Links don't work on snap

[Kris]

When I try to open link from snap application this is the error I get:
user-open error: cannot find snap for connection: cannot find a snap for pid <PID>

Same error I get when I use snap `run --shell spotify` and then execute:
`xdg-open https://example.com`

What system are you trying this on?

What does "snap version" returns?

[Kris (kaidorn)]

snap 2.41-1.fc31
snapd 2.41-1.fc31
series 16
fedora 31
kernel 5.3.12-300.fc31.x86_64

[Kris (kaidorn)]

Just updated version of snap:
snap 2.42.2-1.fc31
snapd 2.42.2-1.fc31
series 16
fedora 31
kernel 5.3.12-300.fc31.x86_64

But results are still the same.

is there a particular reason you are using --shell ?

this is a debug option for developers to inspect the environment, IIRC it does not process all app wrappers as you would get them when running without --shell ...

do you see the same behaviour when executing without the --shell argument ?

The reason is incomplete cgroupv2 support, recall that Fedora 31 boots with unified hierarchy by default. Specifically, we're missing snap process tracking abilities here.

Actually, we even have a PR that changes the way we track snap processes https://github.com/snapcore/snapd/pull/7825 We hope to land it around 2.44 timeframe.
