Yesterday I decided to try Flox. The flox program itself works fine in my initial testing, but I had an unpleasant experience installing it.
I’ve been running nix for a while, and with no issues, on Debian 12 using their nix, nix-bin and nix-setup-systemd packages.
If asked to boil it down the “unpleasantness” into four issues, I would say they were three:
- The website is optimized to hand me a
.deb(from a download drop down on the landing page), but even the installation instructions aren’t clear about the pros and cons of installing the Flox.deband replacing an existing nix installation vs simply installing Flox as just another binary within an existing nix installation. It is also not clear that the.debwill install nix for me. I found it unexpected and surprising that it did so. - I find here in the forums a general recommendation to keep using your current nix install, and use the “Nix - Generic” install option, if you’re happy with your current use of nix. This recommendation does not surface clearly on the website’s installation instructions. In my opinion, a question like “is nix already installed on your computer? [yes/no]” is an important one to consider and discuss on the installation page, but I don’t feel this is sufficiently discussed there.
- In the specific case of the interplay between Debian 12’s nix packaging and Flox’s
.deb, it appears that it is not possible to simply install one set of packages, then the other, and back and forth. This causes problems, and is best avoided (sadly). - The “Nix - Generic” install instructions ask me to ensure my nix is at least version 2.18 but don’t tell me how to check that version. The
nix --versionoutput on my system is2.8.0and things seem to work fine. This confusion is largely why I went through the trouble of trying to replace my nix install with the flox.debone.
What follows is a more detailed account of my tail of woe, but the above is a good summary.
Attempt 1: use flox-1.2.2.x86_64-linux.deb
I first attempted to install the deb directly. The .deb download is what
the landing page led me to believe was the best approach.
This did not go well due to a bug in the flox .deb package.
First attempt:
% sudo dpkg -i flox-1.2.2.x86_64-linux.deb
dpkg: regarding flox-1.2.2.x86_64-linux.deb containing flox:
flox conflicts with nix-setup-systemd
nix-setup-systemd (version 2.8.0-1.1) is present and installed.
dpkg: error processing archive flox-1.2.2.x86_64-linux.deb (--install):
conflicting packages - not installing flox
Errors were encountered while processing:
flox-1.2.2.x86_64-linux.deb
Okay, no problem, apt handles the removal of conflicting packages for me robustly, so
I attempted this:

Bug: the flox package doesn’t conflict with Debian’s nix-bin package. This breaks the install of the flox package.
Workaround: I uninstall nix-bin manually and try again. I do this with apt autoremove to remove the other unecessary packages as well:

The contents of the flox-installation.log mentioned above are below, but
the upshot is that it doesn’t like the nixbld users being numbered from
987-999. I believe these users are set up by the Debian nix packages.

It seems the build group nixbld already exists, but
with the UID 993. This script can't really handle
that right now, so I'm going to give up.
You can fix this by editing this script and changing the
NIX_BUILD_GROUP_ID variable near the top to from 30000
to 993 and re-run.

Revert to Debian’s nix packages, install flox under “Nix - Generic”
…it seems like the installation failure for Debian’s packages (above) was a red herring. After a reboot nix seems to be working fine.
So, since flox’s .deb is now uninstallable for me, I decide to use the
“Nix - Generic” installation option.
I am greeting with this warning on the install instructions page:
Please ensure you are using Nix version 2.18.0 or greater.
Bug: how am I supposed to check the nix version? How am I
My nix --version command prints 2.8.0 yet my flox installation works
fine. When I had flox installed, nix --version printed something like 2.17.1, which also doesn’t satisfy 2.18. So, I am left confused by this.
