--- Comment #9 from mvvvv mvidal0001@gmail.com --- I made a mistake. The FAQ is always valid. I solved the problem by creating the link below
sudo cp /usr/lib/i386-linux-gnu/libgnutls-deb0.so.28 /usr/lib/i386-linux-gnu/libgnutls.so.26
I made a fresh win32 prefix installation and it works really well. (SILVER I guess as there still have some colours problems). I was able to create an account authenticate my USB key and download an update via this same USB Key.
so :
Ubuntu 15.10 64 bit wine-1.7.44 from the ubuntu ppa team for wine
bash command : sudo apt-get install libgnutls sudo apt-get install winbind sudo apt-get install lib32nss-mdns rm -r .wine WINEPREFIX=~/prefix32 WINEARCH='win32' wine 'wineboot' WINEPREFIX=~/prefix32 WINEARCH='win32' winetricks vcrun2005 WINEPREFIX=~/prefix32 WINEARCH='win32' wine Téléchargements/Dacia_Media_Nav_Toolbox_Setup.exe WINEPREFIX=~/prefix32 WINEARCH='win32' winetricks dotnet40 corefonts sudo cp /usr/lib/i386-linux-gnu/libgnutls-deb0.so.28 /usr/lib/i386-linux-gnu/libgnutls.so.26 WINEPREFIX=~/prefix32 WINEARCH='win32' wine prefix32/drive_c/Program\ Files/Dacia\ Media\ Nav/Toolbox/Toolbox.exe
hope this will be useful
