accellion kiteworks UPGRADE

Affected: >= 9.3.0 and < 9.5.1

Fixed in: 9.5.1

Safe to downgrade to: a release before 9.3.0

1. Check installed version

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

2. UPGRADE to 9.5.1 (Debian / Ubuntu)

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

2. UPGRADE (RHEL / Amazon Linux / Fedora)

sudo dnf upgrade kiteworks

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 9.3.0 (Debian / Ubuntu)

apt-cache madison kiteworks sudo apt install kiteworks=<VERSION_BEFORE_9.3.0> sudo apt-mark hold kiteworks

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

dnf --showduplicates list kiteworks sudo dnf downgrade kiteworks-<VERSION_BEFORE_9.3.0> sudo dnf versionlock add kiteworks

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.
