Subject: bug#42068: CUPS :631/admin interface freezes
Date: Fri, 26 Jun 2020 23:18:26 +0200

[Message part 1 (text/plain, inline)]

Guix,

When visiting localhost:631/admin, the server appears to freeze 
(blank page).  However, exactly 2 minutes later content is served 
and buttons like ‘Find New Printer’ [appear to] work without 
delay.

Some error_log debug output below.  Note the 2 neat 1-minute 
time-outs.

It's likely that this is an upstream bug (but not quite this [1]). 
I'll try upgrading CUPS and gathering more infos.

Kind regards,

T G-R
