Upgrading to Ubuntu 18.04

I really like Ubuntu and I use it in different flavours on most of my computers at home. I tend to stick to the LTS and upgrade when the xx.04.1 version is out (in other words, when it prompts me to do so).

I know a fresh installation is usually the best but I also like to just do the upgrade and so far it worked perfectly for me. Except in one case.

I am going to put here my fix, hope it can help others.

from 16.04 to 18.04

The upgrade worked without any problem on all my machines except this one laptop. The laptop was previously upgraded from a 14 LTS and this could be the reason.

To prepare for upgrade I first ran

apt-get update && apt-get upgrade

Waited until it finished and successfully updated the 16.04 LTS, I didn’t need to run a dist-upgrade as there wasn’t any package held back.

I started the release upgrade from the terminal and everything seemed to go well until it failed:

The upgrade has completed but there were errors during the upgrade

Popped into a console and tried to fix it manually and force remove systemd-shim but it didn’t work. After a quick search I was able to resolve the problem renaming the file and forcing the pending installation to be completed

# mv /usr/share/dbus-1/system-services/org.freedesktop.systemd1.service{,bak}

# apt-get -f install

That worked but just to stay on the safe side I then ran my usual upgrade routine which consists of:

apt-get update && apt-get upgrade
apt-get dist-upgrade
apt-get autoremove && apt-get clean

Followed by another do-release-upgrade which happily showed that there was nothing else left. A quick reboot and we should be good, right? Wrong.

where is the dock?

The system booted and I was greeted by the new beautiful log in screen. Enter the password and… where is the dock?

Pressing the “windows” key I was able to see the default gnome dock and all my applications as Favourites, but the new shiny Ubuntu dock was nowhere to be found.

Even opening the settings showed a completely empty ‘dock’ section.

I tried installing gnome-tweaks but still no joy. In the end I figured out that something (an extension probably) was missing and a quick apt-cache search confirmed my suspicion.

# apt-get install gnome-shell-extension-appindicator \
gnome-shell-extension-ubuntu-dock \
gnome-shell-extension-system-monitor \
gnome-shell-extension-top-icons-plus \

After installing a few extensions I had the dock back and the configuration showing in the Settings. Not sure if all of these are needed, probably the ubuntu-dock alone would do.

Ugrade from Wheezy to Jessie

The time has come to upgrade my BanaPi (running Bananian) from Debian 7 (Wheezy) to Debian 8 (Jessie).
I am thankful for the amazing documentation. It’s going to be fun.

Other small projects I am running at the moment: solve a kernel panic on a Gentoo box, set up services on various VMs that I am running for experiment/fun/learning.

Study for my certifications and working on different Linux projects, this is a good way to spend a Satuday isn’t it?
But then I deserve a nice dinner out with my gf.


It’s quite fun if I think to it: I am pretty sure one of the old posts on the old version of my website was about me having fun installing Gentoo.

And now, here I am again: having fun with Gentoo.
Just created a VM and going to run again through the amazing documentation and the Gentoo Wiki.

For science!

Speaking of the old website, I need to find time to either import it into WordPress or just convert and link to the static version, which may be a lot easier…


Podcast fun

This is a bit new to me.

In the past I rarely had time to listen to anything going to work. And to be fair I had nothing, as in a device or a player, that would make it easier to play podcasts.

Now I am quite enjoying to listen to podcasts on my way to work. Most of them are related to Linux, this is my (little) list so far in an absolutely random order:

Any suggestion is more than welcome.
