davfs2 davfs2 DOWNGRADE

Affected: 0.2.3

Fixed in: no fixed release known

Safe to downgrade to: a release before 0.2.3

1. Check installed version

apt-cache policy davfs2 || rpm -q davfs2 || davfs2 --version

2. No fixed release: DOWNGRADE to a release before 0.2.3 (Debian / Ubuntu)

apt-cache madison davfs2 sudo apt install davfs2=<VERSION_BEFORE_0.2.3> sudo apt-mark hold davfs2

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

dnf --showduplicates list davfs2 sudo dnf downgrade davfs2-<VERSION_BEFORE_0.2.3> sudo dnf versionlock add davfs2

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.
