autodesk 3ds max UPGRADE

Affected: >= 2026 and < 2026.3.4 · >= 2027 and < 2027.2

Fixed in: 2026.3.4, 2027.2

Safe to downgrade to: a release before 2026

1. Check installed version

apt-cache policy 3ds-max || rpm -q 3ds-max || 3ds-max --version

2. UPGRADE to 2026.3.4 (Debian / Ubuntu)

sudo apt update && sudo apt install --only-upgrade 3ds-max

2. UPGRADE (RHEL / Amazon Linux / Fedora)

sudo dnf upgrade 3ds-max

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 2026 (Debian / Ubuntu)

apt-cache madison 3ds-max sudo apt install 3ds-max=<VERSION_BEFORE_2026> sudo apt-mark hold 3ds-max

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

dnf --showduplicates list 3ds-max sudo dnf downgrade 3ds-max-<VERSION_BEFORE_2026> sudo dnf versionlock add 3ds-max

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.
