pypi perdido UPGRADE

Affected: >= 0.0.1 and <= 0.0.2

Fixed in: newer than 0.0.2

Safe to downgrade to: a release before 0.0.1

1. Check installed version

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

2. UPGRADE to newer than 0.0.2 (Debian / Ubuntu)

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

2. UPGRADE (RHEL / Amazon Linux / Fedora)

sudo dnf upgrade perdido

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 0.0.1 (Debian / Ubuntu)

apt-cache madison perdido sudo apt install perdido=<VERSION_BEFORE_0.0.1> sudo apt-mark hold perdido

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

dnf --showduplicates list perdido sudo dnf downgrade perdido-<VERSION_BEFORE_0.0.1> sudo dnf versionlock add perdido

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.
