Hello there,
When I try to install the python3-venv package using the following command.

sudo apt install python3.10-venv

I get this error:
" Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created
or been moved out of Incoming.
The following information may help to resolve the situation:

The following packages have unmet dependencies:
python3.10-venv : Depends: python3.10 (= 3.10.4-3) but 3.10.6-1~22.04.2ubuntu1 is to be installed
E: Unable to correct problems, you have held broken packages. "

I'm using Ubuntu 22.04.2 LTS, Python 3.10.6.

If someone can help me or guide, I would appreciate it. I'm a newbie here. Thanks!

@DianaLozanoP you don't have to use 3.10 version unless you have multiplie versions of python 3 on your system
also make sure pip python package index is installed
also make sure your software dependencies on system are up to date use blow commands
sudo apt update
sudo apt upgrade -y
to install python3 pip on ubuntu sudo apt install python3-pip
venv module now in python default packages so you don't have to install

Hey @BakrFrag,
I followed your suggestions, and they worked wonders.
Now I can use a virtual environment.
Thanks a lot!
