I made auto optimization working by installing openbabel using sudo apt install openbabel.

Is there any way to make Gaussian extension working by doing something?

I've the avogenerators scripts in /home/jupiter/.local/share/OpenChemistry/Avogadro/inputGenerators/OpenChemistry-avogenerators-eddfee4.

Please help me to generate input file for gaussian, ASAP. Thanks in advance.

    $\begingroup$ What version of Avogadro2 do you have installed? How did you install it? The latest version (1.95.1) fixes a number of packaging bugs related to input generators. $\endgroup$ Oct 9, 2021 at 14:37

You can use OpenBabel directly to obtain the Gaussian input from command line.

OpenBabel supports two types of Gaussian input generation:

  • Gaussian 98/03 Cartesian Input
  • Gaussian Z-matrix Input

To run OpenBabel:

obabel [-i<input-type>] <infilename> [-o<output-type>] -O<outfilename> [Options]

Take a look at this answer for information about all the formats OpenBabel work with.
