I have been getting the message below for quite a long time now and have not tried to resolve it ..
$ sudo apt update
E: The repository 'ppa.launchpadcontent.net/upubuntu-com/network/ubuntu jammy Release' does not have a Release file.
N: Updating from such a repository can't be done securely, and is therefore disabled by default.
N: See apt-secure( manpage for repository creation and user configuration details.
So not sure what to do.
If I can get the revised EQMOD from the ppa over the net, what then?
