larry wall perl DOWNGRADE

Affected: 5.6 · 5.6.1 · 5.8.0 · 5.8.1 · 5.8.3

Fixed in: no fixed release known

Safe to downgrade to: a release before 5.6

1. Check installed version

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

2. No fixed release: DOWNGRADE to a release before 5.6 (Debian / Ubuntu)

apt-cache madison perl sudo apt install perl=<VERSION_BEFORE_5.6> sudo apt-mark hold perl

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

dnf --showduplicates list perl sudo dnf downgrade perl-<VERSION_BEFORE_5.6> sudo dnf versionlock add perl

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.
