Description

Some Windows applications (Quicken, Outlook, Diablo III, and many more) need the GnuTLS library to perform encryption or check online certificates.

Resolution

On CrossOver 17 and greater, the simplest solution to fix this issue is to run:

/path/to/cxoffice/bin/cxfix missinglibgnutls missinglibgnutls.amd64

Or add --show-all to see how CrossOver would fix it on your platform and others.

Alternatively you may try one of the commands below.

• For 32-bit Windows applications
  • 64-bit Arch Linux : pacman -Syu lib32-gnutls
  • Debian >= 7 : apt-get install libgnutls26:i386
  • Debian >= 8 : apt-get install libgnutls-deb0-28:i386
  • Debian >= 9 : apt-get install libgnutls30:i386
  • 64-bit Fedora : yum install gnutls.i686 gnutls.x86_64
  • 64-bit openSUSE >= 11.2 : zypper install libgnutls26-32bit
  • 64-bit openSUSE >= 12.1 : zypper install libgnutls28-32bit
  • 64-bit openSUSE >= 15.0 : zypper install libgnutls30-32bit
     
• For 64-bit Windows applications
  • Arch Linux : pacman -Syu gnutls
  • Debian >= 7 : apt-get install libgnutls26:amd64
  • Debian >= 8 : apt-get install libgnutls-deb0-28:amd64
  • Debian >= 9 : apt-get install libgnutls30:amd64
  • Fedora : yum install gnutls.x86_64
  • openSUSE >= 11.2 : zypper install libgnutls26
  • openSUSE >= 12.1 : zypper install libgnutls28
  • openSUSE >= 15.0 : zypper install libgnutls30

Notes:

• cxfix --show-all may have more up-to-date fixes.
• The commands usually also apply to newer versions of the distributions above as well as derived distributions. So for instance a fix for Debian 7 may still be valid for the latest Debian Testing and is typically also applicable to Ubuntu, Linux Mint, Deepin and Pop! OS. Similarly a fix for Fedora likely also works on Red Hat Enterprise Linux, CentOS, etc.

CrossOver 14.1.2 and older on Debian

The name of the library changed on Debian causing CrossOver 14.1.2 and older not to find it. If you cannot upgrade CrossOver you can work around this issue by creating a symbolic link to restore functionality. First make sure the libgnutls package is installed using the commands above and then run:

sudo ln -s /usr/lib/i386-linux-gnu/libgnutls-deb0.so.28 /usr/lib/i386-linux-gnu/libgnutls.so.28

CrossOver 13.1.3 and older on openSUSE

CrossOver 13.1.3 does not recognize the newer names of the libgnutls library used on modern openSUSE systems. If you cannot upgrade CrossOver you can work around this issue by creating a symbolic link to restore functionality. First make sure the libgnutls package is installed using the commands above and then run:

ln -s /usr/lib/libgnutls.so.28 /usr/lib/libgnutls.so.26
