gruen evewa3 UPGRADE

Affected: >= 31 and <= 53

Fixed in: newer than 53

Safe to downgrade to: a release before 31

1. Check installed version

apt-cache policy evewa3 || rpm -q evewa3 || evewa3 --version

sudo apt update && sudo apt install --only-upgrade evewa3

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 31 (Debian / Ubuntu)

apt-cache madison evewa3 sudo apt install evewa3=<VERSION_BEFORE_31> sudo apt-mark hold evewa3

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

dnf --showduplicates list evewa3 sudo dnf downgrade evewa3-<VERSION_BEFORE_31> sudo dnf versionlock add evewa3

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.
