ubuntu:apt:update_the_package_database
Ubuntu - apt - Update the package database
apt works on a database of available packages.
- If this database is not updated, the system will not know if there are newer packages available or not.
- Like the regular apt-get update with color output enabled, but apt update also shows the number of upgradeable packages (if any).
sudo apt update
returns:
[sudo] password for peter: Hit:1 http://je.archive.ubuntu.com/ubuntu jammy InRelease Get:2 http://je.archive.ubuntu.com/ubuntu jammy-updates InRelease [119 kB] Get:3 http://je.archive.ubuntu.com/ubuntu jammy-backports InRelease [108 kB] Get:4 http://je.archive.ubuntu.com/ubuntu jammy-updates/main amd64 Packages [721 kB] Get:5 http://je.archive.ubuntu.com/ubuntu jammy-updates/main i386 Packages [430 kB] Get:6 http://je.archive.ubuntu.com/ubuntu jammy-updates/universe amd64 Packages [927 kB] Get:7 http://security.ubuntu.com/ubuntu jammy-security InRelease [110 kB] Hit:8 https://ppa.launchpadcontent.net/kisak/kisak-mesa/ubuntu jammy InRelease Hit:9 https://repo.radeon.com/amdgpu/5.4.6/ubuntu jammy InRelease Hit:10 https://repo.radeon.com/rocm/apt/5.4.6 jammy InRelease Fetched 2,415 kB in 11s (228 kB/s) Reading package lists... Done Building dependency tree... Done Reading state information... Done All packages are up to date.
NOTE: Three types of lines are shown: Hit, Get, and Ign.
- Hit: There is no change in the package version.
- Ign: The package is being ignored.
- There could be various reasons for that, including:
- The package is so recent that it does not even bother to check for a new version.
- There was an error in retrieving the file but error was trivial and thus it is being ignored. This is not an error. There is no need to be worried.
- Get: There is a new version of the package available.
- apt-get will download this information (not the package itself).
