18.2 was released a few days ago, so I thought I’d throw it against my 18c instance and see how things played out. This was just a single instance database, running with a single pluggable.
Step 1 for me was to download the latest OPatch. To be honest, I don’t even check whether I already have the latest version in any installed ORACLE_HOME anymore. If I’m going to apply a patch, I’m always going to download the latest OPatch unless the README explicitly tells me some reason why I should not. I figure getting the latest version reduces the chances I’ll hit problems. For me, I grabbed version “188.8.131.52.13”, but your experience may differ depending on when you encountered upon this post.
So I then downloaded patch 27676517 (note, this does not include patches for the JVM which are done separately).
From there is was just a case of following the README instructions and I had no dramas at all. Software patching went through smoothly:

And the datapatch stage to update the database(s) also went through without any problems.

So all in all, a painless and straightforward experience for me.
One minor annoyance for me was the “Bugs Fixed” document. The README references this as:
but that document is not accessible currently. However, if you follow a different link in the README
then you will get to the document which contains the list of fixes etc.
Footnote: If you are not familiar with the new nomenclature of “Patch”, “Release Update”, etc etc, here is a good place to start
and follow the various links within that post for more information.
Addenda: When it comes to the ‘datapatch’ script, the README is perhaps a little ambiguous. More on that here
