If you are connecting to the network, running the sudo /opt/Citrix/VDA/bin/xdping or /opt/Citrix/VDA/sbin/enable_ldaps.sh command can create a Python3 virtual environment. However, if the commands fail to create a Python3 virtual environment, you can create it manually even without a network connection. This article details the prerequisites and steps to create a Python3 virtual environment without a network connection.

Prerequisites

You must have administrative privileges to access the /opt/Citrix/VDA/sbin/ctxpython3 directory.
The wheel files of Python3 packages are in place. You can download the wheel files from https://pypi.org/.

Create a Python3 virtual environment

Complete the following steps to create a Python3 virtual environment:

Install Python3 dependencies.

For RHEL:
```
yum -y install python36-devel krb5-devel gcc

```
Note:

You might have to enable a particular repository to install some dependencies. For RHEL 7, run the subscription-manager repos --enable rhel-7-server-optional-rpms command. For RHEL 8, run the subscription-manager repos --enable=rhel-8-for-x86_64-appstream-rpms command.

For Ubuntu, Debian:
```
apt-get -y install python3-dev python3-pip python3-venv libkrb5-dev

```
For SUSE:
```
zypper -i -n install python3-devel python3-setuptools krb5-devel gcc libffi48-devel

```
Note:

You might have to enable the SUSE_Linux_Enterprise_Software_Development_Kit_12_SP5_x86_64 repository to install some dependencies.

Note:

To address SSL connection errors that you might encounter when using the pip tool, consider adding the following trusted hosts to the /etc/pip.conf file:
[global]
trusted-host =
pypi.org
files.pythonhosted.org

For RHEL, Ubuntu, Debian:
```
sudo python3 -m venv /opt/Citrix/VDA/sbin/ctxpython3

```
For SUSE:
```
sudo python3 -m venv /opt/Citrix/VDA/sbin/ctxpython3

sudo /opt/Citrix/VDA/sbin/ctxpython3/bin/python3 -m pip install setuptools==40.6.2

```

Install LDAPS dependencies.

For RHEL, Ubuntu, Debian:

sudo /opt/Citrix/VDA/sbin/ctxpython3/bin/python3 -m pip install cffi==1.14.2 cryptography==3.1 decorator==4.4.2 gssapi==1.6.2 ldap3==2.8.1 netifaces==0.10.9 pg8000==1.17.0 psutil==5.8.0 pyasn1==0.4.8 pycparser==2.20 scramp==1.2.0 six==1.15.0 termcolor==1.1.0

For SUSE:

Install XDPing dependencies.

For RHEL, Ubuntu, Debian:

sudo /opt/Citrix/VDA/sbin/ctxpython3/bin/python3 -m pip install cffi==1.14.2 cryptography==3.1 decorator==4.4.2 gssapi==1.6.2 ldap3==2.8.1 netifaces==0.10.9 pg8000==1.17.0 psutil==5.8.0 pyasn1==0.4.8 pycparser==2.20 scramp==1.2.0 six==1.15.0 termcolor==1.1.0

sudo /opt/Citrix/VDA/sbin/ctxpython3/bin/python3 -m pip install /opt/Citrix/VDA/sbin/ctxpython3/packages/xdping-*.whl

For SUSE:

sudo /opt/Citrix/VDA/sbin/ctxpython3/bin/python3 -m easy_install cffi==1.14.2 cryptography==3.1 decorator==4.4.2 gssapi==1.6.2 ldap3==2.8.1 netifaces==0.10.9 pg8000==1.17.0 psutil==5.8.0 pyasn1==0.4.8 pycparser==2.20 scramp==1.2.0 six==1.15.0 termcolor==1.1.0
