icoasoft potrace DOWNGRADE

Affected: 1.11

Fixed in: no fixed release known

Safe to downgrade to: a release before 1.11

1. Check installed version

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

2. No fixed release: DOWNGRADE to a release before 1.11 (Debian / Ubuntu)

apt-cache madison potrace sudo apt install potrace=<VERSION_BEFORE_1.11> sudo apt-mark hold potrace

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

dnf --showduplicates list potrace sudo dnf downgrade potrace-<VERSION_BEFORE_1.11> sudo dnf versionlock add potrace

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.
