I wanted to do (today) the upgrade of my Debian Sid. During upgrade (with Synaptic) I got crash with remark that I have to finish packages installation properly with :"dpkg --configure -a".
After the restart (as the root) in the text mode, however, I found that the entire system is read-only and completely locked (for root).
The /etc/fstab file contains "defaults,errors=remount-ro" for /dev/sda1, I can not change it in read-only mode. When I discarded "errors" in fstab through CD live, it did not help.
The mesage from dpkg: unable to access dpkg status area: Read-only file system
Any help is appreciated. Miro
