Comment 1 TraceyC 2025-11-05 17:52:14 UTC

Thanks for the bug report.

However, Plasma 5.27.11 no longer receives updates or maintenance from KDE; active versions are 6.4.5 or newer. Please upgrade to an active version as soon as your distribution makes it available to you. Plasma is a fast-moving project, and bugs in one version are often fixed in the next one.

If you need support for Plasma 5.27.11, please contact your distribution, who bears the responsibility of providing help for older releases that are no longer receiving updates from KDE.

If this issue is still reproducible in Plasma 6.4.5 or later, feel free to re-open this bug report.

Thanks for understanding.

Comment 2 kde.stack184 2025-11-05 23:55:45 UTC

Thank you very much for the quick response. I will work to update it and see how it works!

I'm brand new to Linux, I've tried Mint, Ubuntu and not Kubuntu and I really like what you guys are doing I think it is great! I will be sticking with Kubuntu!
