Can't update securely and is therefore disabled?

Question

I have been all over this thread and nothing I've read or tried fixes this for me. I had wine installed but I removed it because I didn't want to mess with it. It appears that has compromised things for me. When I do sudo apt update I receive:

Err:1 http://your.repo.domain/repository disco InRelease

I used to be well versed in Linux but that was like 10 years ago and now I have no idea what I'm doing. Can someone please explain to me how to fix this like I was 5? I changed my server to main server.

I removed wine from the Other Software and it said to reload software so I did and it failed saying: E:The repository 'http://us.archive.ubuntu.com/ubuntu artful-updates Release' does not have a Release file. When searching sources, I see this. I'm running a backup now, as suggested in another thread, can someone help me on where to go from here? Thank you so much!!

artful refers to 17.10 which has been EOL for a long time. When a release goes EOL it's repos are moved from archives0 to old-releases, but you shouldn't have that repo on 19.04 so your sources.list are badly changed. — guiverc, May 09 '19 at 02:05
I suggest that you [edit] your post and add the contents of /etc/apt/sources.list. As @guiverc commented, there are apparently some highly questionable entries therein. — Organic Marble, May 09 '19 at 02:35
@guiverc Oh no! I will update my post now. I never had Ubuntu 17 so I'm not sure how that would get on there? I appreciate your help! — Leslie Lemon, May 09 '19 at 04:16
Please do gedit /etc/apt/sources.list and copy all content to your post, as you're only copying portion of the content now. — Liso, May 09 '19 at 04:20
seems like a partial list. You should be able to type cat [filename] and get the whole thing. — Organic Marble, May 09 '19 at 04:22
@OrganicMarble Updated with the sources document, that appeared to have more information. Can you EITMLI5 what cat [filename] means? — Leslie Lemon, May 09 '19 at 04:23

`E: The repository no longer has a Release file`

Seems you have artful (Ubuntu 17.10) repository on your /etc/apt/sources.list file, as it has reached EOL (End Of Life)— the repository therefore is no longer available.

To fix this, you need to delete or comment the repository, either way will do the jobs.

Open /etc/apt/sources.list using superuser privilege.

sudo gedit /etc/apt/sources.list

Find for this line.

deb http://us.archive.ubuntu.com/ubuntu/ artful-updates main

Comment/delete it, if you comment it the line would look like this.

# deb http://us.archive.ubuntu.com/ubuntu/ artful-updates main

Adding # hashtag sign to beginning of the line, this will deactivate the artful repository.

`Could not resolve 'your.repo.domain'`

Apparently OP has some unknown source on the package source list, apt doesn't recognized it hence the error above.

Same as before procedure, unrecognized source needs to be removed.

sudo rm /etc/apt/sources.list.d/your-repo-name.list

Where your-repo-name.list is the problematic standalone source list.

Try sudo apt update again, it shouldn't produce any error now.

When I try to do this I get ** (org.gnome.gedit:24487): WARNING **: 22:27:33.756: Set document metadata failed: Setting attribute metadata::gedit-encoding not supported You were right though, the # was on everything else in that section except that one. – Leslie Lemon May 09 '19 at 04:28
@LeslieLemon Try this then sudo sed -i '60s/.*/# &/' /etc/apt/sources.list followed by sudo apt update. This will add # character on specified line (60), where line 60 is your artful repo. – Liso May 09 '19 at 04:34
Thank you! I updated my post to include the results from that, from what I can tell it's fixed? – Leslie Lemon May 09 '19 at 04:39
Where does your.repo.domain came from ? I forgot about that apparently – Liso May 09 '19 at 04:40
Uhh that is an excellent question I don't know the answer to... how can I find that out? When checking for software updates I'm being told failed to download repo info – Leslie Lemon May 09 '19 at 04:41
Yup, you lost me. I'm sorry, Linux has changed a lot since I last used it! That or I'm just getting old. – Leslie Lemon May 09 '19 at 04:47
Have you find the file ? – Liso May 09 '19 at 04:49
No I haven't even the slightest clue what to look for, haha. What is the file I'm looking for? – Leslie Lemon May 09 '19 at 04:52
Run this command on terminal sudo find /etc/apt -name '*.list' -exec grep -i 'your.repo.domain' {} \; -print. – Liso May 09 '19 at 04:53
deb http://your.repo.domain/repository/ disco universe /etc/apt/sources.list.d/your-repo-name.list I'm so sorry I misunderstood! – Leslie Lemon May 09 '19 at 04:54
Ok it seems we found the culprit of the error, run this sudo rm /etc/apt/sources.list.d/your-repo-name.list followed by sudo apt update – Liso May 09 '19 at 04:55
Hooray! That says all packages are up to date and no errors. I was also able to check for updates without errors! Thank you so much!! – Leslie Lemon May 09 '19 at 04:57
