Description of problem: mlocate-updatedb.service fails to update database with all files on system. Version-Release number of selected component (if applicable): mlocate-0.26-25.fc32.x86_64 How reproducible: Always Steps to Reproduce: $ sudo systemctl start mlocate-updatedb.service $ locate sos-3.9-py3.8.egg-info $ sudo updatedb $ locate sos-3.9-py3.8.egg-info /usr/lib/python3.8/site-packages/sos-3.9-py3.8.egg-info $ Work-around is /etc/systemd/system/mlocate-updatedb.service: [Service] ExecStart=/usr/bin/updatedb Additional info: $ mount|grep btrfs /dev/nvme0n1p2 on / type btrfs (rw,noatime,seclabel,ssd,space_cache,subvolid=258,subvol=/root) /dev/nvme0n1p2 on /home type btrfs (rw,noatime,seclabel,ssd,space_cache,subvolid=259,subvol=/home) /dev/nvme0n1p2 on /var/log type btrfs (rw,noatime,seclabel,ssd,space_cache,subvolid=256,subvol=/var_log) $ mlocate-updatedb.service runs this script (which has odd permissions): $ sudo cat /usr/libexec/mlocate-run-updatedb #!/usr/bin/sh nodevs=$(< /proc/filesystems awk '$1 == "nodev" && $2 != "rootfs" && $2 != "zfs" { print $2 }') /usr/bin/updatedb -f "$nodevs" $ $ cat /etc/updatedb.conf PRUNE_BIND_MOUNTS = "yes" PRUNEFS = "9p afs anon_inodefs auto autofs bdev binfmt_misc cgroup cifs coda configfs cpuset debugfs devpts ecryptfs exofs fuse fuse.sshfs fusectl gfs gfs2 gpfs hugetlbfs inotifyfs iso9660 jffs2 lustre mqueue ncpfs nfs nfs4 nfsd pipefs proc ramfs rootfs rpc_pipefs securityfs selinuxfs sfs sockfs sysfs tmpfs ubifs udf usbfs ceph fuse.ceph" PRUNENAMES = ".git .hg .svn .bzr .arch-ids {arch} CVS" PRUNEPATHS = "/afs /media /mnt /net /sfs /tmp /udev /var/cache/ccache /var/lib/yum/yumdb /var/lib/dnf/yumdb /var/spool/cups /var/spool/squid /var/tmp /var/lib/ceph /BACKUP /home/BACKUP" $ It looks like /usr/libexec/mlocate-run-updatedb is redundant, given /etc/updatedb.conf.
This message is a reminder that Fedora 32 is nearing its end of life. Fedora will stop maintaining and issuing updates for Fedora 32 on 2021-05-25. It is Fedora's policy to close all bug reports from releases that are no longer maintained. At that time this bug will be closed as EOL if it remains open with a Fedora 'version' of '32'. Package Maintainer: If you wish for this bug to remain open because you plan to fix it in a currently maintained version, simply change the 'version' to a later Fedora version. Thank you for reporting this issue and we are sorry that we were not able to fix it before Fedora 32 is end of life. If you would still like to see this bug fixed and are able to reproduce it against a later version of Fedora, you are encouraged change the 'version' to a later Fedora version prior this bug is closed as described in the policy above. Although we aim to fix as many bugs as possible during every release's lifetime, sometimes those efforts are overtaken by events. Often a more recent Fedora release includes newer upstream software that fixes bugs or makes them obsolete.
This is probably a duplicate of Bug 1498460, and the workaround given there works. The issue is the ProtectSystem=true directive in mlocate-updatedb.service. This causes systemd to run updatedb in a new mount namespace in which the /usr directory (among others) is a read-only bind mount. These directories then get pruned because PRUNE_BIND_MOUNTS is set to "yes" in /etc/updatedb.conf. It is possible that this will be fixed by the improved handling of bind mounts described in Bug 723279#c40, but I haven't tested it.
Fedora 32 changed to end-of-life (EOL) status on 2021-05-25. Fedora 32 is no longer maintained, which means that it will not receive any further security or bug fix updates. As a result we are closing this bug. If you can reproduce this bug against a currently maintained version of Fedora please feel free to reopen this bug against that version. If you are unable to reopen this bug, please file a new report against the current release. If you experience problems, please add a comment to this bug. Thank you for reporting this bug and we are sorry it could not be fixed.
