Appimage v1.9.0 fails to run on Ubuntu 18.04

[mozzwald]

I run Linux Mint 19 (Ubuntu 18.04) and the latest version of Phoneboard v1.9.0 fails to run with the following error:

./phoneboard-v1.9.0-x86_64.AppImage: /lib/x86_64-linux-gnu/libm.so.6: version `GLIBC_2.29' not found (required by ./phoneboard-v1.9.0-x86_64.AppImage)

I was previously using v1.5.1 so I do not know when the problem was introduced.

It seems like the Ubuntu version was built against the wrong library version.
Im on ubuntu 18.04.

I would rebuild from source, which should resolve the problem, but I can’t seem to find the source anywhere.
