See Err:6 above. I tried to do a ppa-purge:

sudo ppa-purge ppa:shutter/ppa

Warning:  apt-get update failed for some reason

Apparently I'm doing something wrong, but I don't know what it is. Any suggestions are appreciated.

The target of your ppa-purge command is invalid.

The problematic PPA is ppa:shutter/ppa.

To remove it, use:

sudo ppa-purge ppa:shutter/ppa

Assuming there are no other issues, you can update your system:

sudo apt update
sudo apt upgrade

  • I edited the body of the post to show what happens with the suggested ppa-purge. I'm still looking for help with this as it is still not working. – daveh May 15 '23 at 05:20
  • There are a number of other ways to remove PPAs or sources. Try [this answer](https://askubuntu.com/a/173199) or [remove them](https://askubuntu.com/a/173209) from your sources list by manually deleting or commenting the lines. If none of these help, can you tell us how you added this PPA to begin with? – Nmath May 15 '23 at 06:25
  • I was able to remove the ppa via ``` sudo apt-add-repository --remove ppa:shutter/ppa ``` at that point I could then update and upgrade my system. Thank you Nmath – daveh May 16 '23 at 05:17
