ibm 4769 developers toolkit UPGRADE

Affected: >= 7.0.0 and < 7.5.62

Fixed in: 7.5.62

Safe to downgrade to: a release before 7.0.0

1. Check installed version

apt-cache policy 4769-developers-toolkit || rpm -q 4769-developers-toolkit || 4769-developers-toolkit --version

2. UPGRADE to 7.5.62 (Debian / Ubuntu)

sudo apt update && sudo apt install --only-upgrade 4769-developers-toolkit

2. UPGRADE (RHEL / Amazon Linux / Fedora)

sudo dnf upgrade 4769-developers-toolkit

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 7.0.0 (Debian / Ubuntu)

apt-cache madison 4769-developers-toolkit sudo apt install 4769-developers-toolkit=<VERSION_BEFORE_7.0.0> sudo apt-mark hold 4769-developers-toolkit

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

dnf --showduplicates list 4769-developers-toolkit sudo dnf downgrade 4769-developers-toolkit-<VERSION_BEFORE_7.0.0> sudo dnf versionlock add 4769-developers-toolkit

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.
