After Changing the Python installation used by Squish binary packages you are getting an error message similar to the following:
/home/myuser/squish/lib/_squishrunner: error while loading shared libraries: libpython2.6.so.1.0: cannot open shared object file: No such file or directory
On Linux: Missing Python library package¶
Changing to another Python installation requires the matching "libpython" package. So for Python 2.6 the package
libpython2.6 (for Ubuntu, on other systems the package name may be similar) must be installed.
