Fixed in: 10.4, 10.11

Safe to downgrade to: a release before 10.4

1. Check installed version

apt-cache policy web-services || rpm -q web-services || web-services --version

2. UPGRADE to 10.4 (Debian / Ubuntu)

sudo apt update && sudo apt install --only-upgrade web-services

2. UPGRADE (RHEL / Amazon Linux / Fedora)

sudo dnf upgrade web-services

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 10.4 (Debian / Ubuntu)

apt-cache madison web-services sudo apt install web-services=<VERSION_BEFORE_10.4> sudo apt-mark hold web-services

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

dnf --showduplicates list web-services sudo dnf downgrade web-services-<VERSION_BEFORE_10.4> sudo dnf versionlock add web-services

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.
