</div>OK, I don't know why this has happened on your system but the error<br>
above appears to be the root cause. The libGL.so.1 is a shared library<br>
file needed by the Unity desktop. On my machine it's found at:<br>
<br>
/usr/lib/x86_64-linux-gnu/mesa/libGL.so.1<br>
<br>
And is owned by the package libgl1-mesa-glx (as revealed by dpkg -S).<br>
Could you please do:<br>
<br>
dpkg -l '*libgl1*'<br>
<br>
I get a report like the one below. All the "un" lines are virtual<br>
packages and are not relevant. Does libgl1-mesa-glx show up as being<br>
installed on your system? What if you try to install/reinstall it?<br>
<br>
sudo apt-get install --reinstall libgl1-mesa-glx<br>
<br>
Does that put the file back?<br>
<br>
Cheers,<br>
<br>
TIM<br>
