redhat interchange UPGRADE

Affected: >= 4.7.0 and < 5.12.0

Fixed in: 5.12.0

Safe to downgrade to: a release before 4.7.0

1. Check installed version

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

2. UPGRADE to 5.12.0 (Debian / Ubuntu)

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

2. UPGRADE (RHEL / Amazon Linux / Fedora)

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 4.7.0 (Debian / Ubuntu)

apt-cache madison interchange sudo apt install interchange=<VERSION_BEFORE_4.7.0> sudo apt-mark hold interchange

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

dnf --showduplicates list interchange sudo dnf downgrade interchange-<VERSION_BEFORE_4.7.0> sudo dnf versionlock add interchange

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.
