Hello, I wonder if this issue(https://gitlab.com/ mailman/mailman/issues/3) was fixed?

It was fixed actually, but it might be a problem when the files aren't installed int the bin directory specified in the configuration.

...

I try to set up a mailing list on aws ec2(ubuntu). In the instruction( http://docs.mailman3.org/en/latest/prodsetup.html), it doesn't require to install mailman in a virtual env. However, when I tried to run mailman start, it produces /usr/bin/python3: can't open file '/usr/bin/master': [Errno 2] No such file or directory.

Can you show us the contents of mailman.cfg that you are using?

[paths.custom] var_dir: /home/ubuntu/mailman bin_dir: /sbin queue_dir: /var/spool/mailman log_dir: /var/log/mailman lock_dir: /var/lock/mailman etc_dir: /etc ext_dir: /etc/mailman.d pid_file: /var/run/mailman/master.pid

[mailman] layout: custom

Exception: /usr/bin/python3: can't open file '/sbin/master': [Errno 2] No such file or directory

If you are using [paths.fhs], then I guess I can imagine why this is a problem.

@Barry: Is is wrong for the [paths.fhs] to set the bin_dir? No other paths configuration does this.

When you install using any tool like pip, the console scripts usually land in /usr/local/bin or /usr/bin depending on the distro, but using the [paths.fhs] doesn't work in these cases because the scripts are not in /sbin and hence the error as presented above.

thanks, Abhilash Raj

All the other path configs calculate their bin_dir based on sys.executable. In config.py:

    default_bin_dir = os.path.abspath(os.path.dirname(sys.executable))
…
substitutions = dict(
    …
    argv=default_bin_dir,

and from schema.cfg:

# This is the directory containing the Mailman 'runner' and 'master' commands # if set to the string '$argv', it will be taken as the directory containing # the 'mailman' command. bin_dir: $argv

However, I think for paths.fhs, it is correct to hardcode bin_dir to /sbin (although perhaps it should be /usr/sbin now).

http://www.pathname.com/fhs/pub/fhs-2.3.html#SBINSYSTEMBINARIES

paths.fhs very specifically expects things to be laid out according to the FHS.
