fish: Missing default theme causes "No such theme: fish default" error on startup

Package Name

fish

Maintainer

@openwrt @Curtis Jiang jqqqqqqqqqq@gmail.com

OpenWrt Version

25.12.3

OpenWrt Target/Subtarget

mediatek/filogic

Steps to Reproduce

1. Install the fish package on OpenWrt.
2. Log in via SSH and start the fish shell.
3. Observe the missing theme error message printed above the prompt.

Actual Behaviour

When starting fish, it tries to load the fish default theme, but the theme files seem to be stripped from the OpenWrt package (likely to save space). This results in the following harmless but annoying error message on every startup:

No such theme: fish default
Searched directories: /root/.config/fish/themes /usr/share/fish/tools/web_config/themes

Workaround / Suggested Fix:
I was able to fix this issue manually by downloading the missing default.theme file (which is less than 1KB) directly from the upstream fish-shell repository:

mkdir -p /root/.config/fish/themes
wget -O /root/.config/fish/themes/default.theme \
https://raw.githubusercontent.com/fish-shell/fish-shell/a3984ace4a1cbe9059ed6fcee1332a1c80951e02/share/themes/default.theme
fish_config theme choose default

It would be great if this single default.theme file could be included in the base package, or if the build included a patch that stops fish from requesting this theme on startup.

Confirmation Checklist

• The package is maintained in this repository.
• I understand that issues related to the base OpenWrt repository or LuCI repository will be closed.
• I am reporting an issue for OpenWrt, not an unsupported fork.

Start by reproducing the fish startup error on OpenWrt 25.12.3 and inspect the package contents against the upstream share/themes/default.theme file. Check whether the base package can include default.theme, then verify that starting fish no longer prints the missing-theme error and that fish_config theme choose default works.
