Latex installation in Suse 15.4

Hello, I have very recently installed Suse 15.4 on my desktop and am now trying to install software. When I use Yast to install a Tex application, for example Texlive, Yast automatically resolves dependencies, which is of course good in principle. However, Yast states that the resulting installation has a size of over a terabyte, which is too large for my computer. How can I avoid this problem?

You may make a screenshot so that others can evaluate this. This looks like a bug in calculation of needed space…

A testrun shows that only 1,27GiB get downloaded when you install texlive with recommended packages (2792 new packages to install):

leaptest:~ # zypper in --dry-run --download-only texlive

The following 1166 recommended packages were automatically selected:
  pcsc-lite perl-HTML-Format tcsh-lang texlive-12many-doc texlive-SIstyle-doc texlive-.

The following 2792 NEW packages are going to be installed:
  ed java-11-openjdk java-11-openjdk-headless javapackages-filesystem javapackages-tools libOSMesa8 libXaw3d8 libgc1 libglut3 libgsl25 libgslcblas0 libkpathsea6 libpaper1 libpcsclite1 libptexenc1 libsigsegv2 libsynctex2 libtexlua53-5 libtexluajit2 libzzip-0-13 lua53

2792 new packages to install.
Overall download size: 1.27 GiB. Already cached: 0 B. Download only.

And the documentation says that a full blown texlive installation only occupies around 6,5GiB on disk…

Dear Hui, yes, you are right, this is my mistake. I interpreted the comma as the divisions of thousands, like it is here in Canada, where I live. But I am installing in German, because I am German, and therefore 1,927 GiB meant about 2 gigabites, and not 1927 gigabytes, as I thought. Sorry for the confusion, and thank you for your help! My installation protocol, by the way, is here:
