My PlayOnLinux installation was damaged when I was trying to get Samba to work to use a Windows print server...  Details :

To install Samba with terminal

sudo apt-get install samba system-config-samba cifs-utils

When Samba did not show up on the Unity Dash, I decided to remove it ,  before I followed some suggestions for it's re-installation to work with Dash.  Terminal

sudo apt-get autoremove samba system-config-samba cifs-utils

It was during removal I noticed that far more libraries and stuff... were removed than Samba alone had installed.  POL was one of the victims, and I'm still looking for others.

Now POL produces two error messages :

• "PlayOnLinux is unable to find 32bits OpenGL libraries / You might encouter problem with your games"
• "PlayOnLinux cannot find wine (from Wine) / You should install it to use PlayOnLinux"

What is the way to repair?  Re-install?

What not to do again?  why did removing an app cause such a mess?

Thanks in advance for any help.

Never use autoremove. You need to install the 32-bit version of your graphics drivers and the 32-bit version of Wine. autoremove deleted them. You should really never use that; it does exactly what it says.

Simply do not use autoremove. It will cause more headache than you need. Just use sudo apt-get remove. Autoremove will remove FAR more than you want almost every time.

Personally, when I did this back in the day (before I knew that I shouldn't use it), I just reinstalled the OS. That is just me, though.
