energycap energycap UPGRADE

Affected: >= 7.0.0 and <= 7.5.6

Fixed in: newer than 7.5.6

Safe to downgrade to: a release before 7.0.0

1. Check installed version

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

2. UPGRADE to newer than 7.5.6 (Debian / Ubuntu)

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

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 7.0.0 (Debian / Ubuntu)

apt-cache madison energycap sudo apt install energycap=<VERSION_BEFORE_7.0.0> sudo apt-mark hold energycap

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

dnf --showduplicates list energycap sudo dnf downgrade energycap-<VERSION_BEFORE_7.0.0> sudo dnf versionlock add energycap

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.
