Issues during sen2cor processing

Dear all,

while running sen2cor I am facing the following issues:

Syntax error in metadata, see report file for details.
Parsing error:
Schema file: L2A_CAL_AC_GIPP.xsd
Details: Element 'wavelength', attribute 'c0': '' is not a valid value of the local atomic type. (line 0)
Syntax error in metadata, see report file for details.
Parsing error:
Schema file: L2A_GIPP.xsd
Details: Element 'PSD_Scheme', attribute 'PSD_Version': [facet 'length'] The value '' has a length of '0'; this differs from the allowed length of '2'. (line 0)
selected resolution is 60 m.

anyway the process ends successfully and I am getting the final product. I would like to know if these errors are influencing the final results and how to solve them.
I have also checked the other topics, but none of them was providing an useful solution (in my case).

Thanks in advance,
Francesco

It’s the libxml2 bug described here: https://github.com/senbox-org/sen2proc#recent-issue-with-anaconda
Either downgrade or upgrade it.

Perfect! Thanks so much
