Hello again - I’m trying to get flox installed in my vms using a cloud-init script (on Ubuntu, if that matters). If I add the apt source for flox (I get it by installing using the flox documentation then looking for the apt source), and try to install flox with apt install flox, I get an error that flox is an unknown package. Thanks for any pointers - I’m testing a brute force approach using runcmd in my cloud-init, but I was hoping for a kinder, gentler approach
Hej
On macos, so only verified in a docker container.
This should get you going:
# optional if you don't have wget,curl,or something similar yet
apt update
apt install wget
# get the public key for apt source verification
# and store it in /usr/share/keyrings
wget -P /usr/share/keyrings https://downloads.flox.dev/by-env/stable/deb/flox-archive-keyring.gpg
# add the debian source
echo 'deb [signed-by=/usr/share/keyrings/flox-archive-keyring.gpg] https://downloads.flox.dev/by-env/stable/deb stable/' > /etc/apt/sources.list.d/flox.list
# update apt
apt update
# install flox
apt install flox

According to @bryanhonof for cloud knit you’re looking for something like this:
# optional if you don't have wget,curl,or something similar yet
sudo apt-get --yes update
sudo apt-get --yes install wget
# get the public key for apt source verification
# and store it in /usr/share/keyrings
sudo wget -P /etc/apt/trusted.gpg.d/ https://downloads.flox.dev/by-env/stable/deb/flox-archive-keyring.gpg
# add the debian source
sudo sh -c "echo 'deb [signed-by=/etc/apt/trusted.gpg.d/flox-archive-keyring.gpg] https://downloads.flox.dev/by-env/stable/deb stable/' > /etc/apt/sources.list.d/flox.list"
# update apt
sudo apt-get --yes update
# install flox
sudo apt-get --yes install flox
Hej ysndr - let me give that a try. I essentially did the same thing. I bet the “apt update” step is what i neglected. If this works, then I can figure out the cloud-init setting to get the debian source set up declaratively, then it’s just a matter of adding “flox” to the list of packages.
I played around with it a little. This seems to work on an AWS EC2 Ubuntu node.
#cloud-config
packages:
- flox
apt:
sources:
flox:
source: deb https://downloads.flox.dev/by-env/stable/deb stable/

Bryan - bingo!
I think my issue with the manual testing was that I didn’t run the apt update after setting up the repo. This works fantastically

In case it’s useful to anyone, here’s where I ended up on my config. It’s a full set of dotfiles & etc. https://github.com/johnstegeman/dotfiles. The function that creates a Linux vm using clout-init is at https://github.com/johnstegeman/dotfiles/blob/main/dot_zsh_custom/config-file/functions/mcreate.tmpl
update: I also did a quick update of the readme and other docs in my repo, so it’s a little clearer which things I manage with homebrew/zinit/flox. My basic philosophy is to use zinit where possible, then flox if not possible, then homebrew/apt/scripts for the remainder. I did bump some things out of flox because when installing, it took up more disk space than I was willing to give up (an issue on my Linux vms where disk space is pretty small)
