How to find out version of Turris OS on your router?⚓︎

Using SSH⚓︎

You can connect to your router using SSH and view file /etc/os-release. The easiest option is to just simply print it to console with cat /etc/os-release.

Alternatively for script usage you can source /etc/os-release and use variable $(VERSION_ID}. Example follows:

. /etc/os-release
echo "${VERSION_ID}"

Versions of Turris OS provided from factory⚓︎

When Turris routers are shipped from factory they are provided with stable version of Turris OS at that time. When you unpack new router or when you reset it to factory settings then it is running Turris OS of that exact version (unless medkit is used).

These versions have special form of support. For generic version there is limited window of time when update is guaranteed. Updates from old versions can possibly be problematic and Turris team can’t ensure compatibility with every single released version in past. The exception are factory versions. Updates from those should work and be tested in scope of base install (no additional packages).


Although factory versions are supported and update path tested it might not be smooth simply because of possibly long update or problems during update Turris team can’t do anything about. For best experience it is advised to always reflash router from flash drive/SD card with latest version of Turris OS.

Deprecation of⚓︎

Old versions of Turris OS (up to 3.x) supported the portal. It provided information about threats detected by users’ routers using the old data collection system Ucollect.

Because of migration to the new security solution called Turris Sentinel, new versions of Turris OS (4.0 and newer) are no longer compatible with the mentioned portal. You can find various threat statistics on our new web Sentinel:view.

The portal itself has been archived and is available only as a static website. No new data from routers is processed here; all historical data has been dropped.

  1. Turris 1.x were originally sent out with Turris OS versions before 3.0 but because of DNS root key rollover there was a need to force update factory version in all of those routers. This happened with Turris OS 3.11. With this change Turris 1.x is considered to contain factory version Turris OS 3.8.5. Originally there was one more significant version of Turris OS for Turris 1.x and that was 3.7.3. This version was used to migrate from previous updater to updater-ng. With factory update to 3.8.5 it is no longer relevant.
