running dnf erase powertop
and monitoring signals in packagekit:
dnf erase powertop
gdbus monitor --system --dest org.freedesktop.PackageKit --object-path /org/freedesktop/PackageKit
shows no UpdateChanged signal. It does show up if you use pkcon remove. Note that install is independently broken in #109
This actually works for me using (the recently released) 1.1.0 -- can you try that please? Packages are available for f23 and f24 in koji.
That's great to hear, will this trickle down into F23, or will it only be available in F24? Messing with koji and PackageKit sounds like it will be a bad day.
It'll be updated in f23 on the next stable release, which is by default once every 2 months.
For reference, if anyone is interested, i've committed my work so far to git master: purpleidea/mgmt@3b5678d
More to come!
