Dear maintainer,I am also experiencing this issue. I am on stable and speedtest-cli is 0.3.1-1.
I do not have any Python-style error output like Francesco, only this:
$ speedtest-cli Retrieving speedtest.net configuration... Retrieving speedtest.net server list... Failed to parse list of speedtest.net serversPlease backport a fix to stable, otherwise this application is essentially useless on stable. Thank you.
