-backports 1.2.16.1-1~bpo13+1 all [upgradable from: 1.2.14-1qcom0.1arduino3]
arduino-app-cli/unstable 0.13.0-rc.10 arm64 [upgradable from: 0.12.1]
arduino-app-lab/unstable 0.10.0-rc.4 arm64 [upgradable from: 0.9.0]
....

This will cause a crash of the update if some packages have missing dependencies or other issues. For instance:

$ arduino-app-cli system update
...

[log] Some packages could not be installed. This may mean that you have
[log] requested an impossible situation or if you are using the unstable

[log]
[log] The following packages have unmet dependencies:
[log]  alsa-ucm-conf : Depends: libasound2t64 (>= 1.2.15) but 1.2.14-1 is to be installed
[log] E: Unable to correct problems, you have held broken packages.
[log] E: The following information from --solver 3.0 may provide additional context:
[log]    Unable to satisfy dependencies. Reached two conflicting decisions:
[log]    1. alsa-ucm-conf:arm64=1.2.16.1-1~bpo13+1 is selected as an upgrade
[log]    2. alsa-ucm-conf:arm64=1.2.16.1-1~bpo13+1 Depends libasound2t64 (>= 1.2.15)
[log]       but none of the choices are installable:
[log]       - libasound2t64:arm64=1.2.16.1-1~bpo13+1 is not selected for install
[restarting] Upgrade completed. Restarting ...
Terminated

A possible solution is to run a siumilatuon of the upgrade and get all the packages that will be actually install after the simulation.

As a bonus feature of using the update similation is that we can get select to upgrade only the package that are in our repository (i.e., Arduino:)
