Ubuntu LTS -- 24.04
Ubuntu Plucky 25.04, not LTS

This further shows that the PPA you added has no packages in it for 25.04.

Also, most of your Ubuntu repos are missing:

Code:

sudo apt update
[sudo] password for adminuser:
Hit:1 [URL]http://security.ubuntu.com/ubuntu[/URL] plucky-security InRelease
Hit:2 [URL]https://dl.winehq.org/wine-builds/ubuntu[/URL] plucky InRelease
All packages are up-to-date.

It should look a bit more like this (More than two 'hits'):

Code:

$ sudo apt update
Hit:1 http://au.archive.ubuntu.com/ubuntu plucky InRelease
Hit:2 http://au.archive.ubuntu.com/ubuntu plucky-updates InRelease
Hit:3 http://au.archive.ubuntu.com/ubuntu plucky-backports InRelease

Get:6 http://au.archive.ubuntu.com/ubuntu plucky/restricted Translation-en_AU [536 B]
Get:7 http://au.archive.ubuntu.com/ubuntu plucky/multiverse Translation-en_AU [45.0 kB]
Hit:8 http://security.ubuntu.com/ubuntu plucky-security InRelease <------------------------------------------THIS is the**only** stock repo  you have. No php for you! Or anything else.

Nothing is blocked, your main software sources have been removed/disabled, plus added an unnecessary PPA that only has packages for a different release than what you are using.

Remove that PPA using ppa-purge, or delete its file from /etc/apt/sources.list.d
Restore the sources disabled/removed, and just install the PHP packages you need.

php8.4-cli is already in 25.04.

You should be able to use the Software Sources tool, unless that is still broken for the purpose.
If you have a damaged sources file or cannot undo or restore it, here is what your /etc/apt/sources.list.d/ubuntu.sources file should contain:

Code:

Yours will have a different country code in the archive.ubuntu.com url than mine, or not have one at all, so substitute 'gb' for 'au' or just use 'archive.ubuntu.com'
Hopefully your file just has things commented out with a '#', which makes it easy to edit using Kate or Kwrite

**jlittle** · 2025-09-23T06:09:50

IMO if it's a borked install, it is usually far quicker wipe and start again.

**claydoh** · 2025-09-23T06:48:30

Yeah, but I am hoping it is just a damaged or modified source file

**Knovice** · 2025-09-24T09:38:52

Thank you claydoh for the replies thus far.

1. Apparently my version of fastfetch - which is not the most recent but cannot currently be updated - does not display the actual version number. The version of Kubuntu is 25.04 - which is the latest.

2. I believe that I created the current problems when I tried to install Hypnotix - by merely pasting commands into the Terminal (in retrospect, a bad idea) - only discover that it is a Linux Mint only app (at least as far as a novice is concerned). Ever since then I have had PPA/repository issues. I cannot install anything via the Terminal and, whenever opened, the Discover software manager always displays repository errors such as:

W: Repositories should provide a clear-signed InRelease file, but none found at https://ppa.launchpadcontent.net/ond...ucky/InRelease.
E: The repository 'https://ppa.launchpadcontent.net/ondrej/php/ubuntu plucky 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.

3. My 'sudo apt update' ouput does not look good:

adminuser@adminuser-80tk:~$ sudo apt update
[sudo] password for adminuser:

adminuser@adminuser-80tk:~$

4. With regard to ppa-purge - I do not think I was given the correct format:

adminuser@adminuser-80tk:~$ ppa-purge
Warning: Required ppa-name argument was not specified
Usage: sudo ppa-purge [options] <ppa

paowner>[/ppaname]

ppa-purge will reset all packages from a PPA to the standard
versions released for your distribution.

Options:
-p [ppaname] PPA name to be disabled (default: ppa)
-o [ppaowner] PPA owner
-s [host] Repository server (default: ppa.launchpadcontent.net)
-d [distribution] Override the default distribution choice.
-y Pass -y --force-yes to apt-get or -y to aptitude
-i Reverse preference of apt-get upon aptitude.
-h Display this help text

Example usage commands:
sudo ppa-purge -o xorg-edgers
will remove https://launchpad.net/~xorg-edgers/+archive/ppa

sudo ppa-purge -o sarvatt -p xorg-testing
will remove https://launchpad.net/~sarvatt/+archive/xorg-testing

sudo ppa-purge [ppa:]ubuntu-x-swat/x-updates
will remove https://launchpad.net/~ubuntu-x-swat/+archive/x-updates

Notice: If ppa-purge fails for some reason and you wish to try again,
(For example: you left synaptic open while attempting to run it) remove
the line "Enabled: no" from the Components section in the PPA ".sources"
file or uncomment the PPA from its ".list" file, run apt-get update and
try again.

adminuser@adminuser-80tk:~$ sudo ppa-purge
[sudo] password for adminuser:

sudo ppa-purge [ppa:]ubuntu-x-swat/x-updates

try again.

adminuser@adminuser-80tk:~$

5. Even if there is a way to get ppa-purge to work, I would not know how to restore the ppa. So please give me the the restore command as well.

**claydoh** · 2025-09-24T13:09:07

Use ppa-purge the same way you used add-apt-repository to get the ppa.
So:

Code:

sudo ppa-purge ppa:ondrej/php

Next, paste the contents of the file /etc/apt/sources.list.d/ubuntu.sources.

You can browse to it in Dolphin and just double-click the file.
We want to compare it to the one I posted, and we can tell you what needs to be edited or added to fix it.

I believe that this will be a fairly easy fix, all done using Kate or Kwrite. No command line, and only needing a password when saving the file.

Yes, investigating what the commands do, and where the software is coming from are all good ideas.

Linux Mint apps can be installed on Ubuntu -- Mint *is* about 97% Ubuntu under the GUI. But any PPA I have seen for them seem to only support Ubuntu LTS -- as Mint is based on that.

Keep it simple for now, install apps from Discover. Linux packaging is confusing, and maybe even messy when straying from the official sources and app stores.

You can always seek opinions if you find something you want but aren't sure about.

Ok, ppa-purge won't work on a PPA that doesn't have any packages, lol, I forgot that.
Sorry!

You will need to just manually delete the file /etc/apt/sources.list.d/ondrej-ubuntu-php-plucky.sources, or whatever file has 'ondrej' in the name.
This will require sudo on the command line, or Admin mode if you have that -- right click somewhere in your Dolphin window and look for 'Open as Administrator' or similar option. Be careful here, and close that window when you have deleted the file.

Next, edit the ubuntu.sources file and remove the line Enabled: no
Save, and try running apt update again.

You *should* be back to normal now.
