Affected: >= 20.2 and < 21.3.7.18607

Fixed in: 21.3.7.18607

Safe to downgrade to: a release before 20.2

1. Check installed version

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

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 20.2 (Debian / Ubuntu)

apt-cache madison filecloud sudo apt install filecloud=<VERSION_BEFORE_20.2> sudo apt-mark hold filecloud

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

dnf --showduplicates list filecloud sudo dnf downgrade filecloud-<VERSION_BEFORE_20.2> sudo dnf versionlock add filecloud

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.
