Ubuntu Boot Issues

Does this seem correct?

Open terminal and check your current kernel:

uname -r
DO NOT REMOVE THIS KERNEL!

Next, type the command below to view/list all installed kernels on your system.

dpkg --list | grep linux-image
Find all the kernels that lower than your current kernel. When you know which kernel to remove, continue below to remove it. Run the commands below to remove the kernel you selected.

sudo apt-get purge linux-image-x.x.x.x-generic
Finally, run the commands below to update grub2

sudo update-grub2
Reboot your system.

I'm not sure if that worked for me either.

I had to manually remove them.

I did not update grub

Any attempt to remove old packages results in:

~$ sudo apt-get purge linux-image-3.13.0-48-generic
Reading package lists... Done
Building dependency tree
Reading state information... Done
You might want to run 'apt-get -f install' to correct these:
The following packages have unmet dependencies:
 linux-image-extra-3.13.0-105-generic : Depends: linux-image-3.13.0-105-generic but it is not going to be installed
 linux-image-generic : Depends: linux-image-3.13.0-105-generic but it is not going to be installed
E: Unmet dependencies. Try 'apt-get -f install' with no packages (or specify a solution).

Have you tried the suggestion yet?

apt-get -f install

Yes, and the above is the result.

Ah, the issue appears to be that you allowed the disk to fill to a point that the automated tools can no longer manage it.

cd into /boot and give us an ls

Should be save to delete all of these. Copy them into /tmp if you are worried. Double check as you go, but these all seem to be unneeded.

Yep, exact issue I had.

YOU LET BOOT GET FULL. Lol. That's another feature, right @scottalanmiller

Not to make an excuse - but as someone who doesn't know much and is trying to learn Linux - I am not sure it can be said that I allowed it to happen.

Therefore - I blame it on the fain.

Who will now blame us.

Who deployed old Ubuntu in the first place? What server is this?

We took over this install

"It's been running for..." is another way of stating "it's been unmaintained for..."

Freed up enough space to move forward.

sudo rm -f (File list from above)

Running:

sudo apt-get -f install

Run the auto-cleanup script now,too.

I not sure what should be removed, but reading father down the article suggests just running sudo apt-get autoremove and this should be fine.

Welcome to one of the many unpolished bits of Ubuntu compared to the other enterprise Linux offerings. It needs manual maintenance of updates. It's ridiculous. Yes, the autoremove option is the proper way to handle it.

LOL - see it's things like this, or XS's lack of autodetection being on USB and not disabling/moving Log Files like VMWare that just make some of us pull our hair out.

Don't get me wrong - Windows 10's desire to constantly change the default viewer for PDFs is currently driving me mad!

And that is why Ubuntu is not recommended for newbies to Linux or those not looking for a little more challenge. It's not polished and easy like CentOS is. It's fine, it's a very good system. It's easier than Windows. But it's not comparable to the OSes that would be recommended for someone coming to the Linux world.

The real question would be... why are you running Ubuntu if this is seen as a frustration? I realize in this case, Ubiquiti controllers more or less require it and that's a huge pain that they have introduced. But in general, just don't use it.
