По совету из чата поставил Ubuntu 16.04 LTS
Действительно репозитории работают, получилось поставить и запустить Telegram в виде Snap, сейчас пробую Steam. Ничего себе.
А вдруг и флетпак получится нормальный завести? Эх, сейчас бы видео выживание на Ubuntu 16.04...

There are multiple ways you can search for Telegram channels. One of the methods is really logical and you should all know it by now. We’re talking about using Telegram’s native search option. Make sure to download Telegram from the official website or update it to the latest version, using this link. Once you’ve installed Telegram, you can simply open the app and use the search bar. Tap on the magnifier icon and search for a channel that might interest you (e.g. Marvel comics). Even though this is the easiest method for searching Telegram channels, it isn’t the best one. This method is limited because it shows you only a couple of results per search.
Secret Chats are one of the service’s additional security features; it allows messages to be sent with client-to-client encryption. This setup means that, unlike regular messages, these secret messages can only be accessed from the device’s that initiated and accepted the chat. Additionally, Telegram notes that secret chats leave no trace on the company’s services and offer a self-destruct timer.
