(Sorry for the inconvenience)
pc-updatemanager is the command line equivalent to Update Manager. It can be used to apply system updates and to perform an operating system upgrade. It can also be used to update packages, providing a command line equivalent to the "Package Updates" tab of Package Manager.
If you type pc-updatemanager, it will show its available options:
/usr/local/bin/pc-updatemanager - Usage ---- branches - List available system branches chbranch <tag> - Change to new system branch check - Check for system updates install <tag>,<tag2> - Install system updates pkgcheck - Check for updates to packagespkgupdate - Install packages updates
To determine if newer versions of packages are available, type the following command as the superuser.
pc-updatemanager pkgcheck Updating repository catalogue Upgrades have been requested for the following 253 packages: list of packages snipped The upgrade will require 70 MB more space 439 MB to be downloaded To start the upgrade run "/usr/local/bin/pc-updatemanager pkgupdate"
In this example, newer versions are available for 253 packages. The list of package names was snipped from the sample output. If no updates were available, the output would have instead said "All packages are up to date!".
If updates are available, you can install them with this command:
pc-updatemanager pkgupdate Updating repository catalogue snip downloading and reinstalling output
While the output has been snipped from this example, the update process will download the latest versions of the packages which need updating, displaying the download progress for each file. Once the downloads are complete, it will display the reinstallation process for each file.
