Plugin installation warnings after clean local install of WP 3.91

I performed a fresh WP install this week and it seems ok except I get the following error when installing all plugins: Warning: An unexpected error occurred. Something may be wrong with or this server’s configuration. Attached is the screen shot. I have only installed WP on 3 other occasions but have not experienced this. SHould I try to reinstall or do think there is a rational explanation and a way to fix it. Thanks
