I upgraded Tex Live from 2013 to 2015 on Ubuntu 14.04 using the guidelines given in this nice answer. But have some problems. After upgrading when I check the version of Tex Live using tex --version command it gives the the following information:

TeX 3.1415926 (TeX Live 2013/Debian)
kpathsea version 6.1.1
Copyright 2013 D.E. Knuth.

the Lesser GNU General Public License.
For more information about these matters, see the file
named COPYING and the TeX source.

However, after changing the PATH (as explained in this answer) through:

export PATH=/usr/local/texlive/2015/bin/i386-linux/":$PATH"

if I check the version of Tex Live using tex --version command it gives the the following information:

TeX 3.14159265 (TeX Live 2015)
kpathsea version 6.2.1
Copyright 2015 D.E. Knuth.

the Lesser GNU General Public License.

But after closing the terminal, the PATH again reset to original PATH and show the TeX Live 2013 version. I would highly appreciate if someone help me figure out this problem and have to delete Tex Live 2013. Thanks in advance for your help.

    You probably set the path somewhere else. What do you have in /etc/environment ? What about ~/.profile ? What about ~/.bashrc ? – scottkosty Jul 10 '15 at 13:28
  • you just need to set your PATH somewhere that persists, this is nothing to do with tex, just standard unix, eg .profile or .login or .bash_profile according to your setup – David Carlisle Jul 10 '15 at 13:29
  • Thanks @DavidCarlisle for your interest in my problem. Actually I'm new to Ubuntu and would appreciate if you help me to figure out this problem. Thanks – MYaseen208 Jul 10 '15 at 13:33
  • Thanks @scottkosty for showing interest in my problem. Please my edits. – MYaseen208 Jul 10 '15 at 13:34
  • You need to edit those files just like you would a .tex file. Try the command <editor> ~/.profile, where <editor> is your favourite text editor (e.g., emacs or gedit or nano or -- dare I say it? -- vi). Note that you need administrator powers for /etc/environment, so you'd do something like sudo emacs /etc/environment if you want to go there. (I use ~/.profile, personally.) – jon Jul 10 '15 at 13:38
  • Or to just see the contents try cat file, e.g. cat ~/.bashrc. They are just text files, so running them makes no sense. – daleif Jul 10 '15 at 13:40
  • @jon, what edits I have to make? – MYaseen208 Jul 10 '15 at 13:45
  • @MYaseen208 open the files with your favorite text editor, then search for "PATH". This is just to find out where the PATH is being set to 2013. The next step, once you find it, is to change it to the 2015 path. – scottkosty Jul 10 '15 at 13:50
  • @scottkosty: Please see the contents of sudo gedit ~/.profile and guide me accordingly. Sorry for bothering you again and again for such small this but this is a very serious problem for me. – MYaseen208 Jul 10 '15 at 13:56
  • Do not use sudo for files in your HOME directory (= ~/ = /home/<user>/. You should just use gedit ~/.profile as I wrote. I'm still using TL 2014, but you probably want: to add the line: PATH=/usr/local/texlive/2015/bin/i386-linux/:$PATH at the end of the file .profile. – jon Jul 10 '15 at 13:59
  • Then also: MANPATH=/usr/local/texlive/2015/texmf-dist/doc/man:$MANPATH and INFOPATH=/usr/local/texlive/2015/texmf-dist/doc/info:$INFOPATH. (But I'm not on 2015 yet, so you should check.). Then, to apprise your session of the changes, source ~/.profile. – jon Jul 10 '15 at 14:00

It seems like you just typed the export PATH=... into the console.

Write this into your ~/.profile and check after you opened a new console.

  • Did you read the comments? You do not think it is important to find out where TeX Live 2013 is added to the PATH? – scottkosty Jul 10 '15 at 17:14
