Fixed in: 2022.1.5, 2023.1.6, 2024.1.5, 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
