eclipse sphinx UPGRADE

Affected: >= 0.7.0 and < 0.13.1

Fixed in: 0.13.1

Safe to downgrade to: a release before 0.7.0

1. Check installed version

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

2. UPGRADE to 0.13.1 (Debian / Ubuntu)

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

2. UPGRADE (RHEL / Amazon Linux / Fedora)

sudo dnf upgrade sphinx

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 0.7.0 (Debian / Ubuntu)

apt-cache madison sphinx sudo apt install sphinx=<VERSION_BEFORE_0.7.0> sudo apt-mark hold sphinx

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

dnf --showduplicates list sphinx sudo dnf downgrade sphinx-<VERSION_BEFORE_0.7.0> sudo dnf versionlock add sphinx

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.
