Comment 1 Jaroslav Rohel 2021-01-04 07:42:18 UTC
DNF is right. DNF wants to downgrade the "icecat" package back. However,  the "icecat-78.5.0-2.rh2.fc33.x86_64" package is not available in the repositories.

How it can happen?
Packages in the "updates" repository are frequently updated and older packages are removed over time. Probably the "icecat-78.5.0-2.rh2.fc33.x86_64" package was in the "updates" repository some time ago. Your system had been updated to it. Later, updated package "icecat-78.6.0-2.rh1.fc33.x86_64" came to the "updates" repository. The older package "icecat-78.5.0-2.rh2.fc33.x86_64" was removed from the "updates" repository after some time. The "icecat" package was updated on your system again. You want to perform "undo". However, the "icecat-78.5.0-2.rh2.fc33.x86_64" package is not available in the repositories. Therefore, no package matched to the DNF request and DNF generate error message "Error: no package matched".

There's a upstream PR on improving the history command:
https://github.com/rpm-software-management/dnf/pull/1689

It's probably not going to fix the issue completely (the root cause is an unavailable package),
but the new behaviour could be better. There is going to be an option to skip missing packages.
