rubyonrails globalid UPGRADE

Affected: >= 0.2.1 and < 1.0.1

Fixed in: 1.0.1

Safe to downgrade to: a release before 0.2.1

1. Check installed version

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

2. UPGRADE to 1.0.1 (Debian / Ubuntu)

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

2. UPGRADE (RHEL / Amazon Linux / Fedora)

sudo dnf upgrade globalid

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 0.2.1 (Debian / Ubuntu)

apt-cache madison globalid sudo apt install globalid=<VERSION_BEFORE_0.2.1> sudo apt-mark hold globalid

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

dnf --showduplicates list globalid sudo dnf downgrade globalid-<VERSION_BEFORE_0.2.1> sudo dnf versionlock add globalid

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.
