Endpoint re-install onto Oracle Linux Oracle 7.6

One of my colleagues uninstalled Sophos endpoint from an Oracle Linux 7.6 server and tried to re-install v 9.16.2 from a mounted location (as he usually does) but is getting an Input/output error /media /savshare /savi /sav.

Anyone able to advise on how to get this re-installed?

Thanks in advance

John
