It seems that when run without root, it reads from the cached results in /etc/blkid.tab, which are only populated if blkid was previously run as root. That could explain why it worked for chrissss, if he had previously run as root.
In other words, this doesn't seem to be fixed; an ordinary user can't run blkid and expect results. -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to e2fsprogs in Ubuntu. https://bugs.launchpad.net/bugs/220275 Title: blkid shouldn't need root privileges Status in e2fsprogs package in Ubuntu: Fix Released Bug description: Binary package hint: e2fsprogs When I execute blkid without root privileges I get an empty result.
