I've installed Ubuntu mate 14.04 5 days ago and now i want to shift back on Lubuntu.instead of downloading entire lubuntu 16.04 lts,can i just upgrade my Ubuntu mate to lubuntu as both are Ubuntu with different desktops?if yes then how?or should i just download lubutnu 16.04, which is better?

  • Do a clean install of Lubuntu. If you just upgrade, you'll upgrade to Ubuntu Mate. There's no way to switch flavors while upgrading that I know of. – DK Bose May 17 '17 at 08:35

You can just upgrade to 16.04 and then change your desktop manager. sudo apt-get install lubuntu-desktop should do the trick to install LXDE. You can remove MATE by sudo apt-get purge --auto-remove mate-desktop

  • That will only remove the metapackage, not all the software installed by the metapackage. – DK Bose May 17 '17 at 08:36
  • @RecursiveCursive i do not want to this cause it broke my system twice –  May 17 '17 at 08:37
  • @SmitPatil could you describe how it broke your system? I have switched from Kubuntu to cinnamon twice and I have not faced any issues. – RecursiveCursive May 17 '17 at 08:39
  • see this https://askubuntu.com/questions/908223/laptop-boots-like-lubuntu-when-i-installed-lxde-and-lubuntu-desktop-environment also could you please post that how did you switch dektop safely? –  May 17 '17 at 08:41
  • @DKBose how about apt-get remove mate-*. Most of the software should be removed. – RecursiveCursive May 17 '17 at 08:42
  • Such broad commands may have unintended consequences. If you want to go down that road, it's better to first run a simulation. Then, if you understand that all the packages can be removed safely, go ahead! – DK Bose May 17 '17 at 08:47
  • @SmitPatil you can have more than one desktop environment installed. Whenever you want to switch you just have to log out and click on the DE icon near the login.

  • @DKBose agreed! --simulate should help you recognise what is being removed. But I would first suggest that the asker familiarises themselves with Ubuntu and then try out various DEs and removing them. – RecursiveCursive May 17 '17 at 08:51
  • What OP wants to do is to upgrade Ubuntu Mate 14.04 to Lubuntu 16.04. In my opinion, that's not possible. – DK Bose May 17 '17 at 08:54
  • I thought OP wanted to preserve files and move to 16.04 with LXDE, but it looks like he wants a single step upgrade. I don't think that's possible either. – RecursiveCursive May 17 '17 at 11:42
