An error occurred while applying changes

[ZACHSP8]

I get the "An error occurred while applying changes" every time I try to update through updater.

I have had a look online and found info about it but no fix.

Does anyone know how to fix this please as I really don't want to have to do a fresh install as it took me ages to get Kubuntu just how I wanted it?

[Snowhog]

Run the update in a konsole and copy/paste the output.

sudo apt-get update && sudo apt-get dist-upgrade

[ZACHSP8]

I tried them before but just get these errors

You might want to run ‘apt-get -f install’ to correct these.
The following packages have unmet dependencies.
avidemux : Depends: avidemux-plugins (>= 1:2.5.6-dmo6) but it is not installed
E: Unmet dependencies. Try using -f.

[Snowhog]

You're running 14.04. The 404 Not Found means that the specified repository doesn't exist for 14.04. The avidemux 'unmet dependencies' is a separate issue.

It will be helpful to see the contents of each of the files in /etc/apt/sources.list.d.

[ZACHSP8]

do you just need contents of files or file names as well?

there is 27 files in that folder

[Snowhog]

The contents of those files ending in .list.

That is all content of folders ending in .list

It's late here -- 2:19 AM -- so I'm calling it for now. Basically though, you have mixed releases in these repositories; generally not a good idea. Be patient, as you'll likely receive help before I log back on later today.

[ZACHSP8]

Ok thank you

[Snowhog]

Your sources include repositories for:

trusty (14.04)
wheezy (Debian 7 -- obsolete stable release)
vivid (15.04 -- no longer supported; reached End-of-Life on Feb 4, 2016)
raring (13.04 -- no longer supported; reached End-of-Life on Jan 27, 2014)

The files in /etc/apt/sources.list.d/ that contain the entries for wheezy, vivid, and raring 'should' be deleted. Show me what files are there:

ls -la /etc/apt/sources.list.d

And for good measure, show me the content of /etc/apt/sources.list:

cat /etc/apt/sources.list

You need to delete the google-chrome.list and google-chrome.list.save files. Follow the instructions here to add the new repository and signing key.

Delete the c-korn-ppa-trusty.list and c-korn-ppa-trusty.list.save files, as the ppa repository for c-korn is no more.

These are 'root owned' files, so you will have to delete them 'as root'. Either open a console and delete them there:

cd /etc/apt/sources.list.d
sudo rm google-chrome.list*
sudo rm c-korn-ppa-trusty*

or launch Dolphin 'as root' by clicking on the Desktop and then typing:

kdesudo dolphin

Press enter. Type your user password when prompted. Press enter.

Navigate to /etc/apt/sources.list.d and delete the files I've specified. Close dolphin when done.

Once finished, enter a console and type:

sudo apt-get update && sudo apt-get dist-upgrade

[ZACHSP8]

I done everything you said mate and it was all installing well until it just sits at this point on the update.

[Snowhog]

Don't use the graphical package manager; run the commands from a konsole.

You'll need to quite the graphical app and wait a few seconds, then open a konsole and run the commands.

[ZACHSP8]

This is what I get now mate.
