Sorry, never done anything with snaps before.
And devnull... I tried to report an issue to them, it was a frustrating experience...
I normally only use Mumble. But everyone always asks for Discord.
Ironically debian is part of the problem, false sense of security. AFAIK the same telemetry applies to you anyway unless debian completely recompiled the client? Hit F12 to watch the console or look at your firewall.
Could it be because you enabled save password? Honestly don't know, didn't do that.
I have not been able to determine any functional limitations so far. But Discord tries the calls every few seconds. And I wonder what they're good for. I haven't found anything useful on the net yet. Not a big problem, I guess. But annoying.
However, I would be interested to know why they banned you. That's a bit of a serious problem if that happens.
Discord has a "feature" where it automatically tells all your Discord friends what game you're playing, with a "Playing World of Warcraft" (or whatever game) below your name on your friend's Discord panel(s).
Discord implements this feature by doing a scan, once every five seconds, of every numeric entry in the /proc file system. Let's say your current Linux user id is "joe", and one (of hundreds) of processes you are running is process pid == 999. Then Discord will first stat "/proc/999", and if that proc directory is owned by yourself, "joe", it will then further try to "open /proc/999/cmdline" and " readlink /proc/999/exe", in an effort to see if you're also running a recognized game executable. If (for example) it sees that you're running a World of Warcraft executable, it will tell your connected friend's Discords to add the "Playing ..." annotation below your name "Joe" on their Discord. The above stat of "/proc/999" call does not generate an error (when run by Discord inside a snap sandbox), but the additional two " open /proc/999/cmd" and "readlink /proc/999/exe" do generate EACCES (Permission denied) errors. If the only entries that Discord found matching the pattern "/proc/NNN", for some decimal number NNN, were not owned by the current Discord user, then I imagine that Discord would quietly decide that you're not running any recognized games and go on about its other business, until the next five second loop.
So ... question for snap experts. Could the Discord snap be packaged with a fake "/proc" file system, that contained exactly one entry, an empty directory "/proc/1", owned by uid 65535 (nobody)? I'd wager that Discord would cease flooding my log files with these error messages.
This suggestion of mine fails. Discord has additional expectations on certain entries under /proc and elsewhere in snap's "core" and "snapd" runtime.
Discord also expects to examine the read the symlink "/proc/self/exe", to see by what name it was invoked.
Such examination of /proc/self/exe is fairly common in Linux, allowing a single binary executable file to behave differently, depending on what name it was called when executed.
I hacked around that /proc/self/exe symlink problem, then hit another problem. Discord expected to read /proc/self/mountinfo in order to "determine nfs usage in generateSystemKey" (quoting its error message.)
I hacked around that.
I then got an error
system_key.go:142: cannot determine seccomp compiler version in generateSystemKey: fork/exec /snap/snapd/current/usr/lib/snapd/snap-seccomp: no such file or directoryI hacked around that.
I then got an error
system_key.go:142: cannot determine seccomp compiler version in generateSystemKey: invalid version-info length: "2c4cf1ac0f802f4eb72a2ae972b18425228c8510 2.4.1 8c73f36d3de1f71977107bf6687514f16787f639058b4db4c67b28dfdb2fd3af bpf-actlog"I then gave up.
Perhaps I will next try running Discord inside a virtual machine, that I can setup just to keep Discord happy (and deprive it of the opportunity to spy on what else I run on my system.)
Took quite a bit of doing because Ubuntu is not really set up for multi-user privacy.
I could say the same about my friends using Windows.
Then they laugh when i can;t get a game to run in wine.
I did manage to convince them to use Teamspeak.
But i do shoulder the cost of 5$/month for a droplet on digital ocean
Teamspeak is popular too, at last It was some years ago I think, but too bad it's proprietary.
I suppose you and your friends use it mainly for vocals, what about other software like Mumble for example?
But the real question is: how did you convinced them?! :D
As for convincing them , there was a small scandal a little while ago where it was revelead that supposedly some Discord staff were furries and were tollerating certain "videos" between humans and non humans being shared through discord.
FBI was apparently involved.
It also helped that the server was made and paid for by me and i maintain it so all they had to do was download the client and connect.
Think we used team speak and skype in the past before discord.
Also some friends did have some bad disconnects with discord.
