Public bug reported:
Basic commands and some packages commands are failing, I'm unable to
execute shell scripts either, also it is know one other person named
skreet in the ubuntu channel experienced this, he solved it with a
reboot it seems. However for your information I did a recent upgrade of
packages of the last few days including updating to kernel
2.6.24-19-generic. Not sure if this is a critical issue or if it will
reoccur after I reboot.
