[ALUG] kubuntu apt-get not installed

Did as suggested 'echo $PATH' gave /lib/init:/sbin:/bin and 'ls' just returns me to desktop cursor and '/usr/bin/apt-get' gives me a fast scroll which I was not able to record and 'cd /bin' gives 'root@elc-desktop:/bin#_' and 'cd/usr/sbin' gives 'root@elc-desktop:/usr/sbin#' Wayne Stallwood wrote

Given that it worked for a while after the upgrade I am guessin that either your system volumes is not available or your path is wrong.

What is the output of - echo $PATH

(case sensitive)

does /bin/ls work rather than ls on it's own ? or /usr/bin/apt-get ?

Can you 'cd' to /bin or /usr/sbin ?
