google gvisor UPGRADE

Affected: < 20231030.0 · >= 20231106.0 and < 20231204.0

Fixed in: 20231030.0, 20231204.0

Safe to downgrade to: a release before 20231106.0

1. Check installed version

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

2. UPGRADE to 20231030.0 (Debian / Ubuntu)

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

2. UPGRADE (RHEL / Amazon Linux / Fedora)

sudo dnf upgrade gvisor

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 20231106.0 (Debian / Ubuntu)

apt-cache madison gvisor sudo apt install gvisor=<VERSION_BEFORE_20231106.0> sudo apt-mark hold gvisor

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

dnf --showduplicates list gvisor sudo dnf downgrade gvisor-<VERSION_BEFORE_20231106.0> sudo dnf versionlock add gvisor

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.
