Stop audit from spamming dmesg by adding audit=0 to kernel params in *.conf file in /boot/loader/entries/
cd /boot/loader/entries/
sudo nano <the conf file? ### add " audio=0 " after "loglevel=0" so it says:
$ head -3 *.conf
title Endless OS 6.0.8 (ostree:0)
version 1
options rw splash plymouth.ignore-serial-consoles quiet loglevel=0 audit=0 ostr...
Note: Endless OS does not use the standard update-grub command or the /etc/default/grub file for persistent kernel options. Instead, it uses a different mechanism based on Boot Loader Specification (BLS) entries. such as example above.
While apt does not work on eos, note that you can install homebrew/linuxbrew package-manager, and it mostly works (except some gtk apps like gsmartcontrol crash). You will first need to temporarily get a curl command which is not included with eos.
1 So, among other places, you can download curl-amd64 pre-compiled static binary from https://github.com/moparisthebest/static-curl/releases
chmod a+x ~/Downloads/curl-amd64
$ whereis curl # says no curl is in path right now
curl:
cp ~/Downloads/curl-amd64 ~/.local/bin/curl
student@desk3:~/.local/bin$ whereis curl
curl: /sysroot/home/student/.local/bin/curl
$ curl -V
curl 8.17.0 (x86_64-pc-linux-musl) libcurl/8.17.0 OpenSSL/3.5.4 zlib/1.3.1 libssh2/1.11.1 nghttp2/1.65.0

Since we now have a working curl command, so we can run homebrew install script from brew.sh site.
/bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)"
==> Checking for `sudo` access (which may request your password)...
==> This script will install:
/home/linuxbrew/.linuxbrew/bin/brew
/home/linuxbrew/.linuxbrew/share/doc/homebrew
/home/linuxbrew/.linuxbrew/share/man/man1/brew.1
/home/linuxbrew/.linuxbrew/share/zsh/site-functions/_brew
/home/linuxbrew/.linuxbrew/etc/bash_completion.d/brew
/home/linuxbrew/.linuxbrew/Homebrew
Press RETURN/ENTER to continue or any other key to abort:
==> Found cURL: /home/linuxbrew/.linuxbrew/bin/curl
==> Installation successful!
==> Homebrew has enabled anonymous aggregate formulae and cask analytics.
Read the analytics documentation (and how to opt-out) here:
https://docs.brew.sh/Analytics
No analytics data has been sent yet (nor will any be during this install run).
==> Homebrew is run entirely by unpaid volunteers. Please consider donating:
https://github.com/Homebrew/brew#donations
==> Next steps:
- Run these commands in your terminal to add Homebrew to your PATH:
echo >> /sysroot/home/student/.bashrc <=== You can NOT do these 2 items to modify ~/.bashrc (See below)
echo 'eval "$(/home/linuxbrew/.linuxbrew/bin/brew shellenv bash)"' >> /sysroot/home/student/.bashrc
eval "$(/home/linuxbrew/.linuxbrew/bin/brew shellenv bash)"
- Install Homebrew's dependencies if you have sudo access:
sudo apt-get install build-essential <=== will NOT work since apt fails in eos. So try brew install gcc etc...
For more information, see:
https://docs.brew.sh/Homebrew-on-Linux
- We recommend that you install GCC:
brew install gcc
- Run brew help to get started
- Further documentation:
https://docs.brew.sh
They suggest echo >> /sysroot/home/student/.bashrcBUT you do NOT have to modify your .bashrc file.
Instead just create ~/brew-enable.shwith lines shown below
$ nano ~/brew-enable.sh ### paste in lines below
$ cat ~/brew-enable.sh ### should look something like this
eval "$(/home/linuxbrew/.linuxbrew/bin/brew shellenv bash)"
HOMEBREW_FORCE_BREWED_CURL=1
export HOMEBREW_FORCE_BREWED_CURL=1
# HOMEBREW_CURL_PATH=/home/linuxbrew/.linuxbrew/sbin/curl
# export HOMEBREW_CURL_PATH=/home/linuxbrew/.linuxbrew/sbin/curl
Then, anytime you want to use brew, just source ~/brew-enable.sh
student@desk3:~$ brew
bash: brew: command not found
student@desk3:~$ source ~/brew-enable.sh
student@desk3:~$ brew --version
Homebrew 5.0.11
student@desk3:~$ brew install curl tree nmap netcat ### use brew search to find all your favorites
### After installing commands, run mandb to index their man-pages
$ mandb
Purging old database entries in /home/linuxbrew/.linuxbrew/share/man...
Processing manual pages under /home/linuxbrew/.linuxbrew/share/man...
Updating index cache for path `/home/linuxbrew/.linuxbrew/share/man/man...
$ man brew
After you have the brew-installed curl, you want to use it instead of the staic-curl, so:
student@desk3:~$ which curl
/sysroot/home/student/.local/bin/curl
student@desk3:~$ mv ~/.local/bin/curl ~/.local/bin/curl-static
student@desk3:~$ which curl
/home/linuxbrew/.linuxbrew/bin/curl
student@desk3:~$
A lot of X/x11/x-org apps (like x11vnc) have issues due to wayland, but some run ok (like vncviewer in tiger-vnc package)...
$ brew install x11vnc

21/01/2026 20:55:38 Wayland display server detected.
21/01/2026 20:55:38 Wayland sessions are as of now only supported via -rawfb and the bundled deskshot utility. Exiting.
