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 3.2.7 (Debian / Ubuntu)

apt-cache madison octopus-server sudo apt install octopus-server=<VERSION_BEFORE_3.2.7> sudo apt-mark hold octopus-server

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

dnf --showduplicates list octopus-server sudo dnf downgrade octopus-server-<VERSION_BEFORE_3.2.7> sudo dnf versionlock add octopus-server

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.
