Ask Ubuntu Asked on January 23, 2021
New install of 20.04.1 running only pi.hole and unifi controller software. It’s Ubuntu desktop, but I’m basically running it headless.
I’ve noticed that I’m getting this set of tracker-miner related errors in syslog about twice a minute. I don’t really care if the tracker runs, although I don’t think I’m actually using it at all. But at a minimum I’d like to decrease the verbosity so I don’t see all of these errors.
I’ve looked around at disabling these services, but haven’t found anything that works yet, including trying to mask them via:
systemctl --user mask tracker-store.service tracker-miner-fs.service tracker-miner-rss.service tracker-extract.service tracker-miner-apps.service tracker-writeback.service
I tried to fix the XDG user directory location by running
xdg-user-dirs-update
Then editing user-dirs.dirs to modify the path names:
XDG_DOWNLOAD_DIR="$HOME/Downloads"
To
XDG_DOWNLOAD_DIR="/home/matt/Downloads"
But that also doesn’t seem to work.
Any thoughts on how to address this on a relatively new and clean Ubuntu desktop install?

I'm in the same situation.
I think the main problem is that /home/pihole dir doesn't exists, and since pihole default shell is "nologin" you can't execute sudo for user and mask the services.
These are the steps I have followed to mask tracker services for pihole user
Create pihole's home directore and give pihole a shell.
sudo mkdir /home/pihole
sudo usermod -s /bin/bash pihole
Go to pihole shell
sudo -i -u pihole
Initialise XDG_RUNTIME_DIR variable in order to run systemctl (systemctl failed to connect to bus - docker ubuntu:16.04 container)
export XDG_RUNTIME_DIR=run/user/$(id -u)
In my case user id is 999 (I think this is pihole default user id)
Mask tracker services for pihole user.
systemctl --user mask tracker-store.service tracker-miner-fs.service tracker-miner-rss.service tracker-extract.service tracker-miner-apps.service tracker-writeback.service
Restore nologin for pihole and delete pihole home dir (optional)
sudo usermod -s /usr/sbin/nologin pihole
sudo rm -rf /home/pihole
Reboot
