+As of 10th May 2026, Ubuntu 26.04 is still under testing to determine if EPrints can be successfully installed and if so if there are any issues with doing this, which require a different approach from the general approach for installing EPrints on Debian/Ubuntu Linux.
 ==== Current Issues ====
-; Segfault when creating EPrints database : If you use <code>bin/epadmin create pub</code> to create a new archive, once you approve the creation of the archive's database rather than prompting you for an appropriate username and password for a superuser that can create new database you get a segfault error like below. A resolution to this issue is currently being investigated.
+; XML library compatability problems : This will first occur at the point where you complete the credentials you want to use for your archive's database whilst you are running <code>bin/epadmin create pub</code>.  It will exhibit itself as either a segmentation fault or an error with the memory allocation (malloc) or free commands.  This is due to EPrints use of the <code>XML:LibXML</code> Perl library that ultimately uses the C library <tt>libxml2</tt>.  As of 10th May 2026, we have yet to defintively determine why this is happening.  [https://github.com/eprints/eprints3.4/issues/509 This GitHub issue] first raised for what appears to be the same issue with FreeBSD 14.3 provides some more detail about this problem.  It is likely this relates to [https://github.com/cpan-authors/XML-LibXML/issues/113 this XML::LibXML GitHub issue], so it may be a while before the libxml-libxml-perl package is updated but the XML::LibXML package on CPAN will likely be updated more promptly. Currently a possible workaround of disabling "expand_entities" and "load_ext_dtd" options in the calls to <code>XML::LibXML->new</code> in perl_lib/EPrints/XML/LibXML.pm on lines 69 and 73 is being evaluated,  However, further testing is still required to determine what impact this temporary mitigation may have on EPrints functionality.
