Root in File Manager: No longer able to open

[filo]

Should be this one (see also linked upstream site):
https://aur.archlinux.org/packages/rootactions-servicemenu-git
If I remember correctly, this package was kind of replaced by the kde- version because it was not considered “secure”, meaning that it allowed to execute actions protected by design, while the KDE version should be less “open”. You should be able to find some discussions about it also in the forum.
Eg (just a quick search…):

Right click, root options do not work

The AUR package rootactions-servicemenu--which allowed those two illegal options--has been once again supplanted with (AUR) kde-servicemenus-rootactions, which rightfully does not allow those actions. It happened a couple 2-3 days ago, IIRC. Those two actions--both easily accomplished in a different manner--if the user can be bothered to figure them out.
