It's happening to me now on a RPI3 with Ubuntu 16.04 armhf. Yesterday evening I've deleted two old ext3 partitions to make room for a small BTRFS RAID1 2x 20 Gb partitions and now I was looking for the PARTUUID to write it in cmdline.txt. So blkid had plenty of time to reflect the new layout.
ii util-linux 2.27.1-6ubuntu3.6 armhf miscellaneous system utilities I've tried also with partprobe, to no avail. ii libparted2:armhf 3.2-15 armhf disk partition manipulator - shared library ii parted 3.2-15 armhf disk partition manipulator Both fdisk and parted print the correct layout. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/137314 Title: blkid shows outdated / wrong UUID To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/e2fsprogs/+bug/137314/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
