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 14.0 (Debian / Ubuntu)

apt-cache madison idira-privileged-session-manager-for-ssh sudo apt install idira-privileged-session-manager-for-ssh=<VERSION_BEFORE_14.0> sudo apt-mark hold idira-privileged-session-manager-for-ssh

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

dnf --showduplicates list idira-privileged-session-manager-for-ssh sudo dnf downgrade idira-privileged-session-manager-for-ssh-<VERSION_BEFORE_14.0> sudo dnf versionlock add idira-privileged-session-manager-for-ssh

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.
