<h2 id="backup-and-prep-process">Backup and prep process</h2>
<ul>
<li><p>Copied all documents and important files from Samsung laptop to removable hard drive. Used Lubuntu gui file manager which crashed at least twice, probably due to netbook limited RAM.</p></li>
<li><p>Found out that a direct upgrade from 16.04 LTS to 20.04 LTS is not possible, refer to the following links.</p>

</ul></li>
<li><p>Downloaded Lubuntu 20.04.1</p></li>
<li><p>Found a spare 32GB USB stick and copied all the files that were on it to a removable hard drive.</p></li>
<li><p>Opened downloaded Lubuntu image using Disk Image writer (1st time I've used this), wrote image to 32GB SD, found process very easy</p></li>
<li><p>On Samsung netbook hit F2 at boot time to select boot from USB</p></li>
<li><p>Booted from USB stick containing LUBUNTU 20.04.1</p></li>
</ul>
<h2 id="live-distro-1st-boot.">Live distro 1st boot.</h2>
<ul>
<li><p>Once booted I found the trackpad speed to be very slow and my first attempt at adjusting the speed in preferences made no difference.</p></li>
<li><p>Connected to WiFi, setting this up seemed much more clunky than previous connection method, however it did work.</p></li>
<li><p>Went to Youtube and played some video, everything worked fine, also found that volume keys on netbook worked.</p></li>
</ul>
<h2 id="install-process">Install Process</h2>
<ul>
<li><p>Went through install and selected manual partitioning,</p></li>
<li><p>Used existing swap on sda6 and format and mounted new Lubuntu root filesystem on sda7 replacing 16.04 with 20.04.1</p></li>
</ul>
<h2 id="after-first-boot">After first boot</h2>
<ul>
<li><p>Upon first boot was surprised that it had remembered my WiFi connection details and told me there were updates</p></li>
<li><p>It asked if I wanted to perform a full upgrade without giving any details. At the time I didn't know what this meant. I wasn't sure I would remain on an LTS or upgrade to 20.10. After the full upgrade I check OS release using the following command. This confirmed I was still running 20.04 LTS</p>
<pre><code>  cat /etc/os-release</code></pre></li>
<li><p>The logon screen has desktop options, by default it's set to Lubuntu, I found this to be a bit slow and unresponsive also the screen decoration on terminals was rather clunky taking up unnecessary screen space.</p></li>
<li><p>The next time I entered the logon screen I selected LXQT. I was pleased to find that this option was remembered. The netbook was now a bit more responsive though not quite as good as it was before the upgrade. The terminal screen was now much tidier and more usable.</p></li>
<li><p>Preferences / LXQT settings / Keyboard and mouse / Mouse and Touch Pad / Acceleration speed now 5.0 think was 0.1, also selected single click to activate item</p></li>
<li><p>Installed mc, ncdu, screen, pv, moc, ssh</p></li>
<li><p>Generated RSA ssh keys and copied them to Pi13, they installed with no problems and allowed me to SSH into my Pi13.</p></li>
<li><p>Copied all my files and documents from my portable hard drive back onto the laptop. This time I used mc "Midnight Commander" to copy the files back which I found much easier than using the GUI file manager the first time around. Midnight commander is an Ncurses file manager.</p></li>
<li><p>I had forgotten just how good the ncurses file manager Midnight commander is.</p></li>
<li><p>Midnight Commander gave a constant percentage progress of each individual file being copied and the overall progress which was very useful and reassuring with such a slow laptop. The first time around the laptop actually crashed a couple of times when I was using the LUBUNTU GUI file manager to try and copy the files from the laptop to the hard drive.</p></li>
<li><p>Also even though I generally use keyboard shortcuts for copy and paste operation I still tend to use the track pad at places when using a file manager. It's easy to limit yourself to keyboard navigation using mc. I found this to be greatly reassuring and I feel doing this makes the likelihood of disastrous errors much less likely.</p></li>
</ul>
<h2 id="general-thoughts-and-observations">General thoughts and Observations</h2>
<ul>
<li><p>The keyboard screen brightness buttons don't work however I can adjust it within preferences. Further investigation will be needed to resolve this minor annoyance if / when I get the time and inclination.</p></li>
<li><p>The netbook now has a much slower boot time</p></li>
<li><p>The netbook now feels a little sluggish but I think it's still perfectly usable. I have a feeling this might be the last upgrade this netbook sees as it's now getting a bit long in the tooth. It also has a broken power switch which I believe was a common fault. I have to use a pair of scissors to turn it on.</p></li>
</ul>
