autodesk maya DOWNGRADE

Affected: 2023

Fixed in: no fixed release known

Safe to downgrade to: a release before 2023

1. Check installed version

apt-cache policy maya || rpm -q maya || maya --version

2. No fixed release: DOWNGRADE to a release before 2023 (Debian / Ubuntu)

apt-cache madison maya sudo apt install maya=<VERSION_BEFORE_2023> sudo apt-mark hold maya

2. No fixed release: DOWNGRADE (RHEL / Amazon Linux / Fedora)

dnf --showduplicates list maya sudo dnf downgrade maya-<VERSION_BEFORE_2023> sudo dnf versionlock add maya

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.
