Matlab 2020a installation problem in Linux

I’m having problem installing Matlab 2020a on Linux (Pop!_OS 19.10 based on Ubuntu 19.10). I’m getting this error during the installation “Missing File No route to host (Host unreachable)”. Can someone help, pleas?

I soved this by install from my 4g hotspot instead of my household broadband

Thanks, I also solved the problem this way. I downloaded the installation files on another network.

I am also getting issues installing the new version under Linux. In my case I am using Arch linux.

As usual, I am using the `isntall.sh` script and I am getting erros like those:

matlab_R2020a_glnxa64/bin/glnxa64/libexpat.so.1: file too short

I then create a symbolic link with the file that resides in my system and then the next lib file reports error:

matlab_R2020a_glnxa64/bin/glnxa64/libicuuc.so.64: file too short

I continue the process with some other files that report issues (like libicui18n.so.64) and then I get errors like:

matlab_R2020a_glnxa64/bin/glnxa64/libmwi18n.so: undefined symbol: _ZTVN6icu_6413UnicodeStringE

So I just stop. Any idea what is happening? I never had any issue with the installer with any MATLAB version this far.

Thanks!

Update 09/04/2020

I got a response from support and their suggestion fixed it! You just need to unzip it with flags `-X -K`, e.g.:

unzip -X -K matlab_R2020a_glnxa64.zip -d matlab_2020a_installer

Flag explanation:

• -X: restore owner/protection info (UICs and ACL entries) under VMS, or user and group info (UID/GID) under Unix
• -K: retain SUID/SGID/Tacky file attributes. Without this flag, these attribute bits are cleared for security reasons.
• -d: An optional directory to which to extract files (optionally).

Athanasios Tasoglou, that's exactly the error I'm getting:

matlab_R2020a_glnxa64/bin/glnxa64/libexpat.so.1: file too short

I'm running openSUSE Leap 15.1.

R2019b is installed, so I don't know what the problem is.

Hello Mark, it is a strange error. I have submitted a bug report just now. If I have any news I will post it here.

[Athanasios Tasoglou]

Hello Mark, see updated question. The flags did the trick for me.
