OK, Jerry, will do. Have just tried it again. It first crashed out on unpacking then, when I repeated it, produced a report saying the system was up-to-date, though the packages it referred to were different to the ones that prompted the error report I quoted at first. So it looks as though it has sorted itself out - oryou have by other actions on the repository which I saw you had flagged up. Thanks as ever for your prompt help. I'll mark this as solved.

Upgrading should prevent this from happening again.

Not yet - I thought I might need to get to the bottom of this first.

Have you upgraded to 3.6 yet?

I've not updated for a week but when I tried to do so today I got the following message:

Install Updates Error log
===========================
Install Updates could not successfully download and install available updates.
Go to https://www.linuxliteos.com/forums/ and paste the log below into a new or existing thread for assistance.

============ Log ===========

E: Could not get lock /var/lib/dpkg/lock - open (11: Resource temporarily unavailable)
E: Unable to lock the administration directory (/var/lib/dpkg/), is another process using it?

I tried logging out and then backin again but got the same message.

Suggestions on how to tackle it would be much appreciated, thank you
