Ah, fun; I guess we need to update the engine that's used, which is still on some very old version;

Engine:
Version: 19.03.14

That version doesn't like cgroups v2;

=== FAIL: e2e/container TestAttachExitCode (0.87s)
attach_test.go:15: assertion failed: Command: docker run -d -i --rm registry:5000/alpine:frozen sh -c read; exit 21
ExitCode: 125
Error: exit status 125
Stdout: aa2bb27139717fd522a124f12c0b56f9d865ed659692b70bc776ab24ff3d3b5c
Stderr: docker: Error response from daemon: cgroups: cgroup mountpoint does not exist: unknown.
Failures:
ExitCode was 125 expected 0
Expected no error

But updating the engine was causing some other tests to fail 😅
