Dear readers,

I have problem upgrading Linux Ubuntu 19.04 to 19.10. Apparently there is a repository that contains erroneous information but I don't know how to remove it. Error message is as follows

"Unable to download updates:
failed to refresh cache: E: The repository 'http://ppa.launchpad.net/mystic-mirage/komodo-edit/ubuntu disco Release' does not have a Release file.

And after some trying new version requires that all the programs are installed. What I should do with this problem? Inserting command

ppa-purge gives error message

E: The repository 'http://ppa.launchpad.net/mystic-mirage/komodo-edit/ubuntu disco Release' does not have a Release file.
Warning: apt-get update failed for some reason

I am using instructions in https://linuxconfig.org/how-to-upgra...10-eoan-ermine and eventually I get following output:

sudo do-release-upgrade
Checking for a new Ubuntu release
No new release found.

Yours

According to this, that PPA repo is obsolete. I would just remove it from your repolist/software sources, then try the update again.

if you have synaptic installed simply click on settings, repositories, other updates, and then scroll till you find that listed. click to high-lite it and then click remove. though if you have one issue chances are you have more. if you don't have too much additional software that you add i'd suggest simply doing a fresh install of 19.10.

Thank you for helping me out with repositories. I removed what had to be removed. The problem that remains is that console doesn't find new version of Ubuntu. All I get is that there is no new version. Do you have ideas concerning this?

More information: I tried command update-manager -d. New version is found but after a while I get

"Please install all available updates for your release before upgrading"

I tried sudo apt-get update without results.

sudo apt-get upgrade informs about nVidia drivers. Apparently there are some programs that aren't installed properly. How can I find out what to finish or do?

did a search and i can't find any piece of software called kimmo, sorry.

Link that you gave didn't solve the problem. Is there any possibility to update from 19.04 to 19.10 using disc?

I think we should start from the beginning.

You're trying to upgrade to the latest version of Ubuntu, correct?

Genrally speaking you have two main options here;

1. Backup any personal data files you have on your current system you wish keep. Then download and then install the latest version of Ubuntu as suggested above - this option might be easier and less painful.

2. Update your current system so you can then upgrade to the latest version of Ubuntu.

If you want to go the option no. 2, then please provide the following info so we have a clear picture of the current status of your system as it stands now;

* Exactly what you have done to date.
* Exactly what error messages or other message you're getting from the package manager for each step you've taken - please use CODE tags to make these messages easier to read.
* Provide the information in this link that you haven't already provided, particularly a listing of enabled software repo's - probably the first dot point in that same link may not be particularly relevant here.

I browsed net for people with similar problems as I do. Yes, I am planning to upgrade from 19.04 to 19.10. Person in this article has got same problems as I do and it might be that few days time of waiting might solve this problem. If nothing changes until Wednesday or Thursday I will give you exact details on what I have done. In any case I thank you for your help with this matter.

Maybe do a full then try again with although you should be doing this through the gui if you are using the desktop version.

actually if you insist on trying to do a full upgrade instrad of a fresh install please use the terminal.

Hello everyone,

I’ll start afresh with the problem. My goal is to update Ubuntu 19.04 to Ubuntu 19.10. I am using instructions in https://linuxconfig.org/how-to-insta...co-dingo-linux This is what I have done so far:

1) PPA repository had errors and I removed causing problem with help of synaptic.
2) I waited few days and today new version became available.

Remaining problem is as follows: I tried sudo ubuntu-drivers autoinstall and the code is as follows:

Apparently nvidia-driver-440 is the reason for problems so how do I remove it? Or should I re-install something? I will give more information if needed.

Kimmo

Can you also provide a listing of enabled software repositories as asked before.

And also the output of the following command;

and we'll go from there.

Hello,

The problem is now solved and Ubuntu is working properly. Sorry for late information. For some reason Nvidia's driver wasn't installed properly and caused problems. I removed it. This page contained useful information on how to solve this issue. Thank you all for patience and help.
