Question

This question has been marked as a duplicate but there is no link to original quetion:

• Setting proxy from terminal

Why is this so? And what can be done for such questions?

Answer 1

The link was probably mistakingly removed after an edit to the question. You can find the duplicate in the question's revisions.

I've re-added the duplicate manually to the question for future vsitors.

Answer 2

You still have the Linked on the right-hand panel. This specific question is probably duplicate of 'apt-get' does not work with Proxy.
