[ Impact]
With the recent updates to the Ubuntu Desktop terminal theme defined in
this patch: https://salsa.debian.org/gnome-
team/ptyxis/-/blob/ubuntu/latest/debian/patches/ubuntu/color-
palette.patch?ref_type=heads the Windows Terminal profiles for Ubuntu on
WSL became out of sync. The new colours come with better contrast and
include a light theme.
We also noticed a small difference in how the terminal icon is rendered
compared to the Ubuntu website favicon. As the terminal scales down the
ICO file, it gives us the illusion of loosing one row of orange pixels
at the bottom. Tests showed that by shipping a smaller version of the
ICO file (32x32 pixels) we the desired look.
Patches submitted upstream are needed at least to the LTSes we expect to
build new images as part of their regular lifecycle (Noble and
Resolute).
+ Since new terminal profiles are only created when WSL creates new
+ instances and they never override existing profiles of the same name,
+ the new profile won't cause any change to users with existing instances.
+ Only new setups (after a clean-up if a previous Ubuntu profile existed)
+ can be affected.

[ Test Plan ]
On a Windows 11 device with Windows Terminal installed:
- On a preexisting Ubuntu on WSL instance install fastfetch (sudo apt install
fastfetch)
- Run fastfatch and record a screenshot for later visual comparison
- Access the terminal profile of that particular instance (Settings /
<INSTANCE_NAME> / Appearance)
- Observe the color values are different from those of ptyxis
(https://salsa.debian.org/gnome-team/ptyxis/-/blob/ubuntu/latest/debian/patches/ubuntu/color-palette.patch?ref_type=heads).
- Notice in the color schemes dropdown there is no Ubuntu-Light theme.
- Still inside the WSL instance, follow the steps in this guide to create a
chroot environment but do not perform any of the modifications described:
https://documentation.ubuntu.com/wsl/latest/howto/custom-ubuntu-distro/
- - With the bind-mounts set, chroot into it and install wsl-setup from
`-proposed`
+ - With the bind-mounts set, chroot into it and install wsl-setup from
`-proposed`
(chroot folder/ && sudo apt update -y && sudo apt install wsl-setup -t
<release>-proposed)
- Exit the chroot and pack the directory into a rootfs tarball with the
command described in that guide: `sudo tar --numeric-owner --absolute-names
--one-file-system -czvf ../MyNewUbuntu.tar .` .
- Move that tarball to the Windows filesystem.
- Remove all existing WSL instances (wsl --unregister <INSTANCE_NAME>)
- Remove all WSL terminal profiles (on the terminal app go to Settings /
<INSTANCE_NAME> / "Delete profile")
- Register a new WSL instance from the tarball created above: (wsl --install
--from-file <TARBALL-LOCATION-ON-WINDOWS> --name MyNewUbuntu)
- Follow the regular steps and when the shell is available just exit.
- Close the Windows Terminal
- Reopen the Windows Terminal **and launch the MyNewUbuntu instance from the
terminal drop down** to see the new theme applied.
- Install fastfetch (sudo apt install fastfetch)
- Run fastfetch and compare to the previous screenshot. Colours and font must
have changed. The icon change is harder to notice, but still noticeable. You
can compare before (the screenshot) and after (the current state) against the
favicon of the Ubuntu website as rendered by your favourite browser.
- Access the terminal profile for that distro in the Windows Terminal
settings.
- Compare the colour values against those of ptyxis
(https://salsa.debian.org/gnome-team/ptyxis/-/blob/ubuntu/latest/debian/patches/ubuntu/color-palette.patch?ref_type=heads).
- Notice in the color schemes dropdown that now there is the Ubuntu-Light
theme.
You should notice colours now aligned with ptyxis, the icon position
looking slightly more centered as well as the existence of a light
Ubuntu theme. The colour change in both ptyxis and now in WSL are made
for better accessibility, increasing contrast.
[ Where problems could occur ]
If the colours were not properly selected by our designers, we'd end up in a
worse condition for accessibility or deviate too much from our branding.
Desktop designers themselves were the ones pushing the changes in the
upstream repository. Since new terminal profiles are only created when WSL
creates new instances and they never override existing profiles of the same
name, the new profile won't cause any change to users with existing instances.
Only new setups (after a clean-up if a previous Ubuntu profile existed) can be
affected.
