That worked a treat, so thanks Nikolai5.

If you are based anywhere close to Keighley, treat yourself to a pint of Taylor's Landlord on me!

When the Update Manager attempts to install Updates, the process stops, and the following Error message appears: E: dpkg was interrupted, you must manually run 'dpkg --configure -a' to correct the problem. E: _cache->open() failed, please report. [/i] I've no idea how to follow these instructions. ...

Thanks Karl.
You are correct - this feature is not available on Mint 19.1

Thanks to everyone else who assisted. I'll just have to remember to periodically remove these obsolete kernels manually, now you have shown me how.

Looks like progress - the Update Manager icon is back and functioning. So many thanks for that!

The obsolete kernel packages have been uninstalled - how do I set Update Manager up to do this automatically please?

Karl I've entered the two commands as suggested, and this is the latter part of what appeared on screen: .........111 packages can be upgraded. Run 'apt list --upgradable' to see them.

Karl, this error message came up: jim@jim-ThinkPad-Edge-E531:~$ mintupdate jim@jim-ThinkPad-Edge-E531:~$ Traceback (most recent call last): File "/usr/lib/linuxmint/mintUpdate/mintUpdate.py", line 16, in <module> import pycurl ImportError: /usr/lib/x86_64-linux-gnu/libhogweed.so.4: symbol ...

I cannot launch Update Manager - clicking on the icon generates nothing at all.

Any suggestions please?

Thanks for responding.
It offered me a series of updates, which in turn I've accepted.

I don't appear to have an updates icon at the bottom right corner of my screen like I used to do - how do I restore this please?

I recently stopped receiving any updates, and suspect that this version of Mint is no longer supported? Where can I find out whether this is correct please? Assuming that this is the case, it means that I will need to install a new version - but which? And is there a guide on how to do this please? ...

Thanks and apologies for the delay in responding, for I have been away in a remote place with no internet access. I'm now back. I did come across the SANE project in my earlier searches but couldn't work out what it was, or how to use it, though I did suspect it might involve the Terminal, but I hav...

Cheers Administrollaattori but i don't understand your posting - probably because I'm out of my depth.

I went to scanimage.vidriotechnologies.com but don't see how that helps

Thanks Pjotr but that link doesn't solve the issue - Step 8 requires me to go to the Canon website and download the drivers for the scanning part - but these don't exist on the Canon site for Linux! Incidently this laptop is 32-bit. My printer prints but doesn't scan using Linux - the OS found the p...

Thanks for the link Ozo, but Simple-Scan doesn't work for me either.

So it's back to square one...........

Thanks Catweazel, but I can't get it to work for me. The scanning function on the printer works fine, and I've checked the connections - so it's looking like a driver issue. I downloaded sane-pixma.5.gz and opened it – still wouldn't scan. I've probably missed something very simple – can anyone poin...

My Canon PIXMA MP600 printer will print from my old laptop, but cannot scan documents – where can I find the missing 'scanning' drivers please? The Canon website does not offer them. My searches show that this is a common problem with other Canon printer models too, but following the links provided ...
