Snap is a software deployment and package management system originally designed and built by Canonical, the company behind the for the Ubuntu phone operating system. After the fall-down of that last one, the Snap system was brought to desktop and updated to work across a range of Linux distributions as independent upstream software deployment system. But, all that glitters is not gold.
I’m not alone: on the Ubuntu communities, on the social networks, on Reddit (The snap experience is
The overall user experience with snaps on Ubuntu 18.04 LTS (obviously, in my case!) is frustrating: several apps won’t start when installed as snaps, others run weird, others take really long time to start. As an example: Telegram as snap takes around 51 sec to be operative, Telegram installed as binary starts in 1,5 sec.
So, for now, I can live without Snap and snaps.
$ sudo apt autoremove --purge snapd gnome-software-plugin-snap
$ rm -fr ~/snap
This will completely remove the Snap sub-system (AskUbuntu related answers here), all the installed snap packages, all the related data, and it never again suggests snap packages in the Ubuntu (or GNOME) software store.
As alternatives to Snap, you can use AppImage or FlatPak format. If you need to confine apps, you can use AppArmor, sandbox, or container technologies. At this time, Snap needs to be more reliable, stable and fast.
For me, it worked and now the system is fast and responsive as it had never been. You should also try to stay without Snap for a period and see what will happen!
