During a recent upgrade to Ubuntu 9.04, which was recently released, I found that the Tracker search tool index had become corrupted. I tried to tell Tracker to rebuild the index, but experienced some weird issues.
In this quick tip, I’ll show you how to avoid this and other issues by deleting Tracker’s index and cache manually, so that it can start 'from scratch’. Note that if you are having issues with tracker, it is worth trying to rebuild the index from the graphical interface first. This tip is a last resort if you need to clear everything out from scratch and start it again.
According to the documentation, Tracker stores its files in the following locations:
- Configuration Files – ~/.config/tracker/tracker.cfg
- Data Files – ~/.local/share/tracker
- Index Cache – ~/.cache/tracker
If you’re happy with the settings you have, you may want to leave the configuration file intact, and just wipe out the data files and index cache.
Quit Tracker and Delete the Files
First of all, you need to go ahead and quit the Tracker application in the system tray.
Next, you must quit all processes of both trackerd and tracker-indexer, so open up a terminal and run these commands:
$ killall trackerd<br />
$ killall tracker-indexer
And finally, carefully delete the files listed above (excluding the config file, if you don’t think you need to clear that out as well).
So to recap, go ahead and delete the folders:
and if you wish, the config files:
To restart Tracker, I recommend that you log out and log back in so that trackerd and the system tray applet both restart properly. You should then be able to reconfigure it from the beginning as detailed in the original tutorial.
And that should be it – Tracker should rebuild itself from scratch. Useful to know for if things go wrong!
