[Bug 1833556] Re: Default, encrypted install runs out of /boot space after 2 months

[Jackalux]

Thanks very much for the reply, Brian.

I'm really grateful for the work that's gone into this as it used to be
a bane of my previous install (12.04).  That was merely an encrypted
/home with carefully researched and chosen (guessed) partition sizes;
this however is a default, entirely encrypted option of 18.04.

>From memory, I saw only one old kernel (I never see the purple boot menu
to select a kernel) and was amazed that I could be out of space.

Screenshot of folder properties for /boot from Nautilus is attached (I'm
obvs a Noob after all these years)

Current folder listing is:

I may always be making a mistake or misremembering something but I'm being as thorough as I know how.  I hope I'm not wasting any of your time!

Cheers

Title:
  Default, encrypted install runs out of /boot space after 2 months

Status in update-manager package in Ubuntu:
  Incomplete

Bug description:
  This bug is about the installer defaults, not this symptom of the bug.

  I installed a fresh encrypted* install of 18.04 on a laptop with a 750GB HDD.  The update-manager reported that I'd ran out of space within 2 months and could not perform updates.
  * AFAIK, encrypted installs place /boot in a separate partition

  'apt autoremove' didn't remove anything and only running the advice
  from http://tuxtweaks.com/2010/10/remove-old-kernels-in-ubuntu-with-
  one-command/ worked, which seems to leave me with no backup kernel.

  This would turn off Noobs who want something that doesn't require
  almost immediate, then ongoing, tech intervention.

  Does the installer need to change the allocated size of /boot in new
  installs?  Noobs will run back to Windoze if they encounter this... it
  looks like a fresh install has a shelf life of two months unless you
  learn to fiddle around under the bonnet/hood.

  Blessed are the coders!
