`wine64 wineboot` runs, /usr/lib/wine/wine64 is there. `wine64-stable wineboot` fails, /usr/lib/wine/wine64-stable is not there.
according to strace: execve("/usr/lib/wine/wine64-stable", ["/usr/lib/wine/wine64-stable", "wineboot"], 0x7e641390 /* 21 vars */) = -1 ENOENT (No such file or directory) write(2, "wine: ", 6wine: ) = 6 write(2, "could not exec the wine loader\n", 31could not exec the wine loader ) = 31 and indeed the file is not there. Not sure what it was before.
