<p>Hi,</p>
<p><br>
</p>
<p>After upgrading from Ubuntu 16.04 to 18.04, I am getting the following error. The okular program opens but shows an error dialog that the pdf cannot be opened. On the terminal:</p>
<p></p>
<div>org.kde.okular.core: Invalid plugin factory for "/usr/lib/x86_64-linux-gnu/qt5/plugins/okular/generators/okularGenerator_poppler.so":"Cannot load library /usr/lib/x86_64-linux-gnu/qt5/plugins/okular/gener</div>
<div>ators/okularGenerator_poppler.so: (/usr/lib/x86_64-linux-gnu/libpoppler-qt5.so.1: undefined symbol: _ZN13GfxColorSpace17setDisplayProfileEPv)"</div>
<br>
<p></p>
<p>Does anybody know how to resolve this issue?</p>
<p><br>
</p>
<p>Thanks</p>
<p>Jonah</p>
