Errors while installing strongMan on macOS

[matteocarnelos]

Hi, I'm trying to install strongMan on macOS Ventura, but when I run:

sudo ./setup.py install

I get the following errors:

During handling of the above exception, another exception occurred:

Context

• macOS version: 13.6 (Ventura)
• Python version: 3.10.11
• strongSwan version: 5.9.11
• Pip version: 23.1.2
• Git version: 2.39.3
• Virtualenv version: 20.24.5

Please try changing this: https://github.com/strongswan/strongMan/blob/3934ad3bf53da0d70b1ad52f44db5a9fc7742073/requirements.txt#L2

to oscrypto==1.3.0.

[matteocarnelos]

Unfortunately it results in dependency conflicts:

Start strongMan installation
    - Virtualenv
    - Requirements

ERROR: Cannot install -r requirements.txt (line 2) and asn1crypto==1.4.0 because these package versions have conflicting dependencies.

Update

Bumping asn1crypto version to 1.5.0 in requirements.txt solves the dependency conflict but results in the original error messages.

[tobiasbrunner]

Which original error message are you referring to?

[matteocarnelos]

I meant the one posted at the beginning.

However, I managed to solve the issue by bumping the version number of oscrypto to 1.3.0 and asn1crypto to 1.5.1. Now the installation goes through successfully, thanks!

[tobiasbrunner]

OK, great, I'll push that to master soon.
