Hello Guys,
I have tried Ubuntu (finally managed to get it booted) and Debian.
Some packages just won’t install on Ubuntu (ncclient) others (pandas) takes 40 mins to get installed.
Which image do you recommend?
Thanks!
Istvan
What is the best image for Python 3 server?
Hi Istvan_Kelemen,
Installation take a long time because of need to compile. What information is prompted when an installation error occurs?
Try
sudo apt-get install python3-lxml
and reinstall ncclient
Hey,
Unfortunately it did not help.
