<p class="MsoNormal"><span lang="EN-US"><o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="EN-US">I have been using GDAL to access online data sources in netCDF successfully.<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US">With Ubuntu 20.04, this unfortunately no longer works with the netCDF driver.<o:p></o:p></span></p>
<p class="MsoNormal"><span lang="EN-US"><o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="EN-US">Here is a reproducible example:<o:p></o:p></span></p>

<p class="MsoNormal"><span lang="EN-US"><o:p> </o:p></span></p>
<p class="MsoNormal"><span lang="EN-US">The original error message (before working around the HDF5 driver) has been that permissions for the userfaultfd system call were denied. But if I specify the netCDF driver, the format is not recognized. Downloading the
dataset and opening It locally works.<o:p></o:p></span></p>
