gleam-wisp wisp UPGRADE

Affected: >= 0.2.0 and < 2.2.2

Fixed in: 2.2.2

Safe to downgrade to: a release before 0.2.0

1. Check installed version

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

2. UPGRADE to 2.2.2 (Debian / Ubuntu)

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

2. UPGRADE (RHEL / Amazon Linux / Fedora)

sudo dnf upgrade wisp

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 0.2.0 (Debian / Ubuntu)

apt-cache madison wisp sudo apt install wisp=<VERSION_BEFORE_0.2.0> sudo apt-mark hold wisp

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

dnf --showduplicates list wisp sudo dnf downgrade wisp-<VERSION_BEFORE_0.2.0> sudo dnf versionlock add wisp

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.
