(If it's just a permission error, the solution might be trivial.)

thanks for your response - I tried to update via Snap, i have very limited linux experience - this installed but then got the disk permissions errors when trying to run 0.20.1 ..... so I have gone back to 0.18
maybe both versions are conflicting or something

If you Snap and you store the blockchain file on external storage, it's likely it's due to strict Snap permission, which doesn't allow application to access.
Check this thread https://bitcointalk.org/index.php?topic=5211567.0, few people mention how to fix the problem.

I tried to download a tar file from bitcoin.org, it has files inside but no real guide as to how to install

You just need to extract tar file, then open directory bin and double-click bitcoin-qt or run this command

Code:

./bitcoin-qt

If there's execution permission problem, enable execution from ubuntu file manager or run this command

Code:

chmod +x bitcoin-qt
