Timeline

debian advanced package tool UPGRADE
Affected: < 1.2.30 · >= 1.3 and <= 1.4.8
Fixed in: 1.2.30
Safe to downgrade to: a release before 1.3
1. Check installed version
apt-cache policy advanced-package-tool || rpm -q advanced-package-tool || advanced-package-tool --version
2. UPGRADE to 1.2.30 (Debian / Ubuntu)
sudo apt update && sudo apt install --only-upgrade advanced-package-tool
2. UPGRADE (RHEL / Amazon Linux / Fedora)
sudo dnf upgrade advanced-package-tool
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 1.3 (Debian / Ubuntu)
apt-cache madison advanced-package-tool sudo apt install advanced-package-tool=<VERSION_BEFORE_1.3> sudo apt-mark hold advanced-package-tool
3. If no update is available yet, DOWNGRADE (RHEL / Amazon Linux / Fedora)
dnf --showduplicates list advanced-package-tool sudo dnf downgrade advanced-package-tool-<VERSION_BEFORE_1.3> sudo dnf versionlock add advanced-package-tool
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.
