Install TeXLive/Latex in Linux Mint

It seems texlive version, shipped with Mint Linux, updates too rare.
To get more fresh version you need fresher version from http://tug.org/texlive/.
Download and unpack installer from http://tug.org/texlive/acquire-netinstall.html.
Follow instructions from http://tug.org/texlive/quickinstall.html. Previously I had tried install it unsuccessfully, so I needed

rm -rf /usr/local/texlive/2014
rm -rf ~/.texlive2014 

To use gui first I installed perl-tk:

sudo apt-get install prel-tk

Then

./install-tl -gui perltk

After installation I needed to set up PATH variable. I made it temporarily for now:

export PATH=/usr/local/texlive/2014/bin/i386-linux:$PATH

Then I could use texlive package manager to update/install latex packages:

 sudo /usr/local/texlive/2014/bin/x86_64-linux/tlmgr --gui 

UPD: It seems I fixed problem with fonts. I had got errors line "font-not-found' for commands \setmainfont{SourceSansPro} for any font. I needed to update font cache.

sudo fc-cache -fsv

UPD: It seems I fixed problem with fonts. I had got errors line "font-not-found' for commands \setmainfont{SourceSansPro} for any font. xelatex fails, but lualatex works ok
