I have Mint 18 Mate. The following errors appear after typing in
sudo apt-get install k3b" followed with password.

I have retried after reboot but no help. Please let me know what did I do wrongly.

Hi ykffc.

I think that we should go back to first principles on this one, and that is to have a look at your software sources.

So, could you please paste the output from:

Just a note that personally I try to avoid installing most KDE software on non-KDE systems due to the often large number of dependencies required, as you no doubt noticed with k3b. Unless you have a specific reason for using k3b, a burner such as Brasero could well do the job for you.

Troubleshoot your network connection before trying to use apt as your output shows errors only when trying to get out onto the network.

The URLs generating the 404s don't actually exist (click on the "Failed to fetch" entries).

No specific reasons. That is because someone recommended it when reading the following threads.

https://forums.linuxmint.com/viewtopic.php?t=56122

Perhaps I should try again installing it via the software manager. And then try Brasero if there is still no luck.

I still think that we should have a look over your package situation first. The fact that you have 510 packages marked as "to upgrade" shows that either you haven't been keeping on top of updating your system and/or you have some sort of problem with your software sources. The longer you leave that situation without resolving it, the more likely that complications will arise.

So, if you are able to run the command I suggested in post #2 and paste the output here then that would be a good start.
