File system locked on upgrade

[David Angulo]

I have ubuntu version 8.04.3

[code]
root at al:/var/log# cat /etc/lsb-release
DISTRIB_ID=Ubuntu
DISTRIB_RELEASE=8.04
DISTRIB_CODENAME=hardy
DISTRIB_DESCRIPTION="Ubuntu 8.04.3 LTS"
[/code]

I did an upgrade last night using the GUI update manager instead of
apt-get.  I can not find any errors related to the upgrade anywhere in
the /var/log hierarchy (but maybe I do not know what to look for or
maybe I do not know where to look).  Today, my filesystem is read only
after reboot.  I tried rebooting again, but same thing.  My fstab has
not changed for months, and here is the relevant entry:

[code]
# /dev/sda3
UUID=39f06358-2cfe-4c97-81c0-aabb58d1b2d0 /               ext2
defaults,errors=remount-ro 0       1
[/code]

Any ideas on what I should do or where I should look?
