Try
echo $PATH in a konsole/terminal
Is sbin listet?
When not edit your ~/.bash_profile
Add sbin by PATH=$PATH:$HOME/bin
Looks like after:
PATH=/sbin:$PATH:$HOME/bin
Good luck
I am getting the same message as the OP every time I use Synaptic. Can you clarify the above, i.e. do I add
PATH=$PATH:$HOME/bin and
PATH=/sbin:$PATH:$HOME/binto the ~/.bash_profile?
Leiche meant that you probably have the line
PATH=$PATH:$HOME/binin your
~/.bash_profile, and he suggests that you change it to
PATH=/sbin:$PATH:$HOME/binBut note that this will only change your ordinary user's PATH variable, where
sbin strictly speaking shouldn't be necessary. Run
echo $PATH first, both as your ordinary user and after suing to root both with "su" and with "su -". Post the output.
