freedesktop libinput UPGRADE

Affected: < 1.30.4 · >= 1.31.0 and < 1.31.3

Fixed in: 1.30.4, 1.31.3

Safe to downgrade to: a release before 1.31.0

1. Check installed version

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

2. UPGRADE to 1.30.4 (Debian / Ubuntu)

sudo apt update && sudo apt install --only-upgrade libinput

2. UPGRADE (RHEL / Amazon Linux / Fedora)

sudo dnf upgrade libinput

Note

Distros often backport fixes without changing the version number. Confirm with the distro advisory or changelog.

3. If no update is available yet, DOWNGRADE to a release before 1.31.0 (Debian / Ubuntu)

apt-cache madison libinput sudo apt install libinput=<VERSION_BEFORE_1.31.0> sudo apt-mark hold libinput

3. If no update is available yet, DOWNGRADE (RHEL / Amazon Linux / Fedora)

dnf --showduplicates list libinput sudo dnf downgrade libinput-<VERSION_BEFORE_1.31.0> sudo dnf versionlock add libinput

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.
