dnf --showduplicates list acrobat sudo dnf downgrade acrobat-<VERSION_BEFORE_10.0> sudo dnf versionlock add acrobat

Downgrade risk

Downgrading can break dependent software and may reopen older bugs. Read the distro advisory first and test on a non-production host.

After downgrade

Restart the service, and keep the package held until a fixed release ships.
