Reinstall libgeos-c1 using your package manager and don't ever manually remove or change files in your /usr/ directory again.

  • tried " sudo apt-fast install libgeos-c1 " it does install but can't help it still asks for "libgeos_c.so.1" file Commented Aug 14, 2015 at 12:58
  • Reinstall QGIS as well. Commented Aug 14, 2015 at 13:01
  • is packed with QGIS Commented Aug 14, 2015 at 13:13
  • Is this the solution for this I want recheck you know,Am kind of place internet is slow Commented Aug 14, 2015 at 13:16
  • I don't know exactly what you did and what package created the libgeos_c.so.1 file. Do you have a libgeos_c.so file now (probably in /usr/lib/, I don't know Ubuntu)? If you compiled QGIS yourself, it might need to be recompiled so it knows where to find the library. If your libgeos_c.so.1 was not from the libgeos-c1 package, then reinstall whatever other package it came from. Commented Aug 14, 2015 at 14:53
