apache ivy UPGRADE

Affected: >= 2.0.0 and < 2.6.0

Fixed in: 2.6.0

Safe to downgrade to: a release before 2.0.0

1. Check installed version

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

2. UPGRADE to 2.6.0 (Debian / Ubuntu)

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

2. UPGRADE (RHEL / Amazon Linux / Fedora)

sudo dnf upgrade ivy

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 2.0.0 (Debian / Ubuntu)

apt-cache madison ivy sudo apt install ivy=<VERSION_BEFORE_2.0.0> sudo apt-mark hold ivy

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

dnf --showduplicates list ivy sudo dnf downgrade ivy-<VERSION_BEFORE_2.0.0> sudo dnf versionlock add ivy

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.
