Appimage: glibc undefined symbol on Debian Trixie

[shep7955]

Crash on appimage launch due to undefined symbol

Pineflash Version: 0.5.5

./pineflash-0.5.5-x86_64.AppImage: symbol lookup error: /tmp/.mount_pineflnNbfLg/usr/lib/libc.so.6: undefined symbol: __nptl_change_stack_perm, version GLIBC_PRIVATE

Same error on Ubuntu 25.04 (plucky)

To add to this, I am unable to use the apt package either. It is complaining about a missing dependency policykit-1 which appears to now be deprecated/no longer being distributed in Trixie.I was able to build and run from source however, but you will need to have the Rust toolchain installed and you must also have the libudev-dev package installed.

Hi,
can confirm, this issue also happens on latest CachyOS.

Also tested 0.5.3 and 0.5.4, same problem.

I confirm Debian 13 always show this:

$ pineflash-0.5.5-x86_64.AppImage
pineflash-0.5.5-x86_64.AppImage: symbol lookup error: /tmp/.mount_pineflNoiOOB/usr/lib/libc.so.6: undefined symbol: __nptl_change_stack_perm, version GLIBC_PRIVATE

Same errors here for both the Appimage and the .deb with Ubuntu 25.10
