Subject: pg_activity fails with TypeError on start

Message-ID: <[email protected]> (raw)

Hi,

OS: Devuan beowulf (equivalent to Debian buster)

Package: pg-activity=2.1.0-1.pgdg100+1

I have the latest version of pg-activity installed from the buster-pgdg 
repository and it fails on startup with a TypeError.

$ pg_activity 
Traceback (most recent call last):
  File "/usr/bin/pg_activity", line 321, in <module>
    ui.main(term, dataobj, host, options, dsn)
  File "/usr/lib/python3/dist-packages/pgactivity/ui.py", line 227, in

I can see in the package information that the upstream source is listed
as https://github.com/julmon/pg_activity.  That repository mentions
that it is a fork of the original upstream at 
https://github.com/dalibo/pg_activity.

I have tested the latest version of pg_activity 2.1.5 from 
https://github.com/dalibo/pg_activity installed via pip in a python3.7
virtual environment and it starts properly without any error.

Can the pg-activity package please be updated to the latest version
2.1.5 from https://github.com/dalibo/pg_activity?

Thanks,
Tom
