I've tried, out of interest, an install of Ubuntu (which incidentally also carries the mesa files) from recent daily builds and also of the recently released beta.
Ubuntu is not displaying the behaviour that appears with Kubuntu. It is possible to transfer the iso to a usb stick, run it from there in safe graphics mode and do an install to a partition on the PC. As we know at this time this is not possible for Kubuntu. I post this thinking it might be relevant. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1920665 Title: Ubiquity KDE crash on try/install and from live session with "malloc(): unaligned tcache chunk detected" To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/mesa/+bug/1920665/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
