I'm not aware of what could be done on the Qt side, as it's related to the 14.04.X LTS HWE upgrades where X >= 2. The upgrade is complex and some of the mesa packages have seen slight changes (in addition to being just -lts-vivid suffixed).
It's not as qtbase5-dev could not be installed as such, it's that apt needs to be hinted additionally with eg that libgles2-mesa-dev for the install to succeed. So apt could handle the situation better, or something could maybe improved in the HWE packages. ** Package changed: xorg-lts-vivid (Ubuntu) => mesa-lts-vivid (Ubuntu) ** Also affects: apt (Ubuntu) Importance: Undecided Status: New ** Changed in: qtbase-opensource-src (Ubuntu) Status: Confirmed => Incomplete -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1435324 Title: qtbase5-dev not installable on Ubuntu 14.04 LTS To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/apt/+bug/1435324/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
