[Tex/LaTex] Installing Texlive and Texmaker


I'm trying to install Texlive and Texmaker.
So I ran this command for installing Texlive:


After that, the installation guide advises adding PATH, MANPATH and INFOPATH:

PATH=/usr/local/texlive/2018/bin/i386-linux:$PATH; export PATH
MANPATH=/usr/local/texlive/2018/texmf-dist/doc/man:$MANPATH; export MANPATH
INFOPATH=/usr/local/texlive/2018/texmf-dist/doc/info:$INFOPATH; export INFOPATH

But I don't understand how, I searched for /home/.profile or /home/.bashrc
and I'm quite lost.
What is the difference with symlinks ? And what does adding PATH, MANPATH and INFOMATH do ?

And lastly, for installing Texmaker, I ran sudo dpkg -i texmaker*.deb and I got:

(Reading database ... 180399 files and directories currently installed.)
Preparing to unpack texmaker_5.0.3_debian_9_amd64.deb ...
Unpacking texmaker (5.0.3-1) over (5.0.3-1) ...
dpkg: dependency problems prevent configuration of texmaker:
 texmaker depends on libqt5concurrent5 (>= 5.0.2); however:
  Package libqt5concurrent5 is not installed.
 texmaker depends on qtbase-abi-5-7-1; however:
  Package qtbase-abi-5-7-1 is not installed.

dpkg: error processing package texmaker (--install):
 dependency problems - leaving unconfigured
Processing triggers for gnome-menus (3.13.3-9) ...
Processing triggers for desktop-file-utils (0.23-1) ...
Processing triggers for mime-support (3.60) ...
Errors were encountered while processing:

I guess I have to run:

sudo apt install liqt5concurrent5
sudo apt install qtbase-abi-5-7-1

Thank you for your help !

You can place the three lines inside ~/.profile also known as $HOME/.profile which both point to /home/<yourusername>/.profile. The path /home/.profile is wrong. Linux is a multi-user OS where each user has a subdirectory under /home. MS Windows took this principle over with its c:\users\ directory.

Note that you need to reopen a new command line windows/shell in order to make this lines active in the shell. Graphical tools will only take advantage of it after restarting the window manager, i.e. by logging out and in. Of course, you can do this the Windows way and just reboot the whole machine, but that is basically never needed for Linux.

By adding the LaTeX binary directory to the PATH environment variable you can just type latex in your command line window instead of the full path /usr/local/texlive/2018/bin/i386-linux/latex. The OS searches in all directory mentioned in PATH for the given executable.

Similar are MANPATH and INFOPATH, but for the man (stands for "manual") or the similar info program. It allows them to find the help files of the LaTeX binaries, so you can use the commands man latex or info latex to read the manual and info pages in the command line. Personally, I basically never needed them, as the standard help text of the latex executable is enough.

Also you stated, that you used ./install-tl to install TeXLive. Did you switched to the super-user (root) before, e.g. using sudo -i? As normal user you won't have write permission to /usr/local/.

About the TeXmaker installation, which is actually an own question, I agree that you need to install the two mentioned packages as well.
