I am using plasma-discover and discover is opening. I am trying to install gimp or inkscape and it asks me password. When I put it correctly it shows task(100%) and stops popping up “cannot obtain lock”.
‘uname -a’ command returns Linux lubuntu 5.4.0-47-generic #51-Ubuntu SMP Fri Sep 4 19:50:52 UTC 2020 x86_64 x86_64 x86_64 GNU/Linux
The image I installed is downloaded from https://cdimage.ubuntu.com/lubuntu/releases/20.04.1/release/lubuntu-20.04.1-desktop-amd64.iso
Please help me out.
