Fixed in: 2024.3.5, 2025.4.5, 2026.4.1, 2027.1

Safe to downgrade to: a release before 2024

1. Check installed version

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

2. UPGRADE to 2024.3.5 (Debian / Ubuntu)

sudo apt update && sudo apt install --only-upgrade revit

2. UPGRADE (RHEL / Amazon Linux / Fedora)

sudo dnf upgrade revit

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 2024 (Debian / Ubuntu)

apt-cache madison revit sudo apt install revit=<VERSION_BEFORE_2024> sudo apt-mark hold revit

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

dnf --showduplicates list revit sudo dnf downgrade revit-<VERSION_BEFORE_2024> sudo dnf versionlock add revit

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.
