openmix mix php UPGRADE

Affected: >= 2.0.1 and <= 2.2.17

Fixed in: newer than 2.2.17

Safe to downgrade to: a release before 2.0.1

1. Check installed version

apt-cache policy mix-php || rpm -q mix-php || mix-php --version

2. UPGRADE to newer than 2.2.17 (Debian / Ubuntu)

sudo apt update && sudo apt install --only-upgrade mix-php

2. UPGRADE (RHEL / Amazon Linux / Fedora)

sudo dnf upgrade mix-php

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 2.0.1 (Debian / Ubuntu)

apt-cache madison mix-php sudo apt install mix-php=<VERSION_BEFORE_2.0.1> sudo apt-mark hold mix-php

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

dnf --showduplicates list mix-php sudo dnf downgrade mix-php-<VERSION_BEFORE_2.0.1> sudo dnf versionlock add mix-php

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.
