techsneeze dmarc report DOWNGRADE

Affected: 1.1

Fixed in: no fixed release known

Safe to downgrade to: a release before 1.1

1. Check installed version

apt-cache policy dmarc-report || rpm -q dmarc-report || dmarc-report --version

2. No fixed release: DOWNGRADE to a release before 1.1 (Debian / Ubuntu)

apt-cache madison dmarc-report sudo apt install dmarc-report=<VERSION_BEFORE_1.1> sudo apt-mark hold dmarc-report

2. No fixed release: DOWNGRADE (RHEL / Amazon Linux / Fedora)

dnf --showduplicates list dmarc-report sudo dnf downgrade dmarc-report-<VERSION_BEFORE_1.1> sudo dnf versionlock add dmarc-report

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.
