Install Updates reports 'computer not connected to Internet'

[Valtam]

From Jerry's answer "how dare you" I take it that he is irritated that he does not know the  answer and so is shooting the messenger who raised the question.  ;D

'How dare you' - refers to the fact that I will jealously defend the good name of those members who offer their time freely. I for one, certainly won't be offering you any type of support in the future.

...but I don't think it merited the aggression of the responses it received.

If you attack the good name of a Forum that has a history of being helpful, you can expect people to respond passionately about your claims of it not being helpful. Perhaps you should reconsider your move to Linux Mint. You may even receive a 100% response rate to any questions you have there. I will enjoy your disappointment of that expectation from here.
