Updating from 10.8.0 - Ubuntu

[DeckardTBechard]

Updated the link and got back:

Code:

E: The repository 'https://ppa.launchpadcontent.net/nilarimogard/webupd8/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.

Deleted PPA manually and re-added with:

Code:

sudo add-apt-repository ppa:nilarimogard/webupd8

sudo apt update

Got the same message back about no release file, looked into the link and did some searching and found this.
So I deleted it outright then one sudo apt update later, so far so good!

I re-did all the steps from post #10 minus the re-creating of the backups.

Lo and behold it worked! Checked the dashboard; 10.8.13! Yipee~!
Thanks so much! I learned a lot and now I can FINALLY stop using the dev version of the Roku client!
