Hello, I made a test snap and install it as classic mode. it just run linux command in snap environment

    command: bin/ $1 $2 $3 $4 $5 $6 $7 $8 $9
$1 $2 $3 $4 $5 $6 $7 $8 $9

It is ok when I try pv commands and vg commands But it reports

>   /run/lvm/lvmetad.socket: connect failed: No such file or directory
>   WARNING: Failed to connect to lvmetad. Falling back to internal scanning.
>   /dev/mapper/control: open failed: Operation not permitted

When I try to create lv with command: snap.test “lvcreate -n1 -L1G Test3” and there is no report from snappy-debug

Who can help me?


Is there anyone know?

Is classic mode referring to classic confinement as defined in ?

If running in classic confinement, the results should be the same as when running bin/ explicitly
