in Ubuntu 14.04, can't update due to strange 'internet connection' problem

[floyd2]

Hi there - I'm totally new, please be extremely patient and tolerant in your replies .
I'm trying to get some software, but keep getting the 'from untrusted sources' message. I get it for everyting - like Chromium - so decided to risk it and just click 'OK'. But if I do that enough, it goes back to square one, so I don't get the new software.
Then, I decided it might be update related, so I went to get my updates, but when I do that, I can't install them. the updater tells me to check my internet connection. I don't understand this, because the internet seems to be working fine - that's why I can post this.
Any suggestions are most welcome.

cheers,

Floyd

Can you show us the output of

sudo apt-get update
sudo apt-get upgrade

in terminal for a start please.

Use code tags for the copied output, please, which is the # icon in the toolbar of the "Reply to Thread" text input box.

[floyd2]

Thanks for that. This is the output of the first command, sudo apt-get update (hope I've got the icons right)

....and a similar heap of stuff has come through from the second command. I'm going to try one of my downloads now and after restarting the thing

[floyd2]

Re-started it, same problem, so here is the output for the second command: sudo apt-get upgrade:

#Reading package lists... Done

The following packages have been kept back:

[floyd2]

well, I'm still here. Just did update and upgrade as before. Can't install the updates that Ubuntu recommends because of the untrusted source problem and can't download things (just tried it with a browser)....any suggestions very gratefully recieved!

[bapoumba]

Your Opera repository is giving a 404 (even for me here). Please remove it from Software Sources, close the Software Sources window and run again :

sudo apt-get update
sudo apt-get upgrade

[floyd2]

thank you. So I should remove Opera and run those two again? Will do! Thanks a lot (please let me know if that's NOT the way to remove it)

cheers,

Floyd

Yes, there is a GPG error, we will see if it remains or not, that will have to be taken care of separately.

[floyd2]

Done! I removed Opera, restarted the computer and tried again. I still got a couple of 404s after the update command, and I still have the 'untrusted packages' problem with downloading software though.

any other suggestions?
thanks again,

Floyd
