It's showing in the launcher the software updater. That means it has new updates.

But i press it and can't open it! The only thing i can do is right click and install updates, or close it and go from the dash and reopen it.

But of course from the terminal it's working perfect.

But why doesn't open from the launcher when it pops up with new updates? and how can i fix it?

Edit:

I tried also to update the manager via the terminal:

Sudo update-manager

But it gets me the error.

Failed to download the repository information. Check your Internet connection.

I don't know if these 2 are linked.

When i had ubuntu 14.04 LTS the steam and dota2 were fine and i was playing with hours.

But since when i upgraded to ubuntu 14.10 the steam doesn't open and neither any steam games.

I reinstall it but nothing again! It doesn't show anything. Just doesn't open.

i can't find how to install and use the labelwriter 450 and it's urgent. i print for my job 50 to 100 labels per week.

i don't know what to do, i just went to ubuntu from windows 8.1.1.

I tried with wine but still doesn't work.
