System Update froze - UbuntuMATE 16-04

Bret Busby-2
Hello.

I have tried to do a system update on this computer, which is (kind
of) running UbuntuMATE 16.04 .

The Software Updater shows

"Installing updates..."

and, under that, is
"Running post-installation trigger initramfs-tools"

(it is unfortunate that the window does not allow copying and pasting
of text in the window)

and it has been sitting there, with no progress for over half an hour
(it is on an i3CPU with 16GB of RAM, not an 8086 with 640kB of RAM).

The last two lines in the Details window (once again, it does not
allow copying and pasting), are

"
Processing triggers for initramfs-tools (0.122ubuntu8.11)...
update-initramfs: Generating /boot/initrd.img-4.4.0-127-generic
"

Above that, is this snapd thing gone wrong.

"
Setting up snapd (2.32.9) ...
Job for snapd.seeded.service failed because the control process exited
with error code.
...
snapd.seeded service couldn't start.
snapd.snap-repair.service is a disabled or a static unit, not starting it.
Setting up unattended upgrades (0.90ubuntu0.9) ...
(If only I could get rid of that thing - it sounds risky...)
"

So, I do not know whetehr it is the cause of the system upgrade fail,
but that snap d thing appears to be broken.

I am not game to kill the system update and try to reboot, in case it
can no longer find a valid kernel.

So, how dio I fix this broken system upgrade?

It has now, not changed, in about 50 minutes.

Go to terminal, either an app or via Ctrl-Alt-F2.

Become a real user:

sudo su -

unless you like this 'sudo' litany.

Find offending processes and kill them all.

Then

apt-get update
apt-get upgrade
apt-get dist-upgrade

If any of those fail, run

apt-get -f install

and repeat 'upgrade' and 'dist-upgrade'

You can also do

apt-get --purge remove snapd unattended-upgrades

at any time

Check, that you still have some kernels to boot:

update-grub

and reboot.

So, to remove unattended-upgrades, requires removing ubuntu-mate .

Okay - I found another pair of processes involving initramfs, so I
killed them, and, then, it let me run apt get update and apt-get
upgrade.

Now, it is stuck again, at the same place.

Quite likely, those are metapackages, i.e. contain nothing, but
references to other packages. Once you have a successfully completed
upgrade, you may check what they are:

apt-cache show ubuntu-mate

for example.

If you'd rather not remove them, those “services” can still be disabled:

systemctl disable snapd.service
systemctl mask snapd.service
systemctl disable unattended-upgrades.service
systemctl mask unattended-upgrades.service

So, after it got stuck in the initramfs stuff again, in killing the
two new initramfs setup processes, I get

Now, I do not know how many hours this

step is supposed to take, but I think something is wrong there.

It may take a while, depending on a system. I have seen it take up to 20
min. on some very low RAM cloud instances (even then there are
informative messages given), but you seem to have plenty of RAM.

I don't know what's the root of the problem in your case. You may have
to investigate, whether the process is actually doing something (disk
activity, resource usage), attache to it via strace -p <processID>, etc.

The service should be disable now. Can be checked:

systemctl list-unit-files --type=service |grep enabled

I am trying, for the third time, to send this reply. The first two
attempts, just disappeared.

In entering the command, I get

"
root@bret-Inspiron-580-UbuntuMATE:/home/bret# systemctl disable
unattended-upgrades.service
Synchronizing state of unattended-upgrades.service with SysV init with
/lib/systemd/systemd-sysv-install...

insserv: warning: current stop runlevel(s) (0 2 3 4 5 6) of script
`unattended-upgrades' overrides LSB defaults (0 6).
"

I do not understand that.

Is it something, about which, I should be concerned?

I believe this part of it is being looked into urgently - I don't have
details, but I've seen snapd developers talking about it over the last
day or two.

It has now been running (or, frozen) for more than an hour.

Running strace -p <pid> returns

And, after 3 hours, no change.

It is unfortunate.

I was going to update both my running 16.04 systems, for the Ubuntu
base security updates, but it seems too risky.

given that parts (specifically the mate software center "software-
boutique") are shipped as snap packages (to be upgradeable inependently
from the OS), this is probably not such a clever idea ... (especially
since the problem seems to be mainly related to the initramfs re-
generation)

After about 9 1/2 hours of no change, killed the initramfs processes.

I think it safer to leave the v16.04 Ubuntu base "security" updates,
until 16.04.(n+1) is released.
