3. If no update is available yet, DOWNGRADE to a release before 10.0.0 (Debian / Ubuntu)

apt-cache madison http-client-manager sudo apt install http-client-manager=<VERSION_BEFORE_10.0.0> sudo apt-mark hold http-client-manager

dnf --showduplicates list http-client-manager sudo dnf downgrade http-client-manager-<VERSION_BEFORE_10.0.0> sudo dnf versionlock add http-client-manager

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.
