[xubuntu-users] libpng warning after latest update

[Hans Schneidhofer]

hello,

have tested some other software to start - all are running.
Only clementine doesn't and only with clementine this errormessage
appears.

Can it be, that clementine uses an outdated icc-profile ? And if so,
where can I get such an icc-profile ?

I started clementine from commandline and there this message appears.

My opinion is, that clementine doesn't have an updateded version for
the actual Ubuntu/Xubuntu-Version. Because looking at the homepage of
clementine, there are only versions for Precise, Trusty, Vivid, Wily,
and Xenial available for download. But no Focal Fossa.

Ubuntu offers clementine 1.40 for download, but it has this bug of the
wrong ICC profile.

So there are only two capabilities:
Ubuntu offers clementine 1.40 for download, but it has this bug of the
wrong ICC profile.

Either create your own ICC profile or wait until the bug has been
fixed.

At the moment I have no idea how to create my own icc profile. I've
never needed that either.


bye hans
