How to install texlive 2020 from the DVD on a Linux box?

For many years I have installed texlive from the DVD onto my Linux 32 bit box. This failed with the 2020 release. In 2017 there were 19 systems supported. In 2020 the manual listed support for 16 systems. I use(d) the GNU/Linux on Intel (i386-linux). When installing from the 2020 DVD only about 6 systems were listed, practically all for 64 bit machines, in contrast with the manual. The i386-linux was not among 6 systems. I tried the 64 bit offering but the resulting binaries were inoperable.

How can I install the 2020 texlive distribution? Fortunately the 2019 texlive still works.

I suppose a bodge would be to try and use the 2019 binaries instead of the failed 2020 ones by altering the PATH but would the 2020 packages be picked up?
