I don't think that should happen.

@IndexOutOfMJ On with distribution are you trying to install modoboa? Have you tried using the --debug option?

I'll leave this for anyone else whom runs into the same issue as it was not immediately apparent as to the cause. I ran into the same issue on a fresh Debian 11 install when running as root (not sudo). I found that this would fail with the error FileNotFoundError: [Errno 2] No such file or directory: '/srv/modoboa'. When using --debug I could see the install failed silently in the background to find the service command and then spat out the error [Errno 2] No such file or directory: '/srv/modoboa'.

The issue was that the PATH variable did not include sbin paths, ie /sbin, /usr/sbin, /usr/local/sbin. By adding these to PATH I was able to install without issue, ie export PATH=$PATH:/sbin:/usr/sbin:/usr/local/sbin.

I have exactly the same error. I am also using Debian 11.
Programs in sbin, such as useradd are not found.
But if I change to root with "su -", the minus sign is important, it finds programs under /sbin/ and the installer runs through.

Is this a normal behavior, or a bug in Debian or a bug in the installer?

@ecsgh It's a normal behaviour. The - sign (or -i option with sudo) tells the command to load the target user environment variables. If you do not specify those options, then the environment of the original user is used. With a regular user, the PATH variable won't include /sbin and /usr/sbin folders.

Yes I know what "-" does.
But I think that should be taken into the documentation, because as it currently stands in it, the installation just does not work.
