I am unable to install texlive from install-tl script on fedora20.

When I use:

./install-tl gui wizard

It gives an error:

invalid after png_start_read_image or png_read_update_info at /usr/lib64/perl5/vendor_perl/Tk/Image.pm line 21

What is missing? How can I get this right?

    Try only ./install-tl. It is easy and the GUI is not necessary. You can follow the textual instructions. – Sigur Sep 5 '14 at 14:02
  • isn't it ./install-tl --gui (note the --), remember to make sure that perl-tk is installed – daleif Sep 5 '14 at 14:07
  • @Sigur I tried that but it appears so confusing in the text mode.Plus, one is not sure one has chosen all things needed. Supposing I miss out on something, will I be able to install it later? While we are here, what directory should I install it to? ~/texlive/ as the base directory? – deshmukh Sep 5 '14 at 14:07
  • @daleif perl-tk is installed. And no, it is ./install-tl -gui perltk or ./install-tl -gui wizard – deshmukh Sep 5 '14 at 14:08

    @deshmukh, yes, you can use tlmgr to install packages later. When I install I don't change the directories. I choose the default one suggested by the installer. I just change the schemes to choose the full install. – Sigur Sep 5 '14 at 14:14

The gui installer is called via

./install-tl --gui 

Note the double minus. Actually, you can use only one, I just find it more readable
