Lab 4.6 Install LXD Heads-up

rogerh

The following command had a couple of issues (cut and paste from the lab failed). Both were related to the number '1' vs the letter 'l'. the font used made the two characters hard to distinguish:

sudo apt install -y acl autoconf dnsmasq-base git golanglibacl1-dev libcap-dev liblxc1 liblxc-dev libtool libudev-dev libuv1-dev makepkg-config rsync

So if you are having 'unable to locate package' errors when trying to use this command, that's why. focus on the packages that can't be found and change out the characters accordingly.

Hi @rogerh,

I agree that when zoomed out, the two characters are hard to distinguish, but that only impacts users who are typing the command manually. In that situation I recommend zooming in, it will make characters much easier to distinguish.

However, a copy and then paste of the command ensures that each character is recognized automatically, regardless of the font used.

Hi @chrispokorni ,

Unfortunately I did that - copied and pasted the command and it failed. That's when I started looking at the syntax more carefully. Anyway it now works.

Best,

Roger

so finally, which was the right command?

Installing like this would it all right?
sudo apt install lxd

Hi @lipiss ,

It seems that LXD is now being managed by 'snap'. Are you using Ubuntu?

I just did the following:

luis@ubuntu18server:~$ sudo snap install lxd
[sudo] password for luis:
lxd 4.8 from Canonical✓ installed

You can take a look to the official LXD documentation:

https://linuxcontainers.org/lxd/getting-started-cli/#ubuntu

I hope that helps,
Luis.

Just curious.
I have wiped snap off of my Ubuntu systems. (Don't ask..)
However, if I do apt-get install lxd it wants to install snap and lxd. So far I have not run into any other software that forces me to use snap. So it reverses sudo apt autoremvove --purge snapd gnome-software-plugin-snap
as I have done on many systems. So it returns snap from the graveyard.

Hi @coop ,

It seems there is a similar debacle about installing Chromium on Ubuntu, because it installs the snap package instead -at least on Ubuntu 20.04, not Ubuntu 18.04.

Look at this:

luis@ubuntu20:~$ sudo apt install chromium-browser

[...]

you could install google-chrome-stable instead unless you need chromium I guess. We purge snap from all LF Ubuntu VM's that we make available, because it can double the size of the compressed VM's since it adds GBs of incompressible material; even its cleanup utility (which takes work to find and configure, it is hidden) leaves most of it. But any student can easily add it back in even the need it.

After issued the following command, the lxd binary does not exist in my VM:
apt install -y acl autoconf dnsmasq-base git golang libacl1-dev libcap-dev liblxc1 liblxc-dev libtool libudev-dev libuv1-dev make pkg-config rsync

$ cat /etc/os-release | grep VERSION=
VERSION="18.04.5 LTS (Bionic Beaver)"

At last I installed the binary:
# apt install lxd

Hi @proliant,

Thank you for your feedback. The installation steps will be revised in a future course update release.

@lipiss something jumbled the whitespace when you copied from the lab. There is no golanglibacl1-dev because golang and libacl1-dev are separate; a space should separate them in the list. Likewise, makepkg-config also doesn't work because make and pkg-config should also have a space in between.

Interestingly both of those are split by newlines in the lab document. Gotta watch out for that
