After successfuly initialize telegram-cli and trying to start nctelegram now, lead to the following error message:

bind: Address already in use
Traceback (most recent call last):

I've installed it through the ArchLinux user repository.

Have you ever used telegram before? I think the reason you have this error is because there is no conversation or no messages. You cannot create new discussion in nctelegram, so if you have never used telegram before you won't be able to use nctelegram. If the error doesn't comes from this, then I don't know what is wrong

[weilbith]

Definitely yes. I've already used it and interacting with telegram-cli directly seems works fine.

I have the same issue. Have used both telegram-desktop and telegram-cli successfully

In particular, this happens only with urwid 2.0. Downgrading 2.0 to 1.3 yields "module urwid cannot be found".

I created a pull request which fixes this issue, it is referenced here: #40 Please, test it and let me know if it works for you.

Thanks again @Mikepicker ! closing this now, it seems to work for everyone
