apt update vs apt upgrade vs do upgrade vs release upgrade
apt update refreshes repository indexes.
ex: if you added a new repository or dependency
then you type apt install
it doesn’t installs the package.
because linux system has to fetch & know the source.
we need to run update.
update nothing to do with existing packages. just it refreshes the sources.
ex: installed php 7.4.1
then new version available with same dependency
7.4.2
if we run apt update command it fetches. 7.4.2
then the upgrade command
upgrades the existing php-pfm package
from 7.4.1 to 7.4.2
not from major version 7.4 to 7.5
upgrade command without update command is useless.
apt-get dist-upgrade vs apt full-upgrade vs apt upgrade
apt-get dist-upgrade will install or remove packages as necessary to complete the upgrade, apt upgrade will automatically install but not remove packages. apt full-upgrade performs the same function as apt-get dist-upgrade .
