Hi Alice, it seems that LyX is a very large package download (about 289.0 MB), so I wonder if you may have encountered network issues when installing it? I have been able to install it without issue in Ubuntu 12.04 with Software Center version 5.3.2.
Please let us know if you are still having this difficulty. And thank you for your help! ** Changed in: software-center (Ubuntu) Status: New => Incomplete -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/985979 Title: Crashed whilst trying to install LyX and Adobe Flash To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/software-center/+bug/985979/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
