found the reason and the solution on my end: - first i've installed kernel 2.6.33-020633-generic for testing: unfortunatly dkms failed and update-manager removed all nvidia drivers (might say only desactivate), so i uninstalled this kernel and install "nouveau"
- one reboot later, when i've checked for upgrading packages, an initramfs-tools error appear complaining about that missing initrd.img of 2.6.33 kernel. running dpkg --configure -a did not resolve the problem. Have to erase it : rm -f /var/lib/initramfs-tools/2.6.33-020633-generic - run again dpkg --configure -a and that problem is gone. -update & upgrade work fine again. -- Fail to Upgrade to Lucid due initramfs-tools broken package https://bugs.launchpad.net/bugs/520004 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
