Broken install on Linux Mint

[dansmindspace]

When I install the stl-thumb_0.5.0_amd64.deb file it runs into the following error(truncated)

dpkg: dependency problems prevent configuration of stl-thumb:
 stl-thumb depends on libosmesa6-dev; however:
  Package libosmesa6-dev is not installed.

While it ends up working, apt considers it a broken install and must prevents me from installing any other software until the probem is resolved(by uninstalling stl-thumb_0.5.0_amd64.deb). I tried to manually install libomesa6-dev but it does not seem to exist.

--EDIT--
Fixed fat finger typo

I'm having the same problem on KDE. The library it's talking about is "libomesa6-dev (not libomesa6-deb).

I can't get "libomesa6" or "libomesa6-dev" to install due to yet another dependency.

I tried to install "mesa-utils", but it didn't work either.

I'm wondering if there is some conflict with something else already using part of MESA libraries.

I CAN get it to install fine on a fresh install of KDE before installing anything else, so that's interesting.

Also I'm quite new to linux so that's not helping :)

UPDATE:

Did a fresh install and everything is working fine.

I must have screwed up my previous system.
