hi ALl:
i install the snapd in ubuntu 2004, but use snap list to show the snap applications get a failure.
the output is:
root@user-PC:~# snap list
panic: permission denied
goroutine 1 [running]:
github.com/snapcore/snapd/snapdtool.ExecInSnapdOrCoreSnap()
/build/snapd-98dSFU/snapd-2.48.3+20.04/_build/src/github.com/snapcore/snapd/snapdtool/tool_linux.go:205 +0x488

/build/snapd-98dSFU/snapd-2.48.3+20.04/_build/src/github.com/snapcore/snapd/cmd/snap/main.go:452 +0x28
the snapd.service is failure too, the output is:
root@user-PC:~# systemctl status snapd.service

Does anyone know how I would go about fixing it?
Thanks all!
