this is a serious problem and very easy to reproduce: on an openvz host try to install one of the ubuntu templates from here: http://wiki.openvz.org/Download/template/precreated i tried with ubuntu-9.10-x86.tar.gz and ubuntu-9.04-i386-minimal.tar.gz
when you change the /etc/apt/sources.list to the next distribution and perform an apt-get update && apt-get dist-upgrade the container will hang on next reboot with this error: # vzctl enter 1234 enter into VE 1234 failed Unable to open pty: No such file or directory the dist-upgrade to ubuntu 9.10 was working again after inserting the script from Stéphane Graber, but not anymore with the dist-upgrade to ubuntu 10.04. -- OpenVZ kernel out of date, karmic requires 2.6.27 https://bugs.launchpad.net/bugs/436130 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed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
