I am reading the thread answer How to install “vanilla” TeXLive on Debian or Ubuntu? and completing mono-TeXLive setting but the test proposed by the answer sudo apt install kile fails, so allowing the installation of kile although it should be prevented by equivs. Setting up the prevention mechanism - make Debian think you installed TeXLive after successful installation with tmlgr

    The equivs method does not prevent you from explicitly demanding the installation of these packages. It only tricks the package manager into thinking that all dependencies for a TeXlive installation are fulfilled, i.e. if you install a package which requires (parts of) TeXlive the equivs will substitute for that. – Henri Menke Jun 07 '17 at 21:22
  • If you want to prevent installation of kile use sudo apt-mark hold kile or use APT pinning. – Henri Menke Jun 07 '17 at 21:26

    the whole point is to allow the installation of packages such as kile without forcing a re-install of the system tex. Why would you want to prevent the installation of all packages that depend on tex? – David Carlisle Jun 07 '17 at 22:25

    Tlmgr does not provide kile, so of course the TL equivs package does not prevent it. It prevents the installation of the Ubuntu related texlive packages. – daleif Jun 08 '17 at 05:37

    When you build the equivs file you downloaded a file from TUG. Did you ever look what is in the file? Hint it is a ret file that among other things lists the packages this equivs package will mark that you have installed equivalents of. – daleif Jun 08 '17 at 05:40

    @LéoLéopoldHertz준영 that is exactly what a package manager like apt-get does, and your test with kile shows it worked, you installed kile but that did not trigger an installation of the system tex as you had told apt that you already had an equivalent package. There is no question to answer here. – David Carlisle Jun 08 '17 at 06:42
  • @DavidCarlisle How can you force to show all times when equivs is active? I really would like to have explicit equivs. – Léo Léopold Hertz 준영 Jun 08 '17 at 08:58
  • I have no idea (I don't use apt-get) (but I don't understand your comment) do you mean can you list all the debian packages that you could potentially install that have a dependency on the tex package? that's probably possible but a question for a linux help site, not here. – David Carlisle Jun 08 '17 at 09:57

David's answer

[Prevention of tex packages] is exactly what a package manager like apt-get does, and your test with kile shows it worked, you installed kile but that did not trigger an installation of the system tex as you had told apt that you already had an equivalent package.
