autodesk revit UPGRADE

Affected: >= 2026 and < 2026.3

Fixed in: 2026.3

Safe to downgrade to: a release before 2026

1. Check installed version

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

2. UPGRADE to 2026.3 (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 2026 (Debian / Ubuntu)

apt-cache madison revit sudo apt install revit=<VERSION_BEFORE_2026> 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_2026> 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.
