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 7.3 (Debian / Ubuntu)

apt-cache madison wagtail sudo apt install wagtail=<VERSION_BEFORE_7.3> sudo apt-mark hold wagtail

dnf --showduplicates list wagtail sudo dnf downgrade wagtail-<VERSION_BEFORE_7.3> sudo dnf versionlock add wagtail

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.
