Note

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 5.10.0 (Debian / Ubuntu)

apt-cache madison autonomous-digital-experience-manager sudo apt install autonomous-digital-experience-manager=<VERSION_BEFORE_5.10.0> sudo apt-mark hold autonomous-digital-experience-manager

3. If no update is available yet, DOWNGRADE (RHEL / Amazon Linux / Fedora)

dnf --showduplicates list autonomous-digital-experience-manager sudo dnf downgrade autonomous-digital-experience-manager-<VERSION_BEFORE_5.10.0> sudo dnf versionlock add autonomous-digital-experience-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.
