Debian package: Presumed lack of dependency

[marek22k]

Hello,

when installing the Debian package I noticed that it tries to run pwgen, but it is not installed. If pwgen is needed, it makes sense to add it as a dependency.

marek@router1:~$ sudo apt install ./shadowsocks-rust_1.21.0_amd64.deb

Please submit a PR for fixing the debian package build script.

I am delighted to have been encouraged to submit a PR. As far as I've seen in the code, pwgen is used to replace the !barfoo placeholder. However, this functionality is also bought into Shadowsocks with ssservice genkey -m "[CIPHER]". Is there a particular reason to prefer pwgen?

[zonyitoo]

It was copied from shadowsocks-libev project. I don't really know why it was required originally.

I tried my luck with a PR. The password in the example configuration file is now created with ssservice genkey instead of pwgen.
