tracker-miner-fs crashes on Ubuntu 20.04

  • 772

I upgraded to Ubuntu 20.04 today, and after this upgrade tracker-miner-fs seems to crash and restart contiguously; pegging my CPU at 100% until I manually kill the process.

The error I'm getting in /var/log/syslog is:

There's isntructions to permanently stop this process, but I would rather to see it work.

    Removing the tracker database seems to have done the trick:

    rm -r ~/.cache/tracker

  2. This solution worked for me...

    So how to completely disable Tracker, so it no longer indexes any files, and stop having any Tracker process running in the background? You can mask the Tracker systemd services to completely disable it for your current user using this command:

    $ systemctl --user mask tracker-store.service tracker-miner-fs.service tracker-miner-rss.service tracker-extract.service tracker-miner-apps.service tracker-writeback.service

    After this, reset Tracker:

    $ tracker reset --hard

    And reboot.

  3. tracker-miner is having problems with files in your /home/evert/Music/unsorted/iTunes Music folder. Did your system need an fsck?

    Tracker's metadata miners can crash on certain file contents. If you find you have a core stuck at 100%, take a look in /tmp/tracker-extract-files.1000 and you'll likely find a symlink to a problem file. Stop the tracker daemon, move the file (or exclude the directory) and restart the process. It should settle down after a while, as long as the miner never sees that problem file again.

    More possibly appropriate details in my answer: no progress updates from gnome tracker - Ask Ubuntu

  4. For me the key was that tracker was running for system accounts with no home directory (pihole in my case). Once I created a home dir for pihole, problem was resolved (fingers crossed). I looked up the process id from syslog in 'ps -ef' to see which user tracker was running for
