please, I'm using Ubuntu 18.04 LTS and I'm very satisfied yet. But unfortunatelly, Telegram desktop stops work after today's reboot. I really don't know why because it was works correctly before today.

If I'm trying start telegram from command line I have this error message:

~$ telegram-desktop

In fact, I had many probles with snap packages like with gnome-calculator or gnome-system-monitor. This applications was delivered as snap packages after normal install. But I don't think that this applications need to be as snap. After uninstall and install as normal app works correct.

But Telegram I cannot install as normal application via sudo apt install because it is not in stadard ppa repository :( Only I can download AppImage from official Telegram website. But then snap is just a crap of ... (you know) and I recommend migrate to Flatpak.

Please, can you help where can be a problem with snap package of this application?

My Snap applications:

$ ls -la /snap/

vlc works correctly yet :) Thanks for any advice

PS: I tried refresh snap package via snap refresh but it doesn't helps

sudo snap refresh telegram-desktop
snap "telegram-desktop" has no updates available

Thanks for reply

This problem affects me too. The first time I connected required snap interfaces to telegram, and it worked. But today the problem showed up itself again. I fix it by remove and install again telegram with:

sudo snap remove telegram-desktop
sudo snap install telegram-desktop

Note that by now exists a telegram-desktop package within default ppa and you can install it by

sudo apt install telegram-desktop
