Same issue here (9.04). Acroread upgrade failed, and a "partial dist- upgrade" failed over and over. I solved it by a "sudo apt-get remove acroread acroread-debian-files;sudo apt-get install acroread".
Not sure if it directly relates, but somewhere between the attempted partial dist-upgrade and the replacement of acroread, "libgl1-mesa-glx" and/or "libgl1-mesa-dri" were replaced by "libgl1-mesa-swx11". This was noticable in the visual effects; for example, window borders became black instead of transparent. I reinstalled "libgl1-mesa-glx" and "libgl1-mesa-dri" using synaptic which seem to have restored the visual effects. -- acroread failed to update in 8.10 https://bugs.launchpad.net/bugs/359518 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
