[SOLVED] Removing a dependency in Python

Hello,

a Wapt Enterprise
version of Wapt 2.4.14.143,
server = Debian, and
package creation PC = Windows 10.

I would like to know if it's possible to remove a package from its dependencies within a Python script?

For example:
A = condition,
B = package name,
C = hostname.
If condition A is true, then
remove B from C.

I've searched using wapt-get, but I haven't found anything.

Thank you in advance for your help.

Hello Benoit,

The best approach in this kind of situation is to create a meta-package and avoid dependencies, and in that case, you're free to do whatever you want

example :

Code: Select all

# -*- coding: utf-8 -*-
from setuphelpers import *

def install():

    hostname = get_computername().lower()


    # Si les 4 dernier caractères du poste sont "prof" alors j'installe Firefox ESR
    if hostname.endswith('prof') :
        WAPT.install('tis-firefox-esr')

    if 'eleves' in hostname :
        if WAPT.is_installed('tis-gestionnote') :
            WAPT.remove('tis-gestionnote')

    if installed_softwares('Mozilla Firefox') :
        WAPT.install('tis-firefox-esr')

    # Si la manufacture du poste est 'innotek GmbH', installer le paquet drivers smp-drivers-for-innotek
    if wmi_info_basic()["System_Information"]["Manufacturer"] == 'innotek GmbH' :
        WAPT.install('tis-drivers-for-innotek')

    unitorga = registry_readstring(HKEY_LOCAL_MACHINE, r'SOFTWARE\Microsoft\Windows\CurrentVersion\Group Policy\State\Machine', 'Distinguished-Name')
    
    if 'OU=Ordinateur_compta,OU=Ordinateur_administratif,DC=tranquilit,DC=local' in unitorga :
        WAPT.install('tis-libreoffice-stable')


    if 'mongroup' in get_computer_groups():
        WAPT.install('tis-group')

Thank you for your reply, but that's not what I'm trying to do:

Here is the setup I'm posing for here:

                print(f"Une version pro de l'application {name_app} est déjà installée.\nCette version ne sera donc pas déployé sur ce poste")
                pro =True
                break
        if not pro:
            uninstall()
            install_app()            
    except Exception as e :

I would like that if "pro" is true, then this package should be removed from the dependencies of the PC for which pro is true.

Hello Benoit,

Impossible, the dependency is at the package level, so it will come back...

You need to create a meta package for Adobe Reader:

tis-adboe-reader

and in the package something like this:

Code: Select all

def install():
    if installed_software('adobe reader pro'):
        WAPT.install('tis-adboe-reader-pro')
    else
        WAPT.install('tis-adboe-reader-normal')

Thank you for your reply.

If I understand correctly, it's impossible to remove a package from a PC's dependencies using the command line?

Regards,

Hi Benoit,

No, the PC can't edit the packages (remove a dependency) because it doesn't have your private key.
