unctad asycuda world UPGRADE

Affected: >= 2001 and <= 2020

Fixed in: newer than 2020

Safe to downgrade to: a release before 2001

1. Check installed version

apt-cache policy asycuda-world || rpm -q asycuda-world || asycuda-world --version

2. UPGRADE to newer than 2020 (Debian / Ubuntu)

sudo apt update && sudo apt install --only-upgrade asycuda-world

2. UPGRADE (RHEL / Amazon Linux / Fedora)

sudo dnf upgrade asycuda-world

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 2001 (Debian / Ubuntu)

apt-cache madison asycuda-world sudo apt install asycuda-world=<VERSION_BEFORE_2001> sudo apt-mark hold asycuda-world

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

dnf --showduplicates list asycuda-world sudo dnf downgrade asycuda-world-<VERSION_BEFORE_2001> sudo dnf versionlock add asycuda-world

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.
