Hello,
I am installing openfoam but the following error is occuring time and again

E: Problem executing scripts APT::Update::Post-Invoke-Success 'if /usr/bin/test -w /var/cache/app-info -a -e /usr/bin/appstreamcli; then appstreamcli refresh > /dev/null; fi'
E: Sub-process returned an error code

Can someone suggest me what kind of error is it and how to tackle it?
Regards,

Quick answer: I don't know if you've managed to solve this or not, but that error message alone is not enough to be certain of what is the problem.

If you still have this problems, please give more of the output message that it gives you.
