I’ve done a little tuning to my WordPress setup. In order to keep up to date, I’ve switched from the Ubuntu installation to a downloaded installation under
/opt/wordpress. This is owned by my user and served by
apache running as
www-data. Updates are done using the sftp add-on.
I added myself to the

is_filefunction appear to fail as WordPress reports the download contains no files. This is likely the same issue as for the
