Fixed in: 1.15.15, 1.18.5, 1.19.3, 1.20.1

Safe to downgrade to: a release before 1.4.1

1. Check installed version

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

2. UPGRADE to 1.15.15 (Debian / Ubuntu)

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

2. UPGRADE (RHEL / Amazon Linux / Fedora)

sudo dnf upgrade consul

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 1.4.1 (Debian / Ubuntu)

apt-cache madison consul sudo apt install consul=<VERSION_BEFORE_1.4.1> sudo apt-mark hold consul

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

dnf --showduplicates list consul sudo dnf downgrade consul-<VERSION_BEFORE_1.4.1> sudo dnf versionlock add consul

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.
