autodesk autocad UPGRADE
Affected: >= 2022 and < 2022.1.5 · >= 2023 and < 2023.1.6 · >= 2024 and < 2024.1.4 · >= 2025 and < 2025.1
Fixed in: 2022.1.5, 2023.1.6, 2024.1.4, 2025.1
Safe to downgrade to: a release before 2022
1. Check installed version
apt-cache policy autocad || rpm -q autocad || autocad --version
2. UPGRADE to 2022.1.5 (Debian / Ubuntu)
sudo apt update && sudo apt install --only-upgrade autocad
2. UPGRADE (RHEL / Amazon Linux / Fedora)
sudo dnf upgrade autocad
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 2022 (Debian / Ubuntu)
apt-cache madison autocad
sudo apt install autocad=<VERSION_BEFORE_2022>
sudo apt-mark hold autocad
3. If no update is available yet, DOWNGRADE (RHEL / Amazon Linux / Fedora)
dnf --showduplicates list autocad
sudo dnf downgrade autocad-<VERSION_BEFORE_2022>
sudo dnf versionlock add autocad
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.
