I can't open gparted. When I open it by terminal: sudo gparted; It gives me this:
Unit tmp.mount does not exist, proceeding anyway.
Segmentation fault (core dumped)
I tried to follow this procedure: Gparted error - Segmentation fault (core dumped)
But it didn't work, I suppose this is a solution ment for old architecture. The result on my terminal is this:
E: Version ‘2.42.0-1’ for ‘libglibmm-2.4-1c2a’ was not found
I remember I used gparted during setup for my system when I installed cosmic. weird. It must be caused by a modification i did. Some sites call it a 'bug'. Some help is required.
Thanks.
As suggested in a comment by @guiverc, it would perhaps be more convenient to use partitionmanager on qt-based systems.
While partitionmanager is initially installed as part of Lubuntu 18.10, an automatic purge removes it and so a full install of Lubuntu 18.10 lacks partitionmanager:
Anyway, the user can simply re-install partitionmanager with
sudo apt install partitionmanager
after which it will appear in the menu as KDE Partition Manager.
