Mateusz, if you don't use network manager, please stop it and stop it starting automatically at boot. You can do that with the "rcconf" console application. Also, you should be able to use network/modem manager. Are your issues covered by bug #848164? If not, please open a new bug report.
Adolfo, you are mixing this fixed bug with bug #926763. ** Changed in: software-center (Ubuntu) Status: Triaged => Fix Released -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to software-center in Ubuntu. https://bugs.launchpad.net/bugs/911706 Title: USC relies on NM to be online, can't force online if not using NM Status in “software-center” package in Ubuntu: Fix Released Bug description: Much like Firefox and Evolution, USC relies on knowing the system is online via Network Manager. If NM is 'offline' (e.g. disconnected from wired and not associated with any wifi access points) then USC will not show reviews and will disable the Install button. This is fine if you use Network Manager to get online. If you have to use something else (for example to use pppoe) then you will not be able to install apps in USC, or read reviews. Other applications work around this by providing a 'Go online' option somewhere in a menu. For example Firefox has the 'Work Offline' menu item in the "File" menu which becomes ticked when network manger is offline. Perhaps USC could implement a similar feature?
