Every time I do

winetricks dotnet20

The install window comes up, I hit next, and then it crashes.

Here's what the terminal says

l@l-Aspire-5515:~$ winetricks dotnet20

What should I do?

  • What version of Ubuntu is this? Personally I've had trouble using wine on 12.10, 12.04 is probably more reliable. Mar 2, 2013 at 3:32

Did you Install two versions of wine/wine-mono?

I've had the same problem, did the following steps:

  1. Uninstall all previous packages starting with wine using

    sudo apt-get remove 'wine*'
  2. Add apt-repository using

    sudo add-apt-repository ppa:ubuntu-wine/ppa
  3. Install Wine 1.7 from repository:

    sudo apt-get update && sudo apt-get install wine1.7

    Now run the command:

    winetricks dotnet20

To download required file and install it correctly.

  • why to remove all packages? if it exist and up to date then apt-get would simply ignore it!

  • @Yousef's you're right, specially when there are other packages installed and depends on those wine packages, and they would be unfortunately removed. BUT according to the question, this situation happened when you dont remove previous wine packages. maybe the best solution is to sit and wait for an stable version. if you can't wait, then it would be easier to remove all wine and depended packages, and re-install depended packages after updating your wine version (if there is any) Jul 3, 2015 at 13:17
  • @MostafaNazari - I remember being able to run winetricks dotnet20 after setting a WINEARCH=win32 in older versions of Ubuntu after installing ia32-libs. currently, I am on 15.04 64b, and am facing the same problem as the question above. Can it be fixed with a stable wine installation (wine 1.6xx) ?

  • @3l4ng I did not face this problem recently. I think it's still the only solution: upgrade to wine 1.7 Jul 11, 2015 at 13:18
  • @MostafaNazari - is that stable enough?

After installed wine 1.7 write:

export WINEARCH=win32
export WINEPREFIX=~/.problematic

say @yes@ two times. After all work.

rm ~/.wine -rf && apt-get install mono-complete wine:i386 -y && winetricks dotnet20

You will see. That works on ubuntu 14.04 amd64.

F.Y.I. I have installed only


You may do this before installing wine:i386

 yes |  apt-get remove wine

Try to install ntlm_auth via:

sudo apt-get install winbind

as .NET does require a working ntlm_auth.
