Unable to Install new module from /admin/modules/install

It is still not working for me too, I tried uploading zip-file for context module

I can confirm this has been fixed and deployed.

I was able to install https://ftp.drupal.org/files/projects/devel-5.1.2.tar.gz and install it in a demo site.

Automatically closed - issue fixed for 2 weeks with no activity.

This is not working with instances that start with the Umami demo setup.
