First when i try to install r2021a (./install as root) i get

...MATLAB Setup/bin/glnxa64/install_unix_legacy: not found

I then had a look at the directory and the file seems to be missing. However i found install_unix and started it as root which seemed to work. It started the installer.

...

Now things get strange... when i enter my email address and click on 'next' i cannot enter my passwort. seems like the text field is constantly loosing the focus. I can't click into the field to get the focus to enter the text.

BUT when i close the installer, start it again and hit the enter key instead of clicking on 'next' i can get to the next step and enter my passwort!

So far so good but theres another problem when selecting the license i cannot get past the next step when hitting enter. I need to click to next and now i am stuck. I cannnot enter the user there in the next screen after selecting the license.

I am on Ubuntu 20.04 with gnome/wayland. Did anyone observe the same problem?

Thank you for your solution. Unfortunately, I also encountered this problem. I searched for a long time and couldn't find a solution. This bug is really rare.

Guys, I have solution for this on linux.

This is due to Xwayland on linux which is still not very mature. So in this case keyboard and mouse input handling is problematic.

So switch your session to X11, It will fix the problem.

Switch desktop environment is not necessary.

I'm having the problem on both X11 and Wayland, so at least for me it's not a Wayland issue (this time). Switching to XFCE does work but I can't expect every client installing MATLAB in our organization to change their desktop environment as part the install process. According to the official MathWorks information this has been a known issue since at least R2018a (I'm trying to use R2024a). This really should have been fixed by now.

When you tried installing the MATLAB for the first time, you get the error: "..MATLAB Setup/bin/glnxa64/install_unix_legacy: not found".

This issue is possibly caused by downloading the MathWorks Installer for Linux and unzipping on a Windows machine. Be sure that you have unzipped the installer on Linux.

If the issue still persists use the -X and -K flags with the unzip command in Linux.

Note: You should have the flags installed in order to use them.

Also make sure you have the libraries needed to install MATLAB to avoid this issue.

So you can try re-installing the MATLAB using the above the solution.

Hi, the problem is not the missing file, but i cannot enter text in the fields of the installer gui.

As i wrote previously the installer is starting with bin/glnxa64/install_unix

I tried versions down to 2019b and this installer is working! I can enter text! But not the versions after 2019b. The installer GUI obviously changed after that version.

(I tried to unzip with the flags you mentioned. The installer is now starting fine but the problem with the gui persists)
