Unbuntu Remove ALL PEAK everything -- how?

[rknapp]

Hi,
The presence of PEAK drivers/? on this unbuntu laptop is causing me a TON of problems. (Things work OK on my Windows laptop, but on this machine, I've never been able to get the Peak dongle to work. I can stick with the Windows machine.) How can I please remove all PEAK everything from this machine? The errors below cause failures in other installation scripts which I've ignored for a while, but are now a real problem as I need to install some other stuff.

Please don't say "navigate to where they are and delete them" as I'm too dumb to know where they are, unless you please help me find them or point to exactly where they are. This is Ubuntu Focal, by the way.

Thanks,

~~ Robert

Hello,

It looks like you installed the pcanview package in the past. So, first you have to remove it, if it is still present:

Code: Select all

$ sudo dpkg -P pcanview-ncurses

Then, to get rid of these messages, please type:

Code: Select all

$ sudo rm -f /etc/apt/sources.list.d/peak-system.list

Finally, you can do:

Code: Select all

$ sudo apt update

to check if everything is back to normal...

Best regards,

[rknapp]

Stephane,

Thanks so much for your attention to this problem! YOUR PLAN WORKED PERFECTLY.

Now, when I tried sudo dpkg -P pcanview-ncurses
[sudo] password for rknapp:
dpkg: warning: ignoring request to remove pcanview-ncurses which isn't installed

However, there was no comment re:
sudo rm -f /etc/apt/sources.list.d/peak-system.list

And -- a sudo apt update confirmed that all was well. This laptop is back to health.

So I want to thank you again, very much,

~~ Robert
