Apt Update Vs Apt Upgrade Differences Explained Source: man apt clone. apt clone is used by ubiquity (ubuntu installer) for upgrade process. it is much better than the dpkg get selections solution because: it preserves all repositories information. it keeps track of what packages were automatically installed. it allows to repack locally installed deb files. That's why i'd suggest always using apt cache policy <package name> instead. note about output: i have some local repository setup and both of the command shows those as well. note 2 newer apt comes with policy integrated into them. so, you can use apt instead of apt cache directly. The reason for this change is that when adding an openpgp key that's used to sign an apt repository to etc apt trusted.gpg or etc apt trusted.gpg.d, the key is unconditionally trusted by apt on all other repositories configured on the system that don't have a signed by (see below) option, even the official debian ubuntu repositories. Use this: sudo apt update # fetches the list of available updates sudo apt upgrade # installs some updates; does not remove packages sudo apt full upgrade # installs updates; may also remove some packages, if needed sudo apt autoremove # removes any old packages that are no longer needed.
