[SOLVED] plasma-desktop to be removed

[finotti]

After a while without DUing, I've tried to do it today on my laptop.  I saw that:

Code Select Expand


The following packages will be REMOVED:
  kde-config-touchpad kde-plasma-desktop kde-standard linux-headers-4.14.0-3-amd64 plasma-desktop
  powerdevil


I thought maybe it was a transition, but I don't see that behavior in two machines running aptosid.  I've also checked the "Upgrade Warnings" forum and it seems that there is no transition now.

Running 'apt-get -o Debug::pkgProblemResolver=yes dist-upgrade' I also see some weird things:

If I understand correctly, it is removing plasma-desktop because kactivitymanagerd needs a newer version of it.  But it is available:

Code Select Expand


# apt policy plasma-desktop
plasma-desktop:
  Installed: 4:5.10.5-2
  Candidate: 4:5.12.2-1
  Version table:
     4:5.12.2-1 500
        500 http://httpredir.debian.org/debian unstable/main amd64 Packages
*** 4:5.10.5-2 100
        100 /var/lib/dpkg/status


So, I don't see why apt isn't just installing the newer version.

Any suggestions?  Should I try to DU, let the listed packages be remove and try to install them back again?

[devil]

For one thing, you should update morte often!
Now you could try to

Code Select Expand

apt install kde-plasma-desktop -s and see what that wants to do. Also

Code Select Expand

apt upgrade first and then see what dist-upgade wants to do is a viable road.

Thanks, devil!  For some reason, today, trying DU no package to be removed.  I don't know what fixed, but I am not complaining.

(And indeed I should DU more often, but this laptop stays with my wife, which makes it harder...)

Thanks for the help!!!
