Hi Michael,
Thanks for looking into the issue. I'm getting almost the exact same
error message. It started a few weeks ago. The issue is reproducible
whether I run unattended-upgrades from the shell or from cron.
File "/usr/bin/unattended-upgrade", line 815, in send_summary_mail
host(), res)
TypeError: unsupported operand type(s) for %: 'bytes' and 'tuple'
This statement is causing the error on my system:
subject = _("unattended-upgrades result for '%s': '%s'") % (host(),
res)
res argument is 'None'. host() is a string. type(_("unattended-upgrades
result for '%s': '%s'")) is <class 'bytes'>. Shouldn't this be string?
My locale is de_DE.UTF-8. gettext on the shell does return a
translation:
# gettext unattended-upgrades "unattended-upgrades result for '%s':
'%s'"
Unattended-Upgrades-Ergebnis für »%s«: %s
If I change the message to be translated, unattended-upgrades continues,
but complains about another _(...) message further down.
Now I'm lost. Any help is greatly appreciated.
Frank
