Hi @magneticstripper !

Did you read this?

> We strongly recommend you to **download and burn the new SD image.** Trying to upgrade from previous stable version is a long and error prone process so we have decided to block it to avoid people’s complains. Old stable version can’t be upgraded!

> Hi @zynthianers! The new stable version is out! It’s been a long way and many things have changed, so be prepared to enjoy. Here is the download link: [https://os.zynthian.org/zynthianos-last-stable.zip](https://os.zynthian.org/zynthianos-last-stable.zip) We strongly recommend you to download and burn the new SD image. Trying to upgrade from previous stable version is a long and error prone process so we have decided to block it to avoid people’s complains. Old stable version can’t be upgraded! Of course, if you already downloaded a staging-221…

Old stable images are not updatable. You have to download & burn a new image.

Regards!
