SUMMARY In my logs, I get the message kf5.kio.kio_tags: tag fetch failed: "Failed to open the database" repeated quite a number of times. With some context: kdeinit5[16305]: kf5.kio.kio_tags: tag fetch failed: "Failed to open the database" kdeinit5[16305]: kf5.kio.kio_tags: "tags:/" list() invalid url kdeconnectd[4701]: kf5.kio.core: "Kon de map tags:/ niet binnengaan." (translation of the last line: "Could not enter the folder tags:/.") So there may be a connection to kdeconnect. There are no known issues, so therefore marking this as minor. STEPS TO REPRODUCE 1. boot system 2. look at logs OBSERVED RESULT Find the error message, repeatedly. EXPECTED RESULT No error messsage. SOFTWARE/OS VERSIONS KDE Plasma Version: 5.15.5 KDE Frameworks Version: 5.57.0 Qt Version: 5.11.3
What happens if you use the tags:/ URL in Dolphin?
(In reply to Christoph Feck from comment #1) > What happens if you use the tags:/ URL in Dolphin? Nothing, but in the logs, I find (newest first): jun 14 16:00:48 machine kdeinit5[9200]: kf5.kio.kio_tags: "tags:/" stat() invalid url jun 14 16:00:48 machine kdeinit5[9200]: kf5.kio.kio_tags: tag fetch failed: "Failed to open the database" jun 14 16:00:43 machine kdeinit5[9149]: kf5.kio.kio_tags: "tags:/" list() invalid url jun 14 16:00:43 machine kdeinit5[9149]: kf5.kio.kio_tags: tag fetch failed: "Failed to open the database" jun 14 16:00:43 machine kdeinit5[9200]: kf5.kio.kio_tags: "tags:/" stat() invalid url jun 14 16:00:43 machine kdeinit5[9200]: kf5.kio.kio_tags: tag fetch failed: "Failed to open the database"
Can confirm the same error with Plasma 5.16.1, Framework 5.59.0, Qt 5.12.4

Now it works again! Haven't changed anything. Strange
Ok... The reason in my case is that I disabled Baloo and it turned out that the tag function relies on Baloo to work. (Well, it seems that there are actually 2 flavours: the xattr implementation, which relies on Baloo; the Nepomuk custom database implementation, which doesn't need Baloo but was unstable hence deprecated. Correct me if I misunderstood something.)
Please ensure you have the baloo*-file package installed. The packaging schema could differ on your distro, so it's whatever package that has these files: /usr/bin/baloo_file /usr/bin/baloo_file_extractor /usr/bin/balooctl Perhaps we should look into improving the error/log message, make it suggest installing the needed baloo* package(s).

(In reply to Ahmad Samir from comment #7) > Perhaps we should look into improving the error/log message, make it suggest > installing the needed baloo* package(s). Well, I think it should at least mention baloo. Perhaps at the end ‘(Is baloo inactive?)’ or something like that. I suggest closing this bug once the log messages have been improved. (In reply to Christoph Feck from comment #1) > What happens if you use the tags:/ URL in Dolphin? Nothing, even though I added a tag to a file and force-indexed that file.
(In reply to Erik Quaeghebeur from comment #8) > (In reply to Ahmad Samir from comment #7) > > Please ensure you have the baloo*-file package installed. > These are installed. > I don't usually have baloo enabled, so I got the messages mixed up. There are two places where the log messages are coming from: - "Failed to open the database", baloo is properly installed but isn't enabled: https://phabricator.kde.org/D25421 - kio_tags complaining about not being able to open "tags:/" this could be caused by not having baloo-file package installed.
(In reply to Ahmad Samir from comment #9) > - kio_tags complaining about not being able to open "tags:/" this could be > caused by not having baloo-file package installed. I had both that message and the package installed (but disabled). Enabling baloo has eliminated both types of errors.

Enabling > baloo has eliminated both types of errors. I meant kio.core that was complaining (not kio_tags). With a fresh user account: - Baloo is enabled by default - Make sure baloo5-file isn't installed then open dolphin from terminal: kf5.kio.core: "Couldn't enter folder tags:/"
