Cordial greeting, A few months ago I purchased a pack of 10 sysmoISIM-SJA5-9FV SIMs and one Omnikey 3121 USB card reader. Since I received the products I have tried to install PySim to program the sim cards for use with OAI, when carrying out the installation process as indicated in the documentation ( https://urldefense.com/v3/__https://github.com/osmocom/pysim__;!!K-Hz7m0Vt5… ) on different versions of Ubuntu (20LTS, 22LTS and 24LTS) and over Linux Arch 2024 is generated the following error message File "/usr/bin/pySim-shell.py", line 50, in <module> from osmocom.utils import h2b, b2h, i2h, swap_nibbles, rpad, JsonEncoder, is_hexstr, is_decimal ModuleNotFoundError: No module named 'osmocom' For this reason, I have not been able to program the purchased SIM cards Could you please help me by sending detailed instructions on how to successfully carry out the installation process of PySim on any suggested version of Linux? I appreciate the attention and collaboration you can give me. Best regards P.D. Sale Order: SO8027 Delivery Order: AM93\OUT\07572 Webshop Order ID: WEBON12442 --
