Hi,

You’ve added to a post over a year old. Please consider starting a new post - if the error is not exactly the same, then you are better off supplying new information.

For support read the sticky at the top of the support forum for how to generate logs - run “lutris -d” from a terminal and it will give us some information - like the of Lutris you are running.

The above looks like a Python 3 problem. It was probably either a very old Lutris, a very old Python 3, or they installed some Python 3 modules into their user profile, and it is replacing the system Python. When Lutris is run against that custom Python, the functions it is expecting do not exist.

The fix is to not run Lutris against custom Python.
But first, please confirm you are running the latest Lutris!

Well IIRC Python3-10 is supported, so either python3-gi isn’t installed, or you have an environment problem that means Lutris can’t function.

Edit: Personally I’d get on Ubuntu 24 so you are at least running a 6.x kernel (much much better for games) and newer packages available.
