How do I resolve this so I can access the gui and keep my version updated.

Welcome to Ubuntu Discourse

I edited your post to add code tags. Reading large chunks of text or output makes it harder to analyze.

To add code tags, highlight the text and press Ctrl+E on the keyboard.

To the issue at hand…when did this problem start?

Open a terminal and run these commands, separately, and show us the output with code tags:
inxi -r

If inxi is not installed then sudo apt install inxi

Also, while apt-get can still be used, nowadays it is more common to use apt update

sudo apt update

What errors do you get if you run this:
sudo apt full-upgrade

unbuntunewbie02 · May 27, 2025, 10:45am

Hi Rubi1200

My issue is I cannot run sudo apt update as I get the error this happened today i cannot run the software from the GUI either

rubi1200 · May 27, 2025, 10:51am

Try this command please:
grep -r ondrej /etc/apt/sources.list /etc/apt/sources.list.d/

Copy the output here for review.

Good, now we are getting somewhere

You have multiple versions of the PPA in your sources lists.

Do you want to keep this PPA going forward?

unbuntunewbie02 · May 27, 2025, 12:00pm

Sorry Rubi1200 I believe I only used it to upgrade PHP sometime ago.

If there is a default setting that can added thats fine?

rubi1200 · May 27, 2025, 12:04pm

Well, the issue is that you are getting those errors because there are multiple versions of the same thing.

If you need PHP on your system, the best way forward is to clean this up.

Would you like the commands to do that so there is one “clean” source?

unbuntunewbie02 · May 27, 2025, 12:52pm

Yes please Rubi1200, send me over the commands and I will get them run.

rubi1200 · May 27, 2025, 12:56pm

First, let’s make a backup copy of the files (always recommended).
sudo cp -r /etc/apt/sources.list.d /etc/apt/sources.list.d.bak

If no errors, then this to remove old and conflicting files:
sudo rm /etc/apt/sources.list.d/ondrej-ubuntu-php-jammy* /etc/apt/sources.list.d/ondrej-ubuntu-php-noble.sources.save

Add the correct PPA again:
sudo add-apt-repository ppa:ondrej/php

Finally,
sudo apt update

All good now?

unbuntunewbie02 · May 27, 2025, 2:25pm
