Hi Yurror, thanks for your suggestion. I have downloaded 10.04 rc image and boot with it. In Konsole, I have chroot to my main installation of Kubuntu (upgraded from 9.10, into this disastrous 10.04 dev build). My first attempt to update-initramfs faled, because of lacking permission to create /dev/null. So I exited and did $ sudo mount --bind /dev /mnt/dev $ sudo mount --bind /proc /mnt/proc $ sudo mount --bind /sys /mnt/sys (reference: http://ubuntuforums.org/showthread.php?t=1377010) And then re-chrooted and update-initramfs again. This time it succeeded. Update-grub2 succeeded too.
So I exited the console and reboot out of the live session. But my 10.04 installation still hangs with blank screen when rebooting. It does not seem to be a problem with Grub2, but rather with the kernel (2.6.32-xx I guess). Could anyone confirm if it's all the same problem with https://answers.launchpad.net/ubuntu/+question/107521 Thanks. Just murmuring: what kind of release candidate fails to boot even from the beginning? -- Ubuntu 10.04 doesn't boot on kernels 2.6.32-20, 2.6.32-21 https://bugs.launchpad.net/bugs/565938 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
