ubuntu 20.04 lts

Yes, the latest LTS distribution of Ubuntu, 20.04 aka Focal Fossa, has been released. I’m raring to upgrade my desktop but there’s always a bit of work involved. Of course, with the COVID-19 pandemic in full swing, I’ve got plenty of time on my hands. But a few other things first. Watch this space.

Here’s my thoughts:
1. I need my Ubuntu server to be dedicated to music (and video); that’s why I got into the Linux game in the first place, and I’m all-in with Roon. I’ll do a clean install of 20.04, get 99% of it setup in no time at all.
2. The local copy of my production website(s) needs to go to a virtual machine. Great solution to a small problem.
3. Backup for photos and documents. Why not pay for a cloud service? I don’t like the idea of having a few hard drives laying around, I’m too OCD for that. Get it organized, put it in the cloud.

Now that’s a plan.

ubuntu 18.04 lts

Desktop upgrade time. The latest version of Ubuntu, 18.04 lts “Bionic Beaver,” was released last week, so I decided to upgrade my desktop computer in situ from 16.04LTS. There’s lots of changes between LTS versions, but the big change here was the switch from Compiz/Unity display manager and desktop to Xorg/Gnome. The reason why I upgrade is that the LTS version is supported until 2023, though I have to admit that having a new UI was enticing, especially with Gnome Shell extensions.
sudo update-manager -cd
After the above command to make the upgrade available to Software Updater, I had errors. Nonetheless, Bionic Beaver installed, and I rebooted. The first error was with ca-certificates during upgrade, which is a known Bug #1767453. The second was a broken intramfs, which I solved by updating it for the current kernel, sudo update-initramfs -c -k 4.15.0-20-generic.

Bigger issue I had was with Xorg/Gnome. When I’d go to log in, I’d get an empty screen, though intermittently between reboots it would work. Ugh. So I reinstalled Xorg/Gnome, by doing this:
sudo tasksel install ubuntu-desktop
then uninstalled Compiz/Unity by this:
sudo apt-get purge compiz compiz-plugins-main-default libcompizconfig0

It ends up the issue boiled down to one of the Display Managers, lightdm or gdm3. I decided to purge lightdm and use gdm3, which after the following thorough reinstallation, seems to be working:
apt-get update
sudo apt-get -d install --reinstall gdm3
sudo apt-get remove --purge gdm3
sudo apt-get install gdm3

I also installed gnome-tweak-tool to move the min/max buttons to the left, and the new theme, Communitheme, because after 8 years of Ambiance we all need a new Ubunutu theme! I also found some useful Gnome Shell extensions, which I installed via the “chrome” plugin in Firefox (go figure!). Oh, and this:
gsettings set org.gnome.shell.extensions.dash-to-dock show-apps-at-top true

After the perfunctory sudo apt-get update/dist-upgrade/autoremove, I went through many things, like local copies of websites, Openvpn, etc. and found they worked. MiniDLNA was also running but Logitech Media Server needed to be reinstalled (with a new version: 7.9.1 – 1522157629 @ Fri Mar 30 12:25:29 CEST 2018).

Mostly good, and a nice change of desktop scenery!

Ubuntu LTS the only way to go

When I first configured my cloud server, I was under the impression that I would just be trying it out, a test environment. It didn’t occur to me that I’d actually put it in production. Flippantly, I chose 12.10 instead of opting for 12.04 LTS, which is supported through May 2017. Well, 13.04 was already out of service by the time I got my notice that 12.10 was end-of-life, so the upgrade path was 12.10 -> 13.10 -> 14.04 LTS. Good news is that was easy enough to do. Bad news was 13.10 broke Apache’s Auth_MYSQL, which is used with AWSTATS in iRedMail. 

Like a good itjerk, I didn’t panic, went straight from 13.10 to 14.04 LTS, and would worry about the mess from there. Ends up that Auth_MYSQL isn’t supported in Apache 2.4.x, which is what 14.04LTS ships with. So I had to switch to Auth_DBD instead. Zhang at iRedMail was very helpful, and I got everything back up and working. BTW, Denyhosts is no longer supported in 14.04 LTS, that package had to be purged.

Apache2.conf needs this:

DBDriver mysql
DBDParams "host=127.0.0.1 port=3306 dbname=mail user=mail pass=xxxx

While awstats.conf needs:

AuthType Basic
AuthName "Authentication required"
AuthBasicProvider dbd
AuthDBDUserPWQuery "SELECT password FROM mailbox WHERE username=%s"
Require valid-user

Then, do this:
a2enmod auth_dbd
apt-get install libaprutil1-dbd-mysql
service apache restart

Moral of the story: Use LTS. Always. 

ubuntu 12.04 LTS precise pangolin

The latest version of Ununtu Linux operating system was released today. Named "Precise Pangolin" and carrying the number 12.04, it is a LTS (long term support) release that will be supported for the next five years.

Installation was painless after a reboot of the previous 11.10 was needed to get the "Distribution Upgrade" button to show up in Update Manager. Unity is still Unity, and I'm beginning to care less and less about specific applications, themes, HUD, global menus, etc. The work is what is important. Banshee was replaced by Rhythmbox; it also crashed when I attempted to run it, so it was quickly removed. I did get a few "internal errors" when Rhythmbox did its import, but smartly enough, I was informed that they were already reported. There was also a kernel update immediately after the upgrade.
