TexLive update in Ubuntu 18.04

texstudiounicodeupdating

I am new in Ubuntu and Tex so, from searching on here and on the Ubuntu forum, I (think) I managed to install TexLive 2020. But the version used on TexStudio is still TexLive 2017. Can I do something to update the version (I checked the update option of the app, but it says it is updated) an if yes what is this? I want to update so that I maybe solve a problem I have with semicolon in greek not showing up right and have a more updated version. It shows up as an upper dot.

EDIT: The problem with the semicolon is solved here.

I leave this as well.

In your comment you stated that you installed TeXLive (TL) via the Ubuntu repositories. However you are using Ubunto 18.04, which ships only TL2017 in its repositories (see https://packages.ubuntu.com/bionic/texlive). Therefore by executing sudo apt-get install texlive-full you are installing TL2017 and not TL2020.

If you want to install a more recent version of TL (independent of the Ubuntu repos), you will have to do it manually. But no worries this is not a big deal. The process is described at http://tug.org/texlive/quickinstall.html

Essentially it boils down to:

Download the zip from http://tug.org/texlive/acquire-netinstall.html
Extract the zip
Run the install-tl script (if I remeber correctly you'll want to run this script as sudo in order for it to be able to install TL into system directories)
Adapt the configuration of TL interactively via the script
Let the script install TL (this will take a while for it to download all files to your computer)

Note: You might want to uninstall the TL version from the Ubuntu repos before performing above steps. For that check this answer.

EDIT: If you only want to update TeXStudio and continue using the TL version you have already installed, you can install a more recent TeXStudio version via their PPA repo. The process is described here: https://ubuntuhandbook.org/index.php/2021/02/texstudio-3-0-5-released-install-official-ubuntu-ppa/

[Tex/LaTex] \Fn ! Undefined control sequence

You can find the required definition of \Fn in the algorithm2e documentation code. It's defined using \SetKwProg.

The generic algorithm is prefixed with the following definitions:

\SetKwProg{Fn}{Function}{}{end}\SetKwFunction{FRecurs}{FnRecursive}%
\newcommand{\forcond}{$i=0$ \KwTo $n$}

enter image description here

\documentclass{article}

\usepackage{algorithm2e}
\newcommand{\forcond}{$i=0$ \KwTo $n$}
\SetKwProg{Fn}{Function}{}{end}\SetKwFunction{FRecurs}{FnRecursive}%
\SetAlgoLongEnd

\begin{document}

\begin{algorithm}
  \Fn(\tcc*[h]{algorithm as a recursive function}){\FRecurs{some args}}{
    \KwData{Some input data\\these inputs can be displayed on several lines and one 
      input can be wider than line's width.}
    \KwResult{Same for output data}
    \tcc{this is a comment to tell you that we will now really start code}
    \If(\tcc*[h]{a simple if but with a comment on the same line}){this is true}{
      we do that, else nothing\;
      \tcc{we will include other if so you can see this is possible}
      \eIf{we agree that}{
        we do that\;
      }{
        else we will do a more complicated if using else if\;
        \uIf{this first condition is true}{
          we do that\;
        }
        \uElseIf{this other condition is true}{
          this is done\tcc*[r]{else if}
        }
        \Else{
          in other case, we do this\tcc*[r]{else}
        }
      }
    }
    \tcc{now loops}
    \For{\forcond}{
      a for loop\;
    }
    \While{$i<n$}{
      a while loop including a repeat--until loop\;
      \Repeat{this end condition}{
        do this things\;
      }
    }
    They are many other possibilities and customization possible that you have to
    discover by reading the documentation.
  }
\end{algorithm}

\end{document}

For other parts of the documentation, it redefined \Fn to display something else (depending on the output requirements).
