digiwin easyflow .net UPGRADE

Affected: >= 6.6.0 and <= 6.6.17 · 6.1.0 · 8.1.1 · 8.1.2

Fixed in: newer than 6.6.17

Safe to downgrade to: a release before 6.1.0

1. Check installed version

apt-cache policy easyflow-.net || rpm -q easyflow-.net || easyflow-.net --version

2. UPGRADE to newer than 6.6.17 (Debian / Ubuntu)

sudo apt update && sudo apt install --only-upgrade easyflow-.net

2. UPGRADE (RHEL / Amazon Linux / Fedora)

sudo dnf upgrade easyflow-.net

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 6.1.0 (Debian / Ubuntu)

apt-cache madison easyflow-.net sudo apt install easyflow-.net=<VERSION_BEFORE_6.1.0> sudo apt-mark hold easyflow-.net

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

dnf --showduplicates list easyflow-.net sudo dnf downgrade easyflow-.net-<VERSION_BEFORE_6.1.0> sudo dnf versionlock add easyflow-.net

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.
