Webmin is a web-based interface that allows Unix-like operating
systems and common Unix services to be easily administered.

Webmin uses separate directories for configuration files and log files.
Unless you want to run multiple versions of Webmin at the same time
you can just accept the defaults.

Looks like a perl script bug of some sort; perl is perl 5, version 26, subversion 1 (v5.26.1) built for x86_64-netbsd-thread-multi

[Bruce Lilly]

The bug is actually in setup.sh, which uses an unset variable; the fix is a one-liner:

    # Get current perl path
    perl=`cat $config_dir/perl-path`

• if [ -z "$perl" ]; then perl=perl ; fi

  # Create temp files directory
  $perl "$srcdir/maketemp.pl"
  

[Bruce Lilly]

Well, that sort of worked; setup runs but the server fails because the perl scripts puke if there's not a full path.

So perl=type -p perl | awk '{print $NF}'

That installs and runs, but the server just spits out a message about a missing Content-Type field.

I'm back to 1.820 here.

[Jamie Cameron]

SO it looks like an existijng Webmin install was found, but it was somehow incomplete? Was this an upgrade, or a new install?

[Bruce Lilly]

1.820 may have been installed from a package, or may have been an upgrade; I don't remember.

[Bruce Lilly]

Copying/generating missing files (perl-path, var-path, miniserv.pem) from another system allows an upgrade to work.

The setup script should probably generate appropriate content if these files are missing instead of blindly proceeding.

[Jamie Cameron]

Yeah, it assumes that if the config directory exists and contains a file called config that it can be upgraded.

[Jamie Cameron]

But in the next release, I will add extra checks for all the important config files.
