  1. The kubuntu-plasma5-desktop package doesn’t seem to exist for me.

  2. no kubuntu-plasma5-desktop package :(

  3. Upgraded to 5.2 but went back to Ubuntu Gnome. Plasma 5.2 is far from stable!
    * File-manager is very unstable when viewing / opening / editing files on a NAS station.
    The file manager keeps crashing when enabling / disabling the preview mode. Sometimes i cannot connect to the station. Requires a reboot.
    * The ‘hot corner’ feature is very buggy. It works, or it doesn’t work. Sometimes nothing happens and after a restart it works again.
    * The desktop is toasting my Nvidia Graphics card. Temperature often gets to 60 degrees Celsius, while in Ubuntu it keeps at around 33. Not sure whats going on here.
    * And a lot more issues…!

  4. I agree with Danny!
    The new Plasma 5 desktop isn ‘t stable enough and brings a lot of problems. Do not upgrade if you need a well working system. In my case (Kubuntu 14.10) the (next) booting process stopped with Plasma 5 after running the filemanager (dolphin) as root. No chance to run the x-server. Perhaps it is a problem with Nvidia Graphics cards. So I had to cancel the system and return to Plasma 4…. I hope that the KDE People fixed these heavy bugs in the next versions.

    • @Wolfgang ,,,,,,,, you do not run dolpin as root (it is shure to hijack the ownership/permitions of your files and posablie ~/.Xauthority as well , and you will be locked out of your login.

      if you must run as root use “kdesudo dolphin” and not just sudo or starting from a root shell .


  5. After I update Kubuntu 14.10 ( kubuntu-devel-release-upgrade ) to 15.04 through run command, and then, I got some problems arised :-
    1) update manager not opened
    2) kubuntu-devel-release-upgrade did not working in run command
    3) USB Modem device not detecting
    4) Not installing softwares through software center

    Please rectify the corrections for further KDE Plasma new version ( Include Media support, with beautiful look )
