Wow - your command in #8 did the trick. I now have:

 uname -a; echo; dpkg -l | grep linux-image | grep -v head
Linux dadubuntu 6.8.0-49-generic #49~22.04.1-Ubuntu SMP PREEMPT_DYNAMIC Wed Nov  6 17:42:15 UTC 2 x86_64 x86_64 x86_64 GNU/Linux

Thank you. I hopes this sorts out for colink37

No worries. If you read the command you can see what's going on

Also if yourself and the OP are so inclined this can also be done through gui using

Ubuntu Cleaner

Just be aware this is not an officially maintained package,it can be downloaded through Github.

My thanks to all of you who have been kind enough to suggest solutions. Please don’t think me rude. I’ve only had time to check my emails lately because I’m carer for my wife who’s ill. I’m grateful for all your suggestions and hope to be able to try them soon. Colin

[colink37]

To Grahammechanical, thank you. Sudo apt update, and upgrade, and autoremove caused some actions, but still my disk space was not reduced much. but afterwards I was able to remove about a dozen, yes, about 12, old generic kernels with Synaptic, however probably 100 old ‘bits’ were still left which couldn’t be marked for removal.
uname -r showed my latest ‘6.8.0-49-generic’ kernel after running,
but ls -l .boot returned screen message ‘cannot access ‘.boot’: No such file or directory’
Thanks for trying to help me. If I get a bit of time later, I’ll try ActionParsnips suggestion. Colin

Thank you ActionParsnip. Running your code
uname -a; echo; dpkg -l | grep linux-image | grep -v head gave me the result

Is this helpful? I still have about one hundred left over 'bits' displayed by Synaptic, which I cannot remove or delete using Synaptic. An example reads

Linux-image-5.15.0-1002-gke 5.15.0-1002.2 signed kernel image gke It is not installed, but is 11.2 Mb, presumably using **** space. 100 like these is leaving me with no free and usable dev disk space Any helpful advice would be appreciated. Do I have to delete these one by one from a Terminal screen with a 'remove' command? Colin.

You have two kernels. This isn't terrible. You can remove the old one with

sudo apt --purge remove linux-image-6.8.0-48-generic
sudo apt autoremove

[yancek]

In your initial post, you indicate you have a nearly full disk but have not posted any exact information on it. Run the df -h command and it will show the size and used for each mounted partition. Have you checked your log files? That's often where a disk fills up. You can get that info with: sudo du -c -h /var/log. You can run that command on other directories to see how much data you have.

[colink37]

Thank you Yancek, I’ll give that a try tomorrow. Colin.

[colink37]

Thank you ActionParsnip. I’ll give that a shot tomorrow. Colin.
