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 3.6.0.0 (Debian / Ubuntu)

apt-cache madison elastic-cloud-storage sudo apt install elastic-cloud-storage=<VERSION_BEFORE_3.6.0.0> sudo apt-mark hold elastic-cloud-storage

dnf --showduplicates list elastic-cloud-storage sudo dnf downgrade elastic-cloud-storage-<VERSION_BEFORE_3.6.0.0> sudo dnf versionlock add elastic-cloud-storage

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.
