For the snom ONE minis, we have a problem updating the bash. It seems that there is no new version available yet. Anyhow, for those who want to give it a try here is what I have tried:
The update gave me an error because obviously some servers have been moved or added. That is why I added those keys to the apt-key list. Then the update actually did realize there is a new bash, and the new bash installation did something. However it seems that the upgrade did not fix the problem yet .
