PPA Install fails on Ubuntu 18.04,

[LuigiWriter]

From https://github.com/teejee2008/timeshift Used sudo add-apt-repository -y ppa:teejee2008/timeshift got W: An error occurred during the signature verification. The repository is not updated and the previous index files will be used. GPG error: https://deb.opera.com/opera-stable stable InRelease: The following signatures couldn't be verified because the public key is not available: NO_PUBKEY DD3C368A8DE1B7A0 E: Failed to fetch http://ppa.launchpad.net/rolfbensch/sane-release/ubuntu/dists/bionic/InRelease 403 Forbidden [IP: 91.189.95.85 80] E: The repository 'http://ppa.launchpad.net/rolfbensch/sane-release/ubuntu bionic InRelease' is no longer signed. N: Updating from such a repository can't be done securely, and is therefore disabled by default.

Thought instructions on other sites might have been the problem, so came to GitHub. This is the same message I got with instructions from other sites.

Will install from older deb. hope a deb for this version is available soon. If more needed, let me know, will do my best to help. Luigi

Not necessarily a solution to the problem, but a suggestion to bypass the obstacle: Would an update of the Ubuntu LTS you access be an option? Because -- according to the package index -- with the release of focal (20.04 LTS), timeshift became available directly from Ubuntu's repositories. And some time in summer, the point release 22.04.1 for jammy will become available, too.

Thanks, I will be upgrading to focal (20.04 LTS) as soon as I get this estate put to bed [going on 2.5 years]. This happened because I decided I needed to get my wife's computer's OP system backed-up properly and since TimShift has been working just fine for some time on my laptop. I had a moment I could fit in downloading FWbackup and TimeShift, and hook up the terabyte. Well one moment that sort of grew . . .. They tend to do that to me. Gives you some indication of my reluctance to upgrade Ubuntu in the middle of a sometimes time sensitive major task.

Do you think the one version older Deb would be adequate for the meantime, or problematic? A deb tends to remove my dyslictic instruction following from the task. Again thanks for the suggestion.

Is it possible for you to replicate the following?

To start: In a rarely used, small spare partition, there is an elder xubuntu 18.04.4 LTS, (i.e., ubuntu with the xfce4 desktop), an information I retrieved by running lsb_release -a from the terminal. The kernel is older than the one in your report (Linux 4.15.0-96-generic (x86_64)).

From timeshift's release page, I fetch the .deb for the 64bit OS by Nov 16, 2020 which is timeshift_20.11.1_amd64.deb which eventually will be installed by

sudo dpkg -i timeshift_20.11.1_amd64.deb

without an additional ppa.

However, a first attempt to get this running failed because of two unresolved dependencies. Thus, in LTS 18.04

1. install two btrfs related packages from the terminal by

   sudo apt-get install btrfs-prgs btrfs-tools
   

2. then enter the folder with the timeshift .deb downloaded, and issue

   sudo dpkg -i timeshift_20.11.1_amd64.deb
   

   to install timeshift on top.

These two steps provided a new entry in the program pulldown menu and a functional timeshift to backup data of the OS. (For the real user data stored within /home, my preference goes to luckybackup and vorta/borg.)

Sorry for the late reply. I want to give it a try, just need to get a couple of avalanches diverted first. I Hope to be able to give you a result by this weekend. Again thanks for the effort and help.
