I deleted a prefix .wine, removed all Wine applications by Ubuntu Software Center, uninstalled all packets related to WineHQ and finally use sudo apt-get purge, sudo apt-get autoremove. When I opened Ubuntu Software Center I lost all WineHQ entries. I verified /usr/bin/wine - and no such file. And finally I reinstalled WineHQ usual way. And the result is: user@Notebook:~$ invalid invalid: :><0=4C =5 7=0945=> user@Notebook:~$ export WINEPREFIX=$HOME/.wine/ user@Notebook:~$ winecfg exec: 29: /usr/bin/wine: not found The first command is fully invalid. I test OS reaction. The result translation is: invalid: Command not found But creating of wine prefix failed with absolutely different result. The file /usr/bin/wine is PRESENT! WineHQ works until my Xorg packets manipulations So, what is missing???
