Comment 4 for bug 1768050

Hi,
I also have this issue. But have not been able to solve it..
Is a newbie, so please forgive me if I do not provide all info first hand :)
Also I do not know where else to ask for help...

Have done as suggested, but still same issue. just I use nvidia-340.
Using:
Kubuntu 18.04 LTS
Dell E6410
suggested driver Nvidia-340 (default driver do not work with external monitor HDMI any more :( ).

The story. what have I done:
It started with the bug in Ubuntu 18.04 GL dispatch library.
I followed guides om the net and did:
sudo dpkg -P nvidia-340
sudo apt --fix-broken install
sudo apt remove nvidia-340
sudo apt-get clean
sudo apt-get update && sudo apt-get upgrade
sudo apt autoremove

The update Finished OK

Then I tried to install new nvidia-340 as guided in https://askubuntu.com/questions/1077493/unable-to-install-nvidia-drivers-on-ubuntu-18-04
(adding ppa:graphics-drivers/ppa).
Did not work so removed PPA again and sudo dpkg -P nvidia-340

Later the new 340.107 driver was released in official PPA and I tried installing again..
Still the issue. I can not get the nvidia-340 drivers installed..

Get this failure (sorry I am Danish hope you can see the point any way):
Gør klar til at udpakke .../nvidia-340_340.107-0ubuntu0.18.04.1_amd64.deb ...
Tilføjer 'omdirigeret af /usr/lib/x86_64-linux-gnu/libGL.so.1 til /usr/lib/x86_64-linux-gnu/libGL.so.1.distrib gennem nvidia-340'

Der opstod fejl under behandlingen:
 /var/cache/apt/archives/nvidia-340_340.107-0ubuntu0.18.04.1_amd64.deb

So I tried your suggestions.. Not working for Me.

I see there have been some reports recently, but no one seems to take action..

Thanks in advance
