I have upgraded 4 systems (two laptops and two desktops, all different hardware) from F23 to F24. Two of them are working fine, and the others seem to be badly messed up in the area of package management. The main symptom I see is that google-chrome-stable was uninstalled during the upgrade, and I can't reinstall it:

[root@cobweb yum.repos.d]# dnf install google-chrome-stable --allowerasing

Error: nothing provides /usr/bin/foomatic-rip needed by redhat-lsb-printing-4.1-32.fc24.x86_64
[root@cobweb yum.repos.d]#

I also get "no matching packages" responses to "dnf list" on packages that are already installed:

root@cobweb yum.repos.d]# dnf clean all

[root@cobweb yum.repos.d]# dnf list cups*

Here, dnf fails to even list packages that "rpm -q" shows are already on the system that should match the pattern.

Anybody seen this or have a clue what I can do other than a full reinstall?

Thanks,
