opennav nav2 UPGRADE

Affected: >= 1.1.0 and <= 1.1.17

Fixed in: newer than 1.1.17

Safe to downgrade to: a release before 1.1.0

1. Check installed version

apt-cache policy nav2 || rpm -q nav2 || nav2 --version

2. UPGRADE to newer than 1.1.17 (Debian / Ubuntu)

sudo apt update && sudo apt install --only-upgrade nav2

2. UPGRADE (RHEL / Amazon Linux / Fedora)

sudo dnf upgrade nav2

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 1.1.0 (Debian / Ubuntu)

apt-cache madison nav2 sudo apt install nav2=<VERSION_BEFORE_1.1.0> sudo apt-mark hold nav2

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

dnf --showduplicates list nav2 sudo dnf downgrade nav2-<VERSION_BEFORE_1.1.0> sudo dnf versionlock add nav2

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.

Safe to downgrade to: a release before 2

Check your OS release

cat /etc/os-release; uname -r

Debian / Ubuntu

sudo apt update && sudo apt full-upgrade

RHEL / Amazon Linux / Fedora

sudo dnf upgrade --refresh

Windows

Install the latest cumulative update from Windows Update
