Chia Version 1.1.6 (raspbery pi 4) error

[pm-alonso]

Hello,

I have just installed the new version in my raspberry pi 4. (previous version was 1.1.5 and was working perfectly)
after fresh install (tried two times) I keep getting this error when doing:

. ./activate
chia start farmer.

---

few more details:

~/.chia folder has not been altered in any way.

chia init
Chia directory /home/pi/.chia/mainnet
/home/pi/.chia/mainnet already exists, no migration action taken

chia version
1.1.6

---------- screen error output ---------------

During handling of the above exception, another exception occurred:

Hope someone can help, until fixed my node will stay down.
