Although Discover worked well when I initially installed it, I now get this Error Message (copied to clipboard) every time I launch the app (and this was not fixed by updating Lubuntu and rebooting):
E: The repository ‘https://ppa.launchpadcontent.net/blaze/rtbth-dkms/ubuntu noble Release’ does not have a Release file. W: Updating from such a repository can’t be done securely, and is therefore disabled by default. W: See apt-secure(8) manpage for repository creation and user configuration details.
Any suggestions on how to repair will be welcome. Thanks in advance.
PPAs [or Personal Package Archives] are 3rd party sources, so they only support what the person who created/owns/maintains it chooses to support. From your first paste I can quickly go to
which shows support up to Ubuntu 22.10; with support stopping Feb-2023. It does not provide any support for noble or a 2024-April (24.04) system, so your checks of the PPA to ensure it wasn’t dangerous, still maintained & suitable for your system should have shown that.
You need to remove that source; as it can do nothing more than create a problem with your package updates as it doesn’t provide support for your system, ie. it should not have been added, alas it was, so fix your system by removing it.
I didn’t make any reference to any driver or to anything on Github, only to your [inappropriate] added source and your error message
ie. your addition of https://ppa.launchpadcontent.net/blaze/rtbth-dkms/ubuntu source was what I was saying to remove from your system; as you’re not using a release that PPA supports, thus its addition only hurts you with errors & package problems (until its removed)
You’ll notice the detail is the same, as Lubuntu is still a Ubuntu system, and the screenshot differences between Ubuntu & Lubuntu pages is mostly just different themes used by Ubuntu Desktop (in the Ubuntu pages) or Lubuntu Desktop (Lubuntu manual), operation though the same on each.
In Software Sources (if using your GUI), and go to the Other Software tab, you may only need to uncheck the box on the line related to that source to disable it… How it appears there, or where it will actually be found on your system will be a consequence of how it was added on your system, and I don’t know that.
If it was me; I’d not just a GUI tool, at terminal just cd /etc/apt/sources.list.d/ and find the source file its in, edit/correct or remove the actual text file that contains the entry. I tend to do it this way so I can leave notes in the files as to when & why I make changes; ie. leaving myself notes for the future if required, but we all have our own ways in which we like to do things. To confirm all was good I’d then sudo apt update & scan the output looking for any errors that highlight I made a typo, or made some other mistake… and if output was as expected move to my next chore.
Please disregard my earlier message if you read it before I deleted it. I found the instructions in your link and have now deleted the Blase repository. Hope it works. Thanks.
Thanks for taking the time to respond. Not sure what you mean by my inappropriate source (as I simply cut-and-pasted the error message I received, and I don’t recall mentioning Github, but no matter. As I mentioned shortly after my iniital reply, I found the instructions to Remove the Blaze content (listed in Other Software) and I removed Discover for good measure (relying now on Snap Store for occasional apps I want to find). This also fixed a bluetooth problem I was having, so thanks again for your advice.
