Cannot get past system updates check

[richlion2]

Hello,

I've got Kubuntu on an HP Compaq 8510w with an Nvidia graphics card.
I seem to stuck in a loop in the updates. When Muon starts its says I have new packages to install.
Then it says mys system update is more than a week ago, "please run Check for updates".
When I run I crash in the errors:

Can't locate these packages -
http://ppa.launchpad.net/disper-dev/...amd64/Packages
404 Not Found


http://ppa.launchpad.net/disper-dev/...-i386/Packages
404 Not Found

I attached screenshot.

I read some instructions that I should run :
sudo apt-get dist-upgrade
sudo apt-get update

This still doesn't help and I cannot get passed that error.

Any hints?

Thanks
Richard

Those PPAs no longer exist, hence the errors.
Remove them then run in this exact order:

sudo apt-get update
sudo apt-get upgrade
sudo apt-get dist-upgrade (optional)

richlion2; Hey ...

ninja'd by Vladlenin5000; but my validation:

per:
http://ppa.launchpad.net/disper-dev/ppa/ubuntu/dists/
raring was the last supported release from this PPA.
In Software Center disable this PPA .

now see what results;
terminal commands:

sudo apt-gt update
sudo apt-get upgrade
sudo apt-get dist-upgrade

? finer than a frog's hair

[richlion2]

This command:

sudo apt-get update

shows these errors:

: Nie udało się pobrać http://ppa.launchpad.net/disper-dev/ppa/ubuntu/dists/trusty/main/binary-amd64/Packages  404  Not Found

W: Nie udało się pobrać http://ppa.launchpad.net/disper-dev/ppa/ubuntu/dists/trusty/main/binary-i386/Packages  404  Not Found

E: Nie udało się pobrać niektórych plików indeksu, zostały one zignorowane lub użyto ich starszej wersji.

How should I proceed?

I am interested in why the Muon updater does handle this situation?
I am preparing a laptop for someone who has no clue about an operating system, so I need to make sure I provide support and the updates will not come to a dead end like I had with other distros.

Thanks

If you are going to support a linux distro, then it would be smart of you to make sure :

> That you are using an LTS version (with support for 5 years from release date),
> That your "Sources List" is correct (and stays correct . . only you can change it),
> IF you do not FULLY understand the concepts of official repositories and sources . . please read up on that . . only add PPA's from trusted sources and that exactly match the release version (e.g., 14.04.2 "Trusty")
> Also, recognize each source may be a different physical server also (and url), and could be temporarily "down" at any time . . .often a good idea is to check "choose best server" from time to time in your updater app

So, perhaps an full edit of Sources tab in the updater (or in /etc/sources) will reveal what needs to be removed.

richlion2; Good Morning .


+1 to Geoffrey_Arndt's recommendations.

Looks as there is yet another PPA that might be unsupported ..:

Package management is a system in it's own right, and yes it can get rather deep and complex. This is the reference I still use:
https://www.debian.org/doc/manuals/d..._prerequisites.

How do we proceed - we check the source list file(S) and see what the system is directing to fetch and from where.

To aid you in this determination, post back - Between code tags, please - the outputs of terminal commands:

cat -n /etc/apt/sources.list
tail -v -n +1 /etc/apt/sources.list.d/*

code tag tutorial:
http://ubuntuforums.org/showthread.p...8#post12776168

Get the source(s) list(S) correct for the applications, system then updated and the installed packages upgraded to what is current , Turn the box over to your client .

richlion2; Hello;

Hey, It is all a process of learning and picking up on linux is akin to learning a new language -> patience is a virtue and you only get out of it what you put into it.
In this case the patience thing is finding the cause of the package manager's discontent.
That 2nd PPA that the Package manager is screaming and hollering about:

deb http://ppa.launchpad.net/disper-dev/ppa/ubuntu trusty main

Let's look at what it is trying to fetch:
in your browser:

http://ppa.launchpad.net/disper-dev/ppa/ubuntu/dists/

you see there is no listing for trusty. Thus the system is unable again to comply.

Disable this source also.

Now let's see what the status is:

sudo apt-get update
sudo apt-get upgrade

I do expect there to be new kernels available for install in that output . If so we deal with the "held packages" when the system is stable.

ain't nothing but a thing

[richlion2]

Thank you so much for helping. I did manage to remove those from the repository using Muon (brilliant !!!! )

Update and Upgrade now works.


I may have found the source of my problems.
I search on how to play blue-ray discs with VLC and came up with instructions on this like that may be out of date:
http://askubuntu.com/questions/14008...-ray-using-vlc

The fist two instructions are giving me a warning that the sources are for upcoming releases:

rysiek@richlion9:~$ sudo add-apt-repository ppa:videolan/stable-daily
 This PPA contains daily builds from the latest VLC maintenance branch.

This PPA is used for test building new and upcoming point releases of VLC that can get into Ubuntu through stable release updates (SRU) or security updates. You don't find major version updates in this PPA (e.g. no update from 2.1.x to 2.2.x).

OK

But then I get errors when running sudo apt-get update:

I think I need a more up to date version of how to install stuff for playing blue-ray, maybe someone has hints on where I can find instructions?

I found how to use SMPlayer here:
http://ubuntuhandbook.org/index.php/...blu-ray-discs/

I am not a big fan of SMPlayer, I'd rather use VLC.

Thanks,

richlion2; Yuk;

You are not checking what you are doing:
PPAs are 3rd party software - not supported by ubuntu - use at your own risk, AND do your homework.
http://ppa.launchpad.net/motumedia/m.../ubuntu/dists/
Has no provision for 'trusty' .
So clean up the mess, install VLC properly, and the dependencies required to utilized non-free means.

To see the status of vlc:

dpkg -l vlc

the 1st column in the output we hope is 'ii' .
If it is 'ii" then install the dependencies for non-free use of codecs:

sudo apt-get install ubuntu-restricted-extras
sudo apt-get install libdvdread4
sudo apt-get install libdvdcss libdvdnav4
sudo /usr/share/doc/libdvdread4/install-css.sh
