Recovery from failed Upgrade from 16.04 LTS to 18.04 LTS dpkg errors.

[rsteinmetz70112]

OK, I'm on my 4th of 7 upgrades from 16.04 to 18.04. 2 went well 2 went not so well.

The one I working on now went not so well as somewhere a number of packages failed to download and configure leaving me with a partially working system,. I've not got the computer almost working except I can't run

# apt upgrade

or

# dpkg --configure -a

or

 # apt autoremove

because of dpkg errors that seem to be caused by conflicts between different packages that seem to be very similar.

Here is some output

# dpkg --configure -a
dpkg: dependency problems prevent configuration of linux-tools-4.15.0-45-generic:

I'm not sure why I have two versions of linux-tools trying to be installed.

whne I run

# apt install -f

Part of the output is this:

This seems to indicate

linux-hwe-tools-4.15.0-43 4.15.0-43.46~16.04.1

is already installed.
So the question is should I remove the partially installed packages and hope for the best?

rsteinmetz70112; Hello -

I get this ball started rolling.
The question is why did not the kernels fully install ?
what shows for a "out of disk space" possibility ?

df -h
df -i

and next we need to know what kernels are installed:

sudo dpkg -l | grep linux-
ls -al /boot/

The current 18.04 kernel is:

sysop@x1804mini:~$ uname -r
4.15.0-46-generic
sysop@x1804mini:~$

see what story gets told

[rsteinmetz70112]

The kernel did fully install and the computer boots. During the upgrade something went wrong and a lot of packages weren't configured because some packages didn't install. I fixed much of that with dpkg but now I can't update or upgrade because of the dependency problems.

There is plenty of disk space.

I think the three versions of linux-tools are in conflict, and I'm not sure which one or ones I need.

linux-hwe-tools-4.15.0-43 (installed)
linux-tools-4.15.0-45 (not installed)
linux-tools-4.15.0-43 (not installed)

If the Linux-hwe-tools-4.15.0.43 is an equivalent alternative to the other two I may be fine.

These two packages won't install

linux-tools-4.15.0-45-generic
linux-tools-4.15.0-43-generic

It looks to me like -45 package should supersede the -43 package and I shouldn't need both.
But I'm in unfamiliar territory.

I suppose I could remove the two -generic packages and see if the resolves the issue.
But I am concerned that will break something else, so I'm being careful.

Potential commands to remove the packages are:

# apt <remove>

or

# dpkg -remove <package>

or

 dpkg -purge <package>

linux-hwe-tools-4.15.0-43 is a leftover from 16.04. It should have been removed during the release upgrade. The other packages belong to 18.04.

[rsteinmetz70112]

I'll try to remove and install it then.

I'll see if I can do it on the running system or if I have to do it in a chroot session, after downloading the correct packages.

[rsteinmetz70112]

If this should have been upgraded and for some reason wasn't is there a way to upgrade or replace a single package?

It seems this error seems to be saying dpkg can't overwrite a file :

dpkg: error processing archive /var/cache/apt/archives/linux-tools-4.15.0-43_4.15.0-43.46_amd64.deb (--unpack):

Have you tried to remove it with

sudo dpkg --purge linux-hwe-tools-4.15.0-43

[rsteinmetz70112]

Not yet. It's at another site and I won't be there again until till next week. Fortunately it's not a production system and I can afford to wait on this one.

I am a little concerned that if I try to remove it with dpkg it will break a lot of dependencies.

I also don't understand if it's been replaced why won't the new package simply install over it.

Am I wrong, or have you forgotten the

# apt update

after changing the repositories in /etc/apt/sources.list ?

I can try again, and check it but I'm pretty sure I've run

apt upgrade

and apparently it marked the need to install the packages but when I run

 apt upgrade

or

 dpkg --configure

it fails due to dependency issues. I can't install the packages

apt upgrade

has downloaded, because of the dependency issues.

I found this thread which may hold some clues:
