progress sharefile storage zones controller UPGRADE

Affected: >= 5.0.0 and < 5.12.4

Fixed in: 5.12.4

Safe to downgrade to: a release before 5.0.0

1. Check installed version

apt-cache policy sharefile-storage-zones-controller || rpm -q sharefile-storage-zones-controller || sharefile-storage-zones-controller --version

2. UPGRADE to 5.12.4 (Debian / Ubuntu)

sudo apt update && sudo apt install --only-upgrade sharefile-storage-zones-controller

2. UPGRADE (RHEL / Amazon Linux / Fedora)

sudo dnf upgrade sharefile-storage-zones-controller

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 5.0.0 (Debian / Ubuntu)

apt-cache madison sharefile-storage-zones-controller sudo apt install sharefile-storage-zones-controller=<VERSION_BEFORE_5.0.0> sudo apt-mark hold sharefile-storage-zones-controller

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

dnf --showduplicates list sharefile-storage-zones-controller sudo dnf downgrade sharefile-storage-zones-controller-<VERSION_BEFORE_5.0.0> sudo dnf versionlock add sharefile-storage-zones-controller

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.
