interviewx echo DOWNGRADE

Affected: 2.2 · 2.3

Fixed in: no fixed release known

Safe to downgrade to: a release before 2.2

1. Check installed version

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

2. No fixed release: DOWNGRADE to a release before 2.2 (Debian / Ubuntu)

apt-cache madison echo sudo apt install echo=<VERSION_BEFORE_2.2> sudo apt-mark hold echo

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

dnf --showduplicates list echo sudo dnf downgrade echo-<VERSION_BEFORE_2.2> sudo dnf versionlock add echo

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.
