Update Leap with KDE 5.8.8

I have a doubt, my opensuse leap with KDE is with version 5.8.7, and already it was released to 5.8.8 and it is possible to do the update in leap?

Not 100% sure but Plasma doesn’t automatically get updated with Leap. As with the Fedora Plasma spin there may or may be no point releases. As far as I know Leap runs some form of customised plasma so things work a bit differently. If you are not experiencing bugs there is hardly a need to try installing it manually.

LEAP is a stable distribution it doesn’t get software upgrades however bug fixes stability and security fixes get back ported in the update repo
but if you want the latest LTS release you can get it from the KDE:/Frameworks5:/LTS reposetory
https://download.opensuse.org/repositories/KDE:/Frameworks5:/LTS/openSUSE_Leap_42.3/
it currently has plasma 5.8.8 LTS
you’d need to add the above repo and do a full vendor change to it

zypper ar -f https://download.opensuse.org/repositories/KDE:/Frameworks5:/LTS/openSUSE_Leap_42.3/KDE:Frameworks5:LTS.repo
zypper dup --from http://download.opensuse.org/repositories/KDE:/Frameworks5:/LTS/openSUSE_Leap_42.3/

I do not recommend this as all fixes will be released as updates from the update repo and adding an extra repo and doing a fill vendor change to it might break something if you don’t know what you’re doing

Can’t agree enough on this. It’s not worth it. If there are important bug fixes and security upgrades they will get back ported. On another note have you tested Tumbleweed to see how that works for you. I was also skeptical about going onto a rolling-type distro but its awesome. With the ability to rollback and regular backup of your files there is really little to worry about.

If one were to add the above repository (with vendor change), and experienced undesirable consequences, could the remedy be to remove the added repository and to a zypper dup ?

yes you can allway do a zypper dup with the main + update repo but there is no real reason for adding this repo under leap
that’s more for TW users who want to use plasma lts

It seems that the migration to the KDE Plasma5 LTS is a tad more complicated. Adding only the KDE “Frameworks” repository introduces an almost uncountable number of conflicts, most associated with “libQT5score”, and some others.

To resolve these conflicts requires the addition of the QT5 repository (download.opensuse.org/repositories/KDE:/Qt5/openSUSE_Leap_42.3/). At that point, one will spend a LOT of keyboard time selecting option #2 to install some updated QT5 package. Of course, one could zypper in the QT5 repository first.

Frankly, it is a tad of a challenge, and could be messy.

I wasn’t sure if the updated Qt5 repo was needed for lts but I guess it was you also need KDE:/Qt5
http://download.opensuse.org/repositories/KDE:/Qt5/openSUSE_Leap_42.3/
again I’m not sure about the applications repo as plasma 5 is the desktop only you might need KDE:/Extra
http://download.opensuse.org/repositories/KDE:/Extra/openSUSE_Leap_42.3/

zypper ar -f http://download.opensuse.org/repositories/KDE:/Qt5/openSUSE_Leap_42.3/KDE:Qt5.repo
zypper ar -f http://download.opensuse.org/repositories/KDE:/Extra/openSUSE_Leap_42.3/KDE:Extra.repo

and then you need to do

zypper dup --from <KDE:LTS> --from <KDE:Qt5> --from <KDE:Extra>

replace <KDE:LTS> with the repo URL or repo name or repo alias or repo number (do this for all 3 repos)
just keep in mind upgrading Qt5 will break non kde applications that use Qt5 (parts of lxqt will definitely break)
and if you’re upgrading Qt5 why go for LTS why not install plasma 5.11
http://download.opensuse.org/repositories/KDE:/Frameworks5/openSUSE_Leap_42.3/
the process is the same do a zypper dup --from …

ps
that’s another reason to stay with the plasma 5 from the update repo all bug fixes will be ported back changing Qt libraries is risky and unnecessary for LTS

edit
there is a good wiki about the kde repositories including lts releases
https://en.opensuse.org/SDB:KDE_repositories#Long-Term-Support_Frameworks_and_Plasma

The LTS update was not that much different , so …

I took your suggestion to go to plasma 5.11.? … the zypper update went uneventful, except for for downgrades …

One word: Wow! Tear problem gone, swap usage plunging, and … (wait for it) …

much quicker!!!
