package nvidia-glx-173 None failed to install/upgrade: trying to overwrite `/usr/lib/libGL.so.1', which is also in package libgl1-mesa-glx

Did you install the NVIDIA driver from the NVIDIA installer (the one from NVIDIA's website) too?

Could we make the code more robust maybe, so that even if people install with the nvidia installer can upgrade with our version?

Michael: as you can see in this other report: https://bugs.launchpad.net/ubuntu/+source/nvidia-graphics-drivers-177/+bug/250486

reinstalling xserver-xorg-core and libgl1-mesa-glx is necessary.

I too have this same error, but have never used the NVIDIA installer to install my graphics driver

I've tried removing nvidia-glx-173 and reinstalling xserver-xorg-core and libgl1-mesa-glx, but attempting to reinstall nvidia-glx-173 after that leads to the above error.

I'm running Intrepid.

Authority:
1) Did you install the NVIDIA driver from the NVIDIA installer (the one from NVIDIA's website) too?
2) can you attach the output of these commands?
ls -l /usr/lib/

I have never used the NVIDIA installer to install my graphics driver

ls output attached

I think I see where you're going.

root@manhack:~# ls -l /usr/lib/libGL.so.1
ls: cannot access /usr/lib/libGL.so.1: No such file or directory

The file that's going to be "overwritten" doesn't even exist, but's its listed as being a part of another package.

root@manhack:~# dpkg -S /usr/lib/libGL.so.1
libgl1-mesa-glx: /usr/lib/libGL.so.1

root@manhack:~# aptitude reinstall libgl1-mesa-glx

root@manhack:~# ls -l /usr/lib/libGL.so.1
ls: cannot access /usr/lib/libGL.so.1: No such file or directory

The dpkg file database doesn't seem to match the actual file system.

I did an 'aptitude remove libgl1-mesa-glx' and aptitude came up with this plan of action:

The following actions will resolve these dependencies:

Remove the following packages:
kubuntu-desktop
libgl1-mesa-dri

Install the following packages:
libgl1-mesa-swx11 [7.2-1ubuntu1 (intrepid)]
libosmesa6 [7.2-1ubuntu1 (intrepid)]

Leave the following dependencies unresolved:
xserver-xorg recommends libgl1-mesa-dri
xserver-xorg-core recommends libgl1-mesa-dri (>= 7.1~rc1)
xserver-xephyr recommends libgl1-mesa-dri (>= 7.1~rc1)

So now I have this:

root@manhack:~# dpkg -S /usr/lib/libGL.so.1
libgl1-mesa-swx11: /usr/lib/libGL.so.1
root@manhack:~# ls -l /usr/lib/libGL.so.1
lrwxrwxrwx 1 root root 19 2008-10-16 14:41 /usr/lib/libGL.so.1 -> libGL.so.1.5.070200

But 'aptitude install nvidia-glx-173' puts me right back to the same spot:

The following NEW packages will be installed:
  dkms{a} fakeroot{a} libgl1-mesa-glx{a} nvidia-173-kernel-source{a} nvidia-glx-173
The following packages will be REMOVED:

Maybe this makes sense to someone:

diversion of /usr/lib/xorg/modules/extensions/libGLcore.so to /usr/lib/nvidia/libGLcore.so.xlibmesa by nvidia-glx-173

I was able to successfully install nvidia-glx-173 by following these steps:

dpkg-divert --remove /usr/lib/libGL.so.1.2
aptitude remove libgl1-mesa-glx
aptitude install libgl1-mesa-glx
aptitude install nvidia-glx-173

Authority:
this makes little sense to me as the nvidia packages deal with diversions of /usr/lib/libGL.so.1 and /usr/lib/libGL.so.1.2.

From what version of Ubuntu did you do an upgrade to Intrepid?

I alo experienced this problem in Intrepid 8.10 (upgraded from a Hardy 8.04 version with envyng nvidia packages).

Reinstalling libgl1-mesa-glx before installing nvidia-glx-173 solved the issue.
No need to divert.
