volosoft abp UPGRADE

Affected: >= 5.1.0 and < 10.0.0 · 10.0.0 rc1

Fixed in: 10.0.0

Safe to downgrade to: a release before 5.1.0

1. Check installed version

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

2. UPGRADE to 10.0.0 (Debian / Ubuntu)

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

2. UPGRADE (RHEL / Amazon Linux / Fedora)

sudo dnf upgrade abp

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 5.1.0 (Debian / Ubuntu)

apt-cache madison abp sudo apt install abp=<VERSION_BEFORE_5.1.0> sudo apt-mark hold abp

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

dnf --showduplicates list abp sudo dnf downgrade abp-<VERSION_BEFORE_5.1.0> sudo dnf versionlock add abp

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.
