pactware pactware UPGRADE

Affected: >= 5.0 and < 5.0.5.31 · 2.4 sp5 · 3.0 sp4 · 3.5 · 3.6 sp1

Fixed in: 5.0.5.31

Safe to downgrade to: a release before 2.4

1. Check installed version

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

2. UPGRADE to 5.0.5.31 (Debian / Ubuntu)

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

2. UPGRADE (RHEL / Amazon Linux / Fedora)

sudo dnf upgrade pactware

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 2.4 (Debian / Ubuntu)

apt-cache madison pactware sudo apt install pactware=<VERSION_BEFORE_2.4> sudo apt-mark hold pactware

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

dnf --showduplicates list pactware sudo dnf downgrade pactware-<VERSION_BEFORE_2.4> sudo dnf versionlock add pactware

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.
