Fixed in: 7.0.8, 7.3.3, 7.4.2

Safe to downgrade to: a release before 7.1

1. Check installed version

apt-cache policy wagtail || rpm -q wagtail || wagtail --version

2. UPGRADE to 7.0.8 (Debian / Ubuntu)

sudo apt update && sudo apt install --only-upgrade wagtail

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 7.1 (Debian / Ubuntu)

apt-cache madison wagtail sudo apt install wagtail=<VERSION_BEFORE_7.1> sudo apt-mark hold wagtail

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

dnf --showduplicates list wagtail sudo dnf downgrade wagtail-<VERSION_BEFORE_7.1> 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.
