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 25.8.15085.13 (Debian / Ubuntu)

apt-cache madison m-files-server sudo apt install m-files-server=<VERSION_BEFORE_25.8.15085.13> sudo apt-mark hold m-files-server

dnf --showduplicates list m-files-server sudo dnf downgrade m-files-server-<VERSION_BEFORE_25.8.15085.13> sudo dnf versionlock add m-files-server

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.
