v0.1.12 requires GLIBC_2.43 and is missing AppImage artifact

[jimisola]

Description

The v0.1.12 release currently has two issues affecting usability on Linux:

1. The provided .deb package does not run on Ubuntu 25.10 due to a glibc version mismatch
2. The release is missing an AppImage artifact, which would otherwise provide a portable fallback

🧩 Issue : GLIBC incompatibility

The bundled libghostty.so requires GLIBC_2.43, while Ubuntu 25.10 provides glibc 2.42.
And the v0.1.12 release does not include an AppImage.

System information

• OS: Ubuntu 25.10 (questing)
• Architecture: amd64
• glibc: 2.42 (libc-bin 2.42-0ubuntu3.1)

Steps to reproduce

sudo dpkg -i ./limux_0.1.12_amd64.deb
limux

Actual result

limux: /lib/x86_64-linux-gnu/libm.so.6: version `GLIBC_2.43' not found (required by /usr/lib/limux/libghostty.so)

Verification

ldd --version
# → glibc 2.42

strings /usr/lib/limux/libghostty.so | grep GLIBC_
# includes GLIBC_2.43

Additional context

• All runtime dependencies are installed:
  • libgtk-4-1
  • libadwaita-1-0
  • libwebkitgtk-6.0-4
• The issue appears to stem from libghostty.so being built against a newer glibc than what is available on Ubuntu.

it does not work with my ubuntu 24.04 either. I have to rollback to 0.1.10

$ ldd /usr/lib/limux/libghostty.so
/usr/lib/limux/libghostty.so: /lib/x86_64-linux-gnu/libm.so.6: version `GLIBC_2.43' not found (required by /usr/lib/limux/libghostty.so)
$ ldd --version
ldd (Ubuntu GLIBC 2.39-0ubuntu8.7) 2.39

And v0.1.11 AppImage is not portable at all —— it requires glibc 2.43:

/tmp/.mount_Limux-6LX72R/usr/bin/limux: /lib/x86_64-linux-gnu/libc.so.6: version `GLIBC_2.38' not found (required by /tmp/.mount_Limux-6LX72R/usr/bin/limux)
/tmp/.mount_Limux-6LX72R/usr/bin/limux: /lib/x86_64-linux-gnu/libc.so.6: version `GLIBC_2.39' not found (required by /tmp/.mount_Limux-6LX72R/usr/bin/limux)
/tmp/.mount_Limux-6LX72R/usr/bin/limux: /lib/x86_64-linux-gnu/libm.so.6: version `GLIBC_2.43' not found (required by /tmp/.mount_Limux-6LX72R/usr/lib/libghostty.so)

i download the latest source code and build on my ubuntu 24.04. Everything works. So it is a build environment issue.

Implemented a fix for this in main.

What changed:

• release packaging now enforces a glibc baseline instead of silently shipping artifacts built against a newer host libc
• Linux release artifacts are set up to be built on Ubuntu 24.04 for a stable compatibility floor
• the AppImage path is included in the release pipeline again

This will be included in the next release.

Thank you. Keeping an eye out for the next release then.

Ubuntu 26.04 LTS is out in less than two weeks. Will be interesting to see if limux works out of the box then.

I don't think it's a good choice. deb/rpm is okay, but AppImage is for best compatibility, so should be built on some older OS to ensure it. Here's Gemini's suggestion: https://gemini.google.com/share/2733784665d4
