autodesk autocad map 3d 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-map-3d || rpm -q autocad-map-3d || autocad-map-3d --version

2. UPGRADE to 2022.1.5 (Debian / Ubuntu)

sudo apt update && sudo apt install --only-upgrade autocad-map-3d

2. UPGRADE (RHEL / Amazon Linux / Fedora)

sudo dnf upgrade autocad-map-3d

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-map-3d sudo apt install autocad-map-3d=<VERSION_BEFORE_2022> sudo apt-mark hold autocad-map-3d
