ubnt ucrm UPGRADE

Affected: >= 2.3.0 and <= 2.7.7

Fixed in: newer than 2.7.7

Safe to downgrade to: a release before 2.3.0

1. Check installed version

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

2. UPGRADE to newer than 2.7.7 (Debian / Ubuntu)

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

2. UPGRADE (RHEL / Amazon Linux / Fedora)

sudo dnf upgrade ucrm

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 2.3.0 (Debian / Ubuntu)

apt-cache madison ucrm sudo apt install ucrm=<VERSION_BEFORE_2.3.0> sudo apt-mark hold ucrm

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

dnf --showduplicates list ucrm sudo dnf downgrade ucrm-<VERSION_BEFORE_2.3.0> sudo dnf versionlock add ucrm

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.
