\[INS-30014] Unable to check whether the location specified is on CFS

In my case, I needed to open my hosts file (C:\Windows\System32\drivers\etc\hosts) and comment out the following:

# 192.168.0.111 host.docker.internal  
# 192.168.0.111 gateway.docker.internal  
# 127.0.0.1 kubernetes.docker.internal  

These seemed to be remnants of my old docker installation which has since been removed.

I tried other solutions from Stackoverflow, but none worked in my case. Here is the fix:

• Go to Control Panel > Network and Internet > Network Connections
• Disable
  • vEthernet (Docker)
  • vEthernet (Default switch)
• resume the install
• re-enable both disabled vEthernet.

In my case this was a permissions issue on the Oracle Home directory. If your Windows PC name is >= 16 characters in length, the name of the administrators group is affected, because only the first 15 characters are included. The mismatch between that first part of the name and the full name is what was causing the issue. DESKTOP-ASUS-ROG vs. DESKTOP-ASUS-RO in my case (notice the missing G). I renamed the PC to DESKTOPASUS, restarted the machine, and it worked without issue. The name discrepancy was apparent when looking at the security configuration of the folder when my system name was over max.

You can get your PC name by running hostname from the command line. If it's >= 16 characters, rename the PC to be <= 15 characters, and restart.

The underlying issue is indirectly discussed here in a different context: https://docs.microsoft.com/en-us/troubleshoot/windows-server/identity/naming-conventions-for-computer-domain-site-ou

Maximum name length: 15 characters.

By installing the software first and then running dbca to create the db I got it to work,

Execute hostname in command prompt

Add the hostname returned by hostname command next to IP address in windows hosts file. Also add the hostname with domain name next to it

9.115.154.54 LP1-AP-WIN73 LP1-AP-WIN73.yourdomain.com

Save hosts file and resume install
