If you run `dmsetup ls` as non-root on amd64, you get an error that's close:
% dmsetup ls /dev/mapper/control: open failed: Permission denied Failure to communicate with kernel device-mapper driver. Incompatible libdevmapper 1.02.136 (2016-11-05) and kernel driver (unknown version). Command failed where as the failure in the log file says: [K/dev/mapper/control: mknod failed: Operation not permitted Failure to communicate with kernel device-mapper driver. Check that device-mapper is available in the kernel. If you run the same command as root on amd64, it works. So my question is: despite having needs-root, is it somehow possible that autopkgtest is running the armhf command as non-root, and the slightly different error message is indicating that, or is it really not available when run as root on armhf. If you have an armhf device with an up-to-date Zesty, can you please check? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1655735 Title: Incompatible libdevmapper 1.02.136 (2016-11-05) and kernel driver (unknown version).
