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?

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).

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