Is it enough for snap to use sudo pacman -Rscn snapd or there is something else that is related to snapd that should also be removed? A service, process or some other hidden package? I see someone mentioning about apparmor is related to snapd.
I want to remove flatpak as well.
I am not sure about AppImage*, and if there is some package installed to make it "work".
I am aware that unfortunately Manjaro is shipping snap and flatpak... Apparently, everyone is giving in to Canonical's and Red Hat's wishes. Hasn't systemd been enough?
I also do not use any of these, but I feel some points need a little bit of additional information.
AFAIK, only the 18.1 iso series will ship snapd installed by default. Any older has snapd not installed by default. I am not aware of flatpak or appimage installed by default in any version. You just have the option to install them, but you have to install them yourself.
To remove the snap support services for 18.1 series see:
AFAIK apparmor is required by snapd for sand-boxing
It is not like "living in the past", it's more like "using what works better", that is = Repos.
I have already used and tested both snap and flatpak and have had more cons than pros with them, so I decided keep using so hated 'old way' of doing things. That's it.
When snap and flatpak became more mature and less problematic, maybe I'll give them a second chance.
