Affected: 1.0a

Fixed in: no fixed release known

Safe to downgrade to: a release before 1.0a

1. Check installed version

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

2. No fixed release: DOWNGRADE to a release before 1.0a (Debian / Ubuntu)

apt-cache madison axel sudo apt install axel=<VERSION_BEFORE_1.0a> sudo apt-mark hold axel

dnf --showduplicates list axel sudo dnf downgrade axel-<VERSION_BEFORE_1.0a> sudo dnf versionlock add axel

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.
