I trying to install XAMPP on my ubuntu 18.04 but I got this warning from libpng by running this command: 

sudo ./xampp-linux-x64-7.3.9-0-installer.run

The thing need to be considered is that I got this warning on all versions of XAMPP. Someone already asks the same question there libpng warning : Application jmp_buf size changed - while installing XAMPP but the answer is useless. Its a humble request please help.
I am not able to install XAMPP since last two days.

Solved this by running the xampp installer with strace:

sudo strace -Ff -tt ./xampp-linux-x64-7.4.2-0-installer.run 2>&1 | tee strace-xampp.log

Opened strace-xampp.log and saw at the very end of the log that NotoColorEmoji.ttf crashed the app

[pid 44306] 06:00:07.874986 stat("/usr/share/fonts/truetype/noto/NotoColorEmoji.ttf", {st_mode=S_IFREG|0644, st_size=7745408, ...}) = 0

06:00:07.975443 +++ killed by SIGSEGV (core dumped) +++

So I deleted the whole font by running

sudo rm -rf /usr/share/fonts/truetype/noto

Hope this helps.
