Thanks, Darac,

It's interesting, because when I tried opening the graph, and it gave me

Software error:

Can't open /var/log/munin/munin-cgi-graph.log (Permission denied) at
/usr/share/perl5/Log/Log4perl/Appender/File.pm line 103.

The file was owned by www-data:adm. So I changed it to munin:adm,
which is what the rest of them were, but I'm still seeing the issue
with the same error message. I have tried setting the permissions on
munin-cgo-graph.log to 777 temporarily. I suspect that I may not have
set it up right, and a straight upgrade did not proceed as expected.
