 Nyx is not starting up after providing the control port password it
 reports:

 {{{
 % nyx
 Tor controller password:

 During handling of the above exception, another exception occurred:

 }}}

 If the wrong password is provided I get the usual answer:
 {{{
 % nyx
 Tor controller password:
 Incorrect password
 }}}

 These are the used software versions

 {{{
 % python --version
 Python 3.8.0
 }}}

 {{{
 % nyx --version
 nyx version 2.1.0 (released January 12, 2019)
 }}}

 {{{
 % uname -a
 Linux archarm 4.19.84-1-ARCH #1 SMP PREEMPT Thu Nov 21 00:50:40 UTC 2019
 armv7l GNU/Linux
 }}}

 I also get the same error with archlinux x86_64 (kernel 5.3.12) with the
 same python and nyx versions
