Bambi Bunny's questions

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

I have Ubuntu 11.10 64-bit and I installed JDK 1.7.0 update 2 x64 via webupd8 page. But currently I have problem with minecraft game. After downloading launcher from Minecraft.net and lauch the game by java -jar /home/zrebec/Downloads/minecraft.jar launcehr is launched normaly, after login the game download the updates but then I got just the black screen with this in terminal:

Please anyone can help me with this? I think that problem will be in architecture becase:

liblwjgl.so: /home/zrebec/.minecraft/bin/natives/liblwjgl.so: wrong ELF class: ELFCLASS32 (Possible cause: architecture word width mismatch)

Any idea please?

I know, maybe this one is off topic because maybe its not Ubuntu problem maybe but in 64-bit works all perfectly and I think that accepted answer can help to many users and can make better playing games under linux. Really. Thank you very much for any idea.

I have 2 monitors and using Oneiric Ocelot Ubuntu. If I have opened firefox on my first monitor and want open new window, new window is always opened on the second monitor. How I can set using 1 monitor in the application? Thanks.

Is there a rational reason to wait for the release date to download, install or update to the next version of Ubuntu?

Should I install ubuntu 11.10 now or is better choice wait to official relase? I know that update should be possible after that but I'm afraid that I will have unnecessary files on my computer from beta version (so, bad windows experiences :) upgrade in windows is always horror). Thank you very much.
