Hi everyone i installed KDE and nothing changed so I tried sudo apt-get install plasma-desktop
which told me this
plasma-desktop is already the newest version (4:5.6.5-0ubuntu1~ubuntu16.04~ppa1). The following packages were automatically installed and are no longer required: fonts-roboto fonts-roboto-hinted gdebi-core gnome-icon-theme libcec-platform1v5 libcec3 libfstrcmp0 libhdhomerun2 libjs-iscroll libmicrohttpd10 libnfs8 libtinyxml2.6.2v5 python-imaging python-pil Use 'sudo apt autoremove' to remove them. 0 upgraded, 0 newly installed, 0 to remove and 0 not upgraded.
I did reboot and everything but nothing changed. The theme is still the same.
What am I supposed to do?
