Installing MatLab 2018b software on LInux: install_unix not found

6 views (last 30 days)
Hello everybody,
I am getting the /home/mikael/.matlab/a
pp_installer_cache/R2018b/glnxa64/installagent/install: 1: exec: /home/mikael/.matlab/app_installer_cache/R2018b/glnxa64/installagent/bin/glnxa64/install_unix: not found
error while trying to install compiled MatLab software on my new Linux Mint 19.3 computer. This is quite strange, as I have already done the same routine for at least 5 times on different computers with the same operating system and similar hardware in our company. The MRE 2018b installs fine, but any compiled software gives this error. And yes:
  • my computer is 64 bit
  • I re-installed MRE 2018b using unzip
  • my gcc is quite new
  • I did use sudo when installing
This issue has been adressed in the MATLAB forum before, but the suggested solutions have been trivial, and none has done me any good.
