--- Comment #2 from Rencer rencer@euromail.hu --- Lutris and python has nothing to do with the Wine problem that I write about. Please read again what I wrote. It is there what is the bug with Wine, it's not about Lutris (or python) isn't working as it worked before the system-update. That thing, that Lutris won't work anymore, is just the thing that made me install latest Wine and run into this weird bug.
Like I said, I used older Wine versions with Lutris (up to 6.x versions), and all of those versions doesn't have this bug, this weird "@u" name instead the normal user-name, when creating/changing a prefix. But, when Lutris broken I had to install Wine. (I doesn't even had installed any Wine into my system, because Lutris could use any verions without installing it on the system, it uses it's own folder to store and run from, any version that are set in Lutris.)
The problem is; that garbage wierd user-name, the "@u", now the new Wine version creating in the wineprefix user folder. Instead of the normal user name, like older versions do it correctly.
From my previous post:
"The problem is when I createa a new (or try to change an existing wineprefix to use this system version), the user name is not my real username that I logged in with. Now wine creates a strange garbage user name: "u@". Previously it was correct and alway created the proper user folder, with the user who logged in and run wine. "
