:(
Please be more specific. Why do you think it's a missing dependency?
Because this is impossible to use Telegram in terminal - this is GUI app.
If you want a local x11-base/xorg-server, you should install one; it is not necessary for the server to be local (although that is the most common configuration). That is not an indication that it is a missing dependency; did you have another reason, or should we close as INVALID?
Hm, okay...
