I tried to install Nitrux Icons Theme by command line from apt-get but It does show an error for generating cache
here is what I get through the whole process on the terminal screen:
anass@SuperX3:~$ sudo apt-get install nitrux-icon-theme-kde Reading package lists... Done Building dependency tree Reading state information... Done The following NEW packages will be installed: nitrux-icon-theme-kde 0 upgraded, 1 newly installed, 0 to remove and 29 not upgraded. Need to get 0 B/4,609 kB of archives. After this operation, 40.9 MB of additional disk space will be used. Selecting previously unselected package nitrux-icon-theme-kde.

Thanks in advance
