Kde4 Plasma5 Upgrade

From Funtoo
Jump to navigation Jump to search

This page is under development. Tassietux (talk) 05:51, January 31, 2017 (MST)

KDE Plasma 4 development and support has ceased. KDE Plasma 4 ebuilds are currently masked upstream and are due to be removed from the Portage tree during February 2017.

This change will affect Funtoo Linux.

Plasma 4 was the graphical environment that formed part of the former KDE SC 4 (KDE Software Compilation 4). Plasma 5 is the current graphical environment offered by KDE. Many of the KDE Applications available under KDE SC 4 continue to be available under Plasma 5.

The purpose of this page is to detail the steps required to migrate Funtoo Linux from KDE SC 4 (Plasma 4) to KDE Plasma 5 and KDE Applications. Given incompatibilities between Plasma 4 and Plasma 5 packages, Users undertaking this process are likely to encounter one or more blockers. Users are encouraged to seek assistance in the #funtoo IRC channel on Freenode.

Update Funtoo Profiles

Changes to Funtoo mix-in Profiles are required for KDE Plasma 5. Review the selected profiles using epro.

root # epro show

=== Enabled Profiles: ===

        arch: x86-64bit
       build: current
     subarch: intel64-haswell
      flavor: desktop
     mix-ins: kde

There are two KDE-related mix-ins available in Funtoo: kde and kde-plasma-5. To migrate to KDE Plasma 5, users must remove the kde mix-in and add the kde-plasma-5 mix-in.

DO NOT combine kde and kde-plasma-5 at the same time - they are incompatible.

root # epro mix-in -kde +kde-plasma-5

=== Enabled Profiles: ===

        arch: x86-64bit
       build: current
     subarch: intel64-haswell
      flavor: desktop
     mix-ins: kde-plasma-5

>>> Removed kde mix-in.
>>> Added kde-plasma-5 mix-in.

Review USE Flags

To achieve clean update it is necessary to review /etc/portage/package.use, /etc/portage/make.conf for a kde sc4 specific USE's. Having this USE flags enabled globally or per package base may clash with default kde-plasma-5 mix-ins settings and may result in certain difficulties with update, such as ebuild blocks.

Following command will scan your /etc/portage/make.conf

root # grep -e "qt[[:digit:]]" -e "handbook" -e "kde" -e "plasma" /etc/portage/make.conf

It is necessary to review these USE's, if set. Next commands will scan your /etc/portage/package.use

root # grep -e "qt[[:digit:]]$" -e "qt[[:digit:]] " -e "handbook$" -e "handbook " -R /etc/portage/package.use
root # grep -e "kde$" -e "kde " -e "plasma$" -e "plasma " -R /etc/portage/package.use

Like above it's needed to review USEs, if set.
