not really a new user, but definitely not a power user.
I recently got a linux compatible art tablet. problem is, I can't access the downloaded drive for it. it's like it's not even there.
and when I click on the software center, (it's just called Ubuntu software now), and while it shows that it;s booting, it's just not... doing anything.
Also, I did the updates install trick in my terminal, did a few other tricks lifted for here and still nothing. and it tells me that the download center is just not here.
it's gone.
Can someone help me fix this? I would rather not have to reinstall my entire OS.
(edit)
Ok, So I managed to instal the blue software shaped like a bag with a white circle with plenty of square dots inside. and I got GIMP.
but now, I can't install my Veikk A15 tablet despite having downloaded the driver that should work on linux.
also, when I downloaded it, it was marked with a red lock at the bottom right. managed to get that off (feel so proud.) but it still won't install.
I got the .deb one, and when I tried to install it vial terminal, I got this. sudo apt install vktablet-1.0.3-2-x86_6.deb
sudo: /usr/bin/sudo must be owned by uid 0 and have the setuid bit set
what does it mean?
