Any update for this please?

Hi Shahir,

Installed libpng version 1.2.8  is very old . We need to cleanup this and then try to install latest one available.

Try cleaning up using 'dnf erase libpng' and see if that works. 

In case in you see any error using 'dnf erase', you can remove it using the approach we had discussed in another thread 'rpm -e <pkg>'. But then you need to cleanup all the dependency (recursively )  also manually . Below command will give you all the installed pkg which depends on libpng . 

# rpm -q --whatrequires libpng

After finding the dependency, first remove all the dependency before removing libpng 

Thanks

Hi Ranjit,

It got fixed by this method.

Thank you Ranjit @Ranjit Ranjan
