power failure during upgrade: root filesystem check failed

[sowdust]

Hello,

I was uprgading my 10.04 to 11.04 on my laptop; I was sure this was plugged in, while it actually wasn't: of course the power ran out during the upgrade process and therefore interrupted it. Now whenever I try to boot the system an error tells me that "Root filesystem check failed" and all I can do is use the shell (not the dpkg process that fails because of the apparently read-only nature of the filesystem).
I tried to look into my /home folder and everything seems to be still there, which is what I cared the most about; now I was wondering if there is a better and safer way to continue the upgrade than formatting the non-home partitions and re-install the operating system from zero, losing all the previously installed applications and their configurations.

Thanks in advance for any suggestion

thank you very much for the suggestion!
this method worked fine:

# dpkg --configure -a
# mount -o remount,ro /
# sync
# reboot
