System initially presented an "Ubuntu has experienced an internal error" crash report for /usr/libexec/localsearch-extractor-3 (part of tracker-extract), with SIGSEGV in Gfx8BitFont::Gfx8BitFont().
ps aux | grep -i "tracker" showed no running tracker-store or tracker-miner-fs processes. (The localsearch-3 process may attempt to start but crashes or exits due to missing dependencies, as evidenced by the apport report attached below).
Desktop search (via the Activities Overview) is non-functional for files.
Core Problem Identified: Missing systemd User Service Units for Key Components:
While the tracker-extract package does correctly ship its systemd user service unit files (as confirmed by apt-file list tracker-extract | grep systemd outputting localsearch-3.service, localsearch-control-3.service, and localsearch-writeback-3.service), the critical underlying issue is that the tracker-miner-fs and tracker-store components are still missing their necessary service definitions.

systemctl --user status tracker-miner-fs.service consistently reports "Unit tracker-miner-fs.service could not be found."
systemctl --user status tracker-store.service consistently reports "Unit tracker-store.service could not be found."
Crucial Evidence of Missing Files (from apt-file list):
To confirm the reason for the "Unit not found" errors, I used apt-file list to inspect the contents of the installed packages:

apt-file list tracker-miner-fs | grep systemd returns no output. This definitively proves that the tracker-miner-fs package, as shipped in Ubuntu 25.04, does not contain or install its systemd user service unit file (tracker-miner-fs.service).
apt-file list tracker | grep systemd returns no output. This confirms the tracker package similarly does not ship tracker-store.service or any related systemd unit file.

Title:
  tracker is there, then it is not there!! a very complete puzzling
  problme

Status in tinysparql package in Ubuntu:
  Incomplete

Bug description:
  Upon a fresh installation of Ubuntu 25.04 (Plucky), the tracker
  desktop search and indexing system is not functioning correctly.
  Initially, I encountered an "Ubuntu has experienced an internal error"
  crash report for /usr/libexec/localsearch-extractor-3 (tracker-
  extract), with SIGSEGV in Gfx8BitFont::Gfx8BitFont().

  Further investigation revealed that the core tracker processes were
  not running in my user session:

  ps aux | grep -i "tracker" showed no tracker-store, tracker-miner-fs, or tracker-extract (or localsearch-3) processes.
  When attempting to check the systemd --user service status for these components, it consistently reported "Unit could not be found":

  systemctl --user status tracker-miner-fs.service -> "Unit tracker-miner-fs.service could not be found."
  systemctl --user status tracker-store.service -> "Unit tracker-store.service could not be found."
  Detailed inspection of the installed packages confirms the issue:

  dpkg -L tracker-miner-fs | grep .service returns no output, indicating that the tracker-miner-fs package, despite being installed, does not contain or correctly install its systemd user service unit file (tracker-miner-fs.service).
  Similarly, dpkg -L tracker | grep .service did not show tracker-store.service (though tracker-extract did show localsearch-3.service and related localsearch units).
  Current State:

  The localsearch-3.service (the tracker-extract component) is active and running (systemctl --user status localsearch-3.service shows Active: active (running)). However, it reports recurring Could not get file > errors in its logs, likely due to a lack of input from the non-running miner.
  Desktop search (via the Activities Overview) is non-functional for files, as the essential tracker-miner-fs and tracker-store components are not running.
  Troubleshooting Steps Taken:

  Performed sudo apt update && sudo apt upgrade && sudo apt dist-upgrade.
  Cleared tracker cache: tracker reset -s.
  Attempted a full reinstall by purging and then installing:
  sudo apt purge tracker tracker-extract tracker-miner-fs
  sudo apt autoremove
  sudo apt install ubuntu-desktop-minimal (this reinstalled tracker, tracker-extract, tracker-miner-fs).
  Manually confirmed tracker and tracker-miner-fs packages are installed (sudo apt install tracker tracker-miner-fs reports they are the newest version).
  Rebooted after each major step.
