Since the release of Mageia 6 last week, there have been several reports about issues with upgrades from Mageia 5, particularly for users upgrading from KDE 4. While that is not surprising due to the complex nature of the upgrade from KDE 4 to Plasma 5, those issues had sadly not been noticed by our QA team during its extensive pre-release testing.
We want to both acknowledge that we are aware of the issues and working on needed fixes, and make sure that those wanting to upgrade from Mageia 5 are aware of the issues and read the errata beforehand. To avoid bad surprises for the least tech savvy users, we temporarily disabled the upgrade notification that prompts users to upgrade to Mageia 6 from their live session – it will be re-enabled as soon as we are confident that most users will have a smooth upgrade.
Also note that these issues are not present on new installs and the installation experience, particularly switching from KDE 4 to Plasma 5, will be easier with a fresh installation. As such all upgrade issues should be fixable via normal package updates, and no new ISOs are planned.
The section in the Mageia 6 errata relating to upgrades highlights the procedure to minimize some of the known issues. A big thing to note that has caused issues is the use of third party packages installed in Mageia 5, especially NVIDIA graphics drivers from the upstream website (as opposed to the ones packaged by Mageia).
Here is a small summary of things to look out for:
- Upgrading from KDE 4 with mgaonline may lead to a broken display, so users don’t know the results of the upgrade, and may reboot with a non working system.
- Graphics drivers are also an issue, especially NVIDIA. Several users are faced with an endless loop issue.
A note on upgrades in general – performing the upgrade offline with the Classical ISO works only if update repositories are enabled, as a full Mageia 5 upgrade requires more packages than are available on the ISO images. The recommended way to start an upgrade is to do it from a non-graphical terminal (e.g. tty2 accessed via Ctrl+Alt+F2) using urpmi, as outlined in the release notes.
Apart from those upgrade issues affecting some Mageia 5 systems, most users seem to be pretty happy with Mageia 6 – we will continue showcasing some of the interesting developments made for this release in future blog posts.
