Distros often backport fixes without changing the version number. Confirm with the distro advisory or changelog.

3. If no update is available yet, DOWNGRADE to a release before 15.0.0 (Debian / Ubuntu)

apt-cache madison angular-server-side-configuration sudo apt install angular-server-side-configuration=<VERSION_BEFORE_15.0.0> sudo apt-mark hold angular-server-side-configuration

dnf --showduplicates list angular-server-side-configuration sudo dnf downgrade angular-server-side-configuration-<VERSION_BEFORE_15.0.0> sudo dnf versionlock add angular-server-side-configuration

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.
