linuxfoundation yocto DOWNGRADE

Affected: 3.3 · 4.0 · 5.0

Fixed in: no fixed release known

Safe to downgrade to: a release before 3.3

1. Check installed version

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

2. No fixed release: DOWNGRADE to a release before 3.3 (Debian / Ubuntu)

apt-cache madison yocto sudo apt install yocto=<VERSION_BEFORE_3.3> sudo apt-mark hold yocto

2. No fixed release: DOWNGRADE (RHEL / Amazon Linux / Fedora)

dnf --showduplicates list yocto sudo dnf downgrade yocto-<VERSION_BEFORE_3.3> sudo dnf versionlock add yocto

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.

mediatek software development kit UPGRADE

Affected: <= 2.4

Fixed in: newer than 2.4

Safe to downgrade to: no unaffected older release

1. Check installed version

apt-cache policy software-development-kit || rpm -q software-development-kit || software-development-kit --version

2. UPGRADE to newer than 2.4 (Debian / Ubuntu)

sudo apt update && sudo apt install --only-upgrade software-development-kit

2. UPGRADE (RHEL / Amazon Linux / Fedora)

sudo dnf upgrade software-development-kit

Note

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