View Full Version : [SOLVED] Software updater does not work in Ubuntu 17.04

June 10th, 2017, 08:00 PM
I have a problem similar to that of pepsiman96. Installed Ubuntu 17.04 a short while ago. It seems to be working fine but for the Software Updater app. I have uninstalled and installed it again to no avail, as I always get the same error message:
Failed to download repository information /
check your internet connection /
try again
Nothing wrong with internet connection, of course, but Updater will not update.
No idea of what can be preventing it from functioning.
Help, please.

Have you added any non-standard repositories ? In a terminal, (Ctrl-alt t) what do you get when you type sudo apt-get update ?

Perhaps Skype. Please have a look at what sudo apt-get update shows:

You might try commenting out the Skype line in /etc/apt/sources.list or maybe a file in directlry /etc/apt/sources.list.d.
Next try the ppa s one at a time to fine a problem.

You can add the missing key with
sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys 1F3045A5DF7587C3 then retry
sudo apt-update

Thank you very much. Solution proposed by oldos2er did the trick.

Enjoy your Sunday!
