zetacomponents mvctools DOWNGRADE

Affected: 2008-09-23

Fixed in: no fixed release known

Safe to downgrade to: a release before 2008-09-23

1. Check installed version

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

2. No fixed release: DOWNGRADE to a release before 2008-09-23 (Debian / Ubuntu)

apt-cache madison mvctools sudo apt install mvctools=<VERSION_BEFORE_2008-09-23> sudo apt-mark hold mvctools

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

dnf --showduplicates list mvctools sudo dnf downgrade mvctools-<VERSION_BEFORE_2008-09-23> sudo dnf versionlock add mvctools

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.
