Broken UK manual issue

Hello everyone.
I have a problem fixing a build error in the Ukrainian translation module.

There is a build output:

The fact is that there is no file
"/var/www/doc-editor/data/phpdoc-all/doc-base/manual.xml" in "All files"
tab.
If anyone knows why this happened, please explain.
