Hi, I'm getting this error when trying to install any nodes:

What computer and operating system are you running?

Is the filesystem in fact read-only? - If you create a file in your home directory and reboot, is the file still there?

So Node-RED is installed on my Advantech Adam 6717, which is running Linux. I was able to install nodes before, but have not been able to ever since I was required to chang ssh permissions in my Windows .ssh folder, file "known_hosts" (see image). Is this what caused it? If so, how can I fix this? Thanks!

It seems unlikely, but isn't it possible to delete (or perhaps rename) known_hosts, connect again and find out?

Thanks jbudd! It turned out that the file system was in fact read-only. Setting it to read-write fixed it!
