apache nuttx UPGRADE

Affected: >= 10.0.0 and < 12.10.0

Fixed in: 12.10.0

Safe to downgrade to: a release before 10.0.0

1. Check installed version

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

2. UPGRADE to 12.10.0 (Debian / Ubuntu)

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

2. UPGRADE (RHEL / Amazon Linux / Fedora)

sudo dnf upgrade nuttx

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 10.0.0 (Debian / Ubuntu)

apt-cache madison nuttx sudo apt install nuttx=<VERSION_BEFORE_10.0.0> sudo apt-mark hold nuttx

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

dnf --showduplicates list nuttx sudo dnf downgrade nuttx-<VERSION_BEFORE_10.0.0> sudo dnf versionlock add nuttx

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.
