Control: forwarded -1 https://bugs.launchpad.net/snapd/+bug/1926283
Control: severity -1 important

Bumping the severity back up, because this breaks unrelated software
(#996036), also re-pointing at the current upstream issue.

Bug#934372: snapd: does not work under cgroup v2 at all

[Ryutaroh Matsumoto]

Package: snapd
Version: 2.42.1-1
Followup-For: Bug #934372
Control: block 943981 by -1
Control: severity -1 minor
Control: user pkg-systemd-maintain...@lists.alioth.debian.org
Control: usertag -1 + cgroupv2

Dear Maintainer,

The situation improved in version 2.42.1, now we have
$ snap run hello-world
WARNING: cgroup v2 is not fully supported yet, proceeding with partial 
confinement
Hello World!

I changed the severity and a usertag cgroupv2, see also
https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=943981

Best regards,
Ryutaroh

Bug#934372: snapd: does not work under cgroup v2 at all

[Ryutaroh Matsumoto]

Package: snapd
Version: 2.40-1
Severity: important

Dear Maintainer,

When I boot Linux using the control group V2, by adding 
systemd.unified_cgroup_hierarchy=1
to the kernel command line, no snap package can be used. For example, snap run 
hello-world
just gives

cannot open cgroup hierarchy /sys/fs/cgroup/freezer: No such file or directory

Best regards,
Ryutaroh Matsumoto
