microfocus imanager UPGRADE

Affected: >= 3.0 and <= 3.2.5 · 3.2.6

Fixed in: newer than 3.2.5

Safe to downgrade to: a release before 3.0

1. Check installed version

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

2. UPGRADE to newer than 3.2.5 (Debian / Ubuntu)

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

2. UPGRADE (RHEL / Amazon Linux / Fedora)

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 3.0 (Debian / Ubuntu)

apt-cache madison imanager sudo apt install imanager=<VERSION_BEFORE_3.0> sudo apt-mark hold imanager

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

dnf --showduplicates list imanager sudo dnf downgrade imanager-<VERSION_BEFORE_3.0> sudo dnf versionlock add imanager

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.
