eucalyptus eucalyptus management console UPGRADE

Affected: >= 4.0.0 and < 4.0.2

Fixed in: 4.0.2

Safe to downgrade to: a release before 4.0.0

1. Check installed version

apt-cache policy eucalyptus-management-console || rpm -q eucalyptus-management-console || eucalyptus-management-console --version

2. UPGRADE to 4.0.2 (Debian / Ubuntu)

sudo apt update && sudo apt install --only-upgrade eucalyptus-management-console

2. UPGRADE (RHEL / Amazon Linux / Fedora)

sudo dnf upgrade eucalyptus-management-console

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 4.0.0 (Debian / Ubuntu)

apt-cache madison eucalyptus-management-console sudo apt install eucalyptus-management-console=<VERSION_BEFORE_4.0.0> sudo apt-mark hold eucalyptus-management-console

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

dnf --showduplicates list eucalyptus-management-console sudo dnf downgrade eucalyptus-management-console-<VERSION_BEFORE_4.0.0> sudo dnf versionlock add eucalyptus-management-console

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.
