ezged ezged3 UPGRADE

Affected: >= 3.5.0 and < 3.5.72.27183

Fixed in: 3.5.72.27183

Safe to downgrade to: a release before 3.5.0

1. Check installed version

apt-cache policy ezged3 || rpm -q ezged3 || ezged3 --version

2. UPGRADE to 3.5.72.27183 (Debian / Ubuntu)

sudo apt update && sudo apt install --only-upgrade ezged3

2. UPGRADE (RHEL / Amazon Linux / Fedora)

sudo dnf upgrade ezged3

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 3.5.0 (Debian / Ubuntu)

apt-cache madison ezged3 sudo apt install ezged3=<VERSION_BEFORE_3.5.0> sudo apt-mark hold ezged3

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

dnf --showduplicates list ezged3 sudo dnf downgrade ezged3-<VERSION_BEFORE_3.5.0> sudo dnf versionlock add ezged3

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.
