I power off my laptop with Ubuntu 11.10 during
apt-get upgrade, then I power on and choose Ubuntu in grub, but after the Ubuntu logo, a blurred screen comes.
Then I choose
recovery mode in grub, and then I can type commands as
apt-get upgrade and it tells something wrong with
/var/lib/dpkg/lock, and suggest
dpkg --configure -a, then I tried
dpkg --configure -a but comes something wrong because
read-only file system, then I have no idea..
Any suggest will be helpful.
