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 2026.2.4.0 (Debian / Ubuntu)

apt-cache madison devolutions-server sudo apt install devolutions-server=<VERSION_BEFORE_2026.2.4.0> sudo apt-mark hold devolutions-server

dnf --showduplicates list devolutions-server sudo dnf downgrade devolutions-server-<VERSION_BEFORE_2026.2.4.0> sudo dnf versionlock add devolutions-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.
