kilo kilo code UPGRADE

Affected: >= 7.0.0 and <= 7.0.47

Fixed in: newer than 7.0.47

Safe to downgrade to: a release before 7.0.0

1. Check installed version

apt-cache policy kilo-code || rpm -q kilo-code || kilo-code --version

2. UPGRADE to newer than 7.0.47 (Debian / Ubuntu)

sudo apt update && sudo apt install --only-upgrade kilo-code

2. UPGRADE (RHEL / Amazon Linux / Fedora)

sudo dnf upgrade kilo-code

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 kilo-code sudo apt install kilo-code=<VERSION_BEFORE_7.0.0> sudo apt-mark hold kilo-code

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

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

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.
