Thanks for sharing the feedback. It's true, Ubuntu MATE Welcome cannot install software when the computer is not connected to the Internet. It also causes problems later when repositories are improperly being added (and attempts to refresh the source list) due to being offline.
To address this, I've added to ability to detect when the computer is offline (specifically, cannot reach the Ubuntu repository server) and displays a message informing the user to connect to the internet. I made some commits in my copy of the repository, to be sent as a pull request later. -- Detect internet connection: https://bitbucket.org/lah7/ubuntu-mate-welcome-16.04/commits/bfa97fab86d99ff7430f1cf65e349d17dd9f4eae -- Display message when offline: https://bitbucket.org/lah7/ubuntu-mate-welcome-16.04/commits/b9f174f4c441cff9b739372cec23b3dcabbba859 If applicable, further work will be needed to refresh the sources list prior to installing the software. ** Changed in: ubuntu-mate-welcome (Ubuntu) Assignee: (unassigned) => Luke Horwell (lah7) ** Changed in: ubuntu-mate-welcome (Ubuntu) Status: New => Incomplete ** Changed in: ubuntu-mate-welcome (Ubuntu) Status: Incomplete => Fix Committed -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1500533 Title: Ubuntu Mate Welcome can't install any software when OS installed without internet connection To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/ubuntu-mate-welcome/+bug/1500533/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
