Я даже не открыл магазин ubuntu-software, когда он появился. Есть ли способ, которым я могу избежать этого? Кроме того, если я удалю пакет Snap-Store, смогу ли я устанавливать приложения Snap с помощью терминала?
You can safely uninstall the Snap Store app, and if you do you will still be able to install snap apps from the terminal with sudo snap install package-name
and also to manage installed snap apps from the terminal.
Your RAM usage for the snap-store and gnome-software seems unusually high. My RAM usage for gnome-software is 1.4 MiB even if the app isn't open. My RAM usage for snap-store is 0 if the app isn't open, and 4.0 KiB if the Snap Store is open. To release memory from the cache run echo 3 | sudo tee /proc/sys/vm/drop_caches
