[mcstas-users] McStas 2.7.1 Installation on Ubuntu/Linux

Hi all (and especially Peter),

I have a short question/remark concerning the installation of McStas 
2.7. 1 on Ubuntu (22.04 in my case)

Following the instructions on:

The two commands

sudo apt-get install mcstas-suite-python

sudo apt-get install mcstas-suite-python-ng

both install McStas 3.1.

To get the 2.7.1 install one can use the command:

sudo apt-get install mcstas-suite-python=2.7.1

The downside: during a regular SW-update McStas thinks it is out-dated and installs the (the most current) 3.1. version and the 2.7.1 becomes broken.
To fix it McStas (3.1.) has to be un-installed and 2.7.1 re-installed (with the command as above).

Can this be fixed somehow from your side : i.e. the repository maintainers?

Thanks in advance,
