Comment 1 Aleix Pol 2020-05-15 14:48:16 UTC

Plasma 5.14 had its last release over a year ago. Please update to a supported version.

Comment 2 David C. Bryant 2020-05-15 15:18:46 UTC

Created attachment 128479 [details]
Screenshot of KInfoCenter, so you can see which versions I'm running.

That's a convenient out, Alex. As you can see, my installation is current.

Comment 3 Christoph Feck 2020-05-16 15:23:50 UTC

Plasma 5.14.5 is not current. Kubuntu 20.04 has Plasma 5.18.4, and we already released 5.18.5 and 5.19.0.

Debian doesn't offer updates except for security critical bugs, which you would need to report to the Debian bug tracker. Older Plasma versions are no longer maintained by Plasma developers, so the bug's status is set correctly.
