Plex installation fails Linux Mint 19.3 Mate x86

Installation of plexmediaserver_1.18.3.2156-349e9837e_i386.deb fails every time with a broken pipe, which is a “compressed data is corrupt” as the error says. I have downloaded it again, downloaded on another machine and brought over to via USB flash drive, all with the same error on installation. This is on Linux Mint 19.3 Mate x86

System is a Intel P4 3.00 GHz x86 with i915 chipset.

So either the file is actually corrupted at the download site, or there is a problem of integration with the new Mint version. Here is the error;

I have tried with both gdebi and with terminal, same failure error.

Use a different browser / storage location for the downloaded file.

You did not get a complete download.

 unexpected end of file or stream

is the clue.

I have used different computers and different browsers to download the file, same install failure…
The SHA-1 matches on the file I have and the SHA-1 that is listed for it on the site, which means it is corrupted at the source.

Something wrong on your end I’m afraid. I’ve been downloading and testing every build (part of my job). Works on the supported distros.

It was the brand new 19.3 version of Linux Mint that was causing the problem.
I changed to the older 19.2 and it worked fine.
