error: rpmdbNextIterator: skipping

Top

If we do

dnf -y update

then we get this error message:

You can remove cached packages by executing 'dnf clean packages'.
Error: An rpm exception occurred: package not installed

With

rpm -qa >/dev/null 2> error.log
cat error.log | grep "error: rpmdbNextIterator: skipping h#" | awk -c '{print "rpm -q --nosignature --querybynumber " $5 }' | sort -u | sh

we can check which packages have a problem.

With

rpm -qa >/dev/null 2> error.log
cat error.log | grep "error: rpmdbNextIterator: skipping h#" | awk -c '{print "rpm -e --nosignature --nodeps $(rpm -q --nosignature --querybynumber " $5 ")"}' | sort -u | sh

we remove those package. However you need to make sure that these are not important packages and that you reinstall the updated version via dnf afterwards.

In the case of intel oneapi:

dnf -y install --best --allowerasing intel-aikit
dnf -y install --best --allowerasing intel-basekit
dnf -y install --best --allowerasing intel-dlfdkit
dnf -y install --best --allowerasing intel-hpckit
dnf -y install --best --allowerasing intel-iotkit

And don’t forget to do the update you wanted to do:

dnf -y update --best --allowerasing
