The difference between apt upgrade and apt full-upgrade is primarily in how they handle package dependencies and changes:
-
apt upgrade:- Upgrades all currently installed packages to their latest versions.
- Does not remove any packages or install new packages that may be required due to dependency changes.
- If a package upgrade requires the removal of another package, it will not proceed with that upgrade.
-
apt full-upgrade:- Also upgrades all currently installed packages to their latest versions.
- Can remove existing packages if necessary to resolve dependencies.
- May install new packages that are required for the upgrades to succeed.
In summary, apt full-upgrade is more comprehensive and can handle situations where package dependencies change significantly, while apt upgrade is more conservative and avoids removing packages.
