WordpressUpdate

Unfortunately - the default ubuntu install is a bit too broken to allow for an automated update.

The manual update process for simple releases is as follows:

0) Read the rel notes https://codex.wordpress.org/Version_4.9.8 (substitute the right version number)

1) Fetch a recent copy from https://wordpress.org/download/releases/

2) Then checked, unpacked and renamed it:

curl -O https://wordpress.org/wordpress-4.9.8.tar.gz openssl sha1 wordpress-4.9.8.tar.gz tar zxf wordpress-4.9.8.tar.gz sudo mv wordpress /usr/share/wordpress-4.9.8

3) Get some sanity

cd /usr/share

sudo chgrp -R www-data wordpress-4.9.8 sudo chmod -R o-rwx wordpress-4.9.8

4) Take risk (after scanning the release notes) and copy the old config across

sudo cp wordpress-4.9.7/wp-config.php wordpress-4.9.8

5) Test cursory and declared victory
