I think I have this solved, but since there are a couple of problems described in this thread I'll state the problem I was seeing:
1) Open mythbuntu-control-centre 2) Click diskless server -> open terminal 3) in terminal (that is now in the changeroot) run "mythbuntu-control-centre" 4) click applications and plugins 5) click something (eg mythcontrols) 6) click apply 7) in confirmation box, click apply The progress box then appears and hangs, with cpu going to 100% on a python process My example isn't the only way to cause the problem, but I wanted to give a specific reproducer. The root cause of the problem was that the forkpty in InstallProgressAdapter::fork() was failing. Thus, no child process came along to update the progress box which was hanging in InstallProgressAdapter::waitChild() waiting for the nonexisting child to exit. The forkpty failed because /dev/pts isn't mounted in the changeroot. My patch updates MythbuntuControlCentre's core.py to mount --bind and unmount /dev/pts in the approprate places in ControlCentre. --Jack ** Attachment added: "patch to mount --bind /dev/pts inside the changeroot" http://launchpadlibrarian.net/30017609/mbc.patch -- cannot install packages using MCC in diskless chroot https://bugs.launchpad.net/bugs/214074 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
