I personally donā€™t use Applmage, but found this on the net. Btw, Ubuntu 18.04 standard support ended in May 2023.

So you are a little bit out of date on yours, if trying apps, you may need to upgrade to a later release.

Im getting ā€˜Failed to download repository informationā€™ when checking for updates. This is recent, or I have just not done this in a very long time. When doing this I also used to get the option to upgrade. Is there an easy way to do this now?

I donā€™t use Ubuntu, but here is a guide to perform the upgrade. Good Luck @pkr1979.

I canā€™t verify the veracity of @easyt50ā€™s link posted above - itā€™s from 2020. I suspect it will not be easy if youā€™re getting ā€œFailed to download repository informationā€ message and will probably entail editing your /etc/apt/sources.list file : ensure you take a backup of this file - probably best to create backup of your whole /etc/apt folder e.g.
sudo cp -rp /etc/apt /etc/apt.bkup.20241218

But I just logged into a Ubuntu 18.04 server - and still get the message (recommending running do-release-upgrade):

121 updates can be applied immediately.
To see these additional updates run: apt list --upgradable

New release '20.04.6 LTS' available.
Run 'do-release-upgrade' to upgrade to it.

But in your case, it will probably want to pull down some 18.04 updates before you can do ā€œdo-release-upgradeā€ - and that appears to be broken - the repository information in your sources.list probably points to a mirror that no longer exists now that Ubuntu 18.04 is EOL (end of life) -

So - theyā€™ve probably moved the location of updates to some other string (/etc/apt/sources.list) :

deb http://au.archive.ubuntu.com/ubuntu/ bionic-updates main restricted

The above points directly, explicitly, at the main Australian mirror for Ubuntu. I believe this still works - but I canā€™t verify 100%ā€¦ Iā€™m pretty sure it would work (no Iā€™m not going to update any production servers :smiley: to test) :

This URL works for me :

and I can see aarnet still host Ubuntu 16.04 ā€˜xenialā€™ update repoā€¦

I have tried doing the updates from the command line with ubuntu in the past and failedā€¦ it will do 18 to 19 but then to go to 20 fails but never says why. Tried also going from 18 to 23 direct without passing through others and also failed, after many many hours.

Better to do a clean new install after copying important data firstā€¦ also better to do new installs of software on new version rather than trying updates for everything

Cannot remember why there was a big change in system around 20 ā€¦

I concurā€¦ Having said that - I had a laptop at work before covid set in - started life on 18.04 then went to 22.04 doing a series of ā€œdo-release-upgradeā€ - it worked okay - but I didnā€™t task it with much - not really powerful enough for games - I mostly just used it to ssh to a customer jumphost, and RDP to customer Windows jumphosts.

But Iā€™d still rather wipe the system and do a fresh install - especially if I had a machine running Ubuntu 18.04 and I wanted 22.04 or 24.04ā€¦

Doing a fresh install will take much less time than all the steps needed to go from 18 to 20 to 22 to 24.

Hi @pkr1979,

Glad the problem is solved. If you get a chance, you might want to mark the post closed (at bottom of your last post ā€“ solution.

Have a good day.
