The munin package uses autopkgtests. One of the tested scenarios is the switch to the CGI-based rendering. The preparations for this step are quite trivial: * change the strategies to "cgi" * toggle the enabled line in the apache configuration (as documented there) (see https://salsa.debian.org/debian/munin/-/blob/debian/debian/tests/enable_cgi_strategy.inc) Afterwards it should work. At least the current tests do not fail ... The permissions should be handled automatically during package installation: touch /var/log/munin/munin-cgi-html.log chown www-data:adm /var/log/munin/munin-cgi-html.log chmod 640 /var/log/munin/munin-cgi-html.log touch /var/log/munin/munin-cgi-graph.log chown www-data:adm /var/log/munin/munin-cgi-graph.log chmod 640 /var/log/munin/munin-cgi-graph.log mkdir -p /var/lib/munin/cgi-tmp chown munin:www-data /var/lib/munin/cgi-tmp chmod 775 /var/lib/munin/cgi-tmp (see the postinst script) Maybe you are cleaning up the log directory (e.g. on a read-only system) during a reboot? In this case it would indeed fail. I guess, it would be nice for the package to also work in such situations (e.g. non-permantent /var/log/). Or do you have another idea, what could be wrong? Cheers, Lars
