john bradley xv DOWNGRADE

Affected: 3.10a

Fixed in: no fixed release known

Safe to downgrade to: a release before 3.10a

1. Check installed version

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

2. No fixed release: DOWNGRADE to a release before 3.10a (Debian / Ubuntu)

apt-cache madison xv sudo apt install xv=<VERSION_BEFORE_3.10a> sudo apt-mark hold xv

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

dnf --showduplicates list xv sudo dnf downgrade xv-<VERSION_BEFORE_3.10a> sudo dnf versionlock add xv

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.
