Snapd desinstalado com aplicativos do sistema principal

Question

Depois de instalar o Ubuntu 18.04, notei um tráfego de alta largura de banda com o processo snapd e, como não uso os aplicativos de encaixe, decidi remover o snap.

Eu usei este comando $ sudo apt purge snapd ubuntu-core-launcher squashfs-tools

e esta é a saída

Percebi que ele removeu os principais aplicativos do sistema. Como posso desfazer o processo novamente para restaurar o snap e os aplicativos novamente?

obrigado antecipadamente

Se você erroneamente desinstalar os pacotes principais em um sistema Ubuntu, é possível colocar os pacotes deb de volta simplesmente com um comando: -

Nota : Presume-se que você tenha instalado previamente o produto Ubuntu, e não um dos outros sabores.

sudo apt install ubuntu-desktop^ 

Quando o snapd for reinstalado (o que deve ser feito com o comando acima), você poderá reinstalar os snapshots pré-instalados com: -

sudo snap install gnome-calculator
sudo snap install gnome-characters
sudo snap install gnome-logs
sudo snap install gnome-system-monitor

Simplesmente repita esse processo ou use o software gráfico Ubuntu para os snaps adicionais, como communititheme , vlc e outros.
