IIRC ........ the sudo package has been moved to the 'special' section of the repository, so some effort is needed to find and install it.
It does not therefore show, by default, as available in Synaptic.
The whole point is that the the OP has not had his choice taken away as he originally posted.
"I had always thought Linux was about choice, because of the abuse or stupidity of some, the "choice" has been taken away for all?"
He still has the choice to install and use it if he wishes. He also has the choice to bitch about it, which he did. Just because Linux gives one freedom of choice, does not necessarily mean it will be ease.
I hope his flame retardant shorts kept his behind from getting singed to bad.
Lets look at this from the perspective of someone seeking to install sudo
on their PCLOS machine.
They check Synaptic and it does not show.
They change repository and still it does not show.
It is in effect - for them - not available.
Now if they had the knowledge to enable another section
in the repository of their choice it would no doubt show as available for installation.
So although the choice has not been taken from anyone, it can seem that way, as it has been made difficult to find.
