Broken UK manual issue

Hello everyone. I have a problem fixing a build error in the Ukrainian translation module. There is a build output: > configure.php: $Id: configure.php 344134 2018-01-31 12:33:50Z vrana $ > PHP version: 7.3.14-1~deb10u1 > > Checking for source directory... /var/www/doc-editor/data/phpdoc-all/doc-base/ > Checking for output filename... /var/www/doc-editor/data/phpdoc-all/doc-base/.manual.xml > Checking whether to include CHM... no > Checking for PHP executable... /usr/bin/php7.3 > Checking for language to build... uk > Checking whether the language is supported... yes > Checking for partial build... no > Checking whether to enable detailed XML error messages... yes > Checking libxml version... 2.9.4 > Checking whether to enable detailed error reporting (may segfault)... yes > Checking whether to optimize out the DTD (performance gain, but segfaults)... yes > Generating /var/www/doc-editor/data/phpdoc-all/doc-base/manual.xml... done > Generating /var/www/doc-editor/data/phpdoc-all/doc-base/install-unix.xml... done > Generating /var/www/doc-editor/data/phpdoc-all/doc-base/install-win.xml... done > Generating /var/www/doc-editor/data/phpdoc-all/doc-base/developer.template.xml... done > Generating /var/www/doc-editor/data/phpdoc-all/doc-base/scripts/file-entities.php... done > Iterating over extension specific version files...

If anyone knows why this happened, please explain.
