Ubuntu Mate 22 Jammy Jellyfish

[colink37]

How can I remove dozens of old Linux kernels from Jammy Jellyfish, please? Synaptic only gives me the option to install, with no opportunity to remove or delete from my nearly full disk. Simple advice would be truly appreciated. Thanks. Colin.

Dozens?

I am unfamiliar with the Mate desktop user interface so I cannot give you directions. On Gnome we have a Software Updater utility. This utility installs new kernels and removes old kernels as part of the update/upgrade process. Are we to assume the Mate does not have a similar utility?

In Gnome I can also update/upgrade using the terminal. When I do I sometimes get notification that there are kernels that are no longer needed and I can remove them using the autoremove command. Are you not able to do this in Mate?

sudo apt update
sudo apt upgrade
sudo apt autoremove

I do not normally use Synaptic to update/upgrade. I have used it in the past. It is possible to search for Linux kernels and mark some for removal. Be careful not to remove the kernel that you are using. Keep the two newest kernels.

Some commands to identify the kernels you already have

uname -r

will tell you the present kernel

ls -l .boot

will list all the kernels. Look for lines with vmlinuz. Search Synaptic for vmlinuz. Make a note of the kernels you have and identify the kernels you need to remove. Keep the two latest kernels. Synaptic will also let you remove files associated with the vmlinuz packages. To be safe remove one kernel and its associated packages at a time.

Regards

Thank you Grahammechanical. I appreciate your help and will give this a try. Colin.

What is the output of:

uname -a; echo; dpkg -l | grep linux-image | grep -v head

[Norm24]

sudo apt autoremove

I've used Mate for many years and this is all I've ever had to do to remove old kernals.The two newest should be left after executing that command.

Interesting. I'm a Mate user and currently running 22.04. I run sudo apt autoremove (and other 'clean' commands) daily via a script and I too have multiple kernels. sudo apt autoremove is not removing my kernels. I've just run the command manually as per below.

Hmm.. I did not understand this. Further reading suggests that the rc (release candidate) kernels listed above, for my system, are not actually installed - the only ones installed are the ii ones.

This is super easy

sudo dpkg -P `dpkg -l | grep linux-image | grep -v head | grep ^rc | awk {'print $2'}`

All those "rc" lines are packages you removed but old configs remain. This cleans them up

Hmm.. I did not understand this. Further reading suggests that the rc (release candidate) kernels listed above, for my system, are not actually installed - the only ones installed are the ii ones.

Correct

[Quarkrad]

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

 uname -a; echo; dpkg -l | grep linux-image | grep -v head

Thank you. I hopes this sorts out for colink37
