Can't install or update software

[Consideration] Is Manjaro the right distribution for you?

If, for whatever reason you can’t, won’t or don’t want to keep a consistently updated system then Manjaro might not be a good fit for you.

And if you’re not up-to-date you won’t be able to install new software. Or upgrade existing software.

All that said, why did you select “no” for the replacements? Had you stayed up to date and followed the Stable Updates you’d have seen that KDE-related packages were renamed to *5 packages, which needs to be replaced.
