List of dpkg listing "linux-*" seems to be growing. Can I purge"
 

sudo dpkg -l | grep linux*
produces a whopping
28 responses

seems to me there used to be fewer. And some seem entirely excessive/redundant

I check this frequently and purge out-dated Header, Image and Module files but
it seems I might best purge quite a few of these. Can I?

Howdy!

There is a way to limit how many prior kernels you keep. I usually set mine to 3. Otherwise /boot or your distro area will soon be full of old kernels and support files. They are not easy to remove while in distro other than limit. Can boot to live and remove but search how to limit to the number you feel safe with.

You have five kernels and their support files installed get rid of the .71, .72 and .75 leaving the .79 and .80 versions installed. It is rather strange you have that many, Ubuntu usually offers to remove anything over two when you are updating with the apt autoremove command it will tell you about. Give it a try and see if it does remove them.

Thank you so much. The way you worded this gave me the insight to purge. Worked and it's better.

You are welcome.
