Then I noticed processes running from an automatic upgrade that ran on September first. Whenever I run "dpkg --configure -a", it gets stuck on blkid hanging. When I run the same command manually through strace, it seems to get hung on opening the floppy drive, which does not exist: # strace -o blkid.log blkid -l -t UUID=55e42e8c-9316-46bf- b6a3-888f7368c779 ... lstat("/dev/fd0", {st_mode=S_IFBLK|0660, st_rdev=makedev(0x2, 0), ...}) = 0 access("/dev/fd0", F_OK) = 0 stat("/dev/fd0", {st_mode=S_IFBLK|0660, st_rdev=makedev(0x2, 0), ...}) = 0 openat(AT_FDCWD, "/sys/dev/block/2:0", O_RDONLY|O_CLOEXEC) = 4 openat(4, "dm/uuid", O_RDONLY|O_CLOEXEC) = -1 ENOENT (No such file or directory) close(4) = 0 openat(AT_FDCWD, "/dev/fd0", O_RDONLY|O_CLOEXEC This bug was submitted by running ubuntu-bug on one of the hung instances of blkid. https://ubuntuforums.org/showthread.php?t=2450510 ProblemType: Bug DistroRelease: Ubuntu 20.04 Package: util-linux 2.34-0.1ubuntu9 ProcVersionSignature: Ubuntu 5.4.0-42.46-generic 5.4.44 Uname: Linux 5.4.0-42-generic x86_64 NonfreeKernelModules: zfs zunicode zavl icp zcommon znvpair ApportVersion: 2.20.11-0ubuntu27.8 Architecture: amd64 CasperMD5CheckResult: skip CurrentDesktop: MATE Date: Tue Sep 15 10:18:23 2020 ExecutablePath: /sbin/blkid InstallationDate: Installed on 2016-05-28 (1571 days ago) InstallationMedia: Ubuntu 16.04 LTS "Xenial Xerus" - Release amd64 (20160420.1) SourcePackage: util-linux UpgradeStatus: Upgraded to focal on 2020-08-20 (25 days ago) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/util-linux/+bug/1895686/+subscriptions -- Mailing list: https://launchpad.net/~touch-packages Post to : touch-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~touch-packages More help : https://help.launchpad.net/ListHelp
