google chrome UPGRADE

Affected: < 103.0.5060.114

Fixed in: 103.0.5060.114

Safe to downgrade to: no unaffected older release

1. Check installed version

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

2. UPGRADE to 103.0.5060.114 (Debian / Ubuntu)

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

2. UPGRADE (RHEL / Amazon Linux / Fedora)

sudo dnf upgrade chrome

Note

Distros often backport fixes without changing the version number. Confirm with the distro advisory or changelog.

fedoraproject extra packages for enterprise linux DOWNGRADE

Affected: 8.0

Fixed in: no fixed release known

Safe to downgrade to: a release before 8.0

1. Check installed version

apt-cache policy extra-packages-for-enterprise-linux || rpm -q extra-packages-for-enterprise-linux || extra-packages-for-enterprise-linux --version

2. No fixed release: DOWNGRADE to a release before 8.0 (Debian / Ubuntu)

apt-cache madison extra-packages-for-enterprise-linux sudo apt install extra-packages-for-enterprise-linux=<VERSION_BEFORE_8.0> sudo apt-mark hold extra-packages-for-enterprise-linux

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.
