## Surprises

### Changement de Debian/Wheezy -> Debian/Jessie

#### Apache2: [v2.2 -> v2.4][9]

##### site-avaiable
Les noms des fichiers se terminent [par .conf][10]

##### PhpMyAdmin

__Erreur__: `Fatal error:  require_once(): Failed opening required '/usr/share/php/php-gettext/gettext.inc' (include_path='.') in /usr/share/phpmyadmin/libraries/select_lang.lib.php on line 463`

__Remède__: Ajout de  _/usr/share/php/php-gettext/_ dans la directive _php_admin_value open_basedir_ du fichier de conf apache. (_Ref. :  [phpmyadmin symlinks error after ubuntu upgrade - superuser.com][10]_)

##### Owncloud logging

(Re)mettre en place les logs dans [_/var/log/owncloud/_ et le logrotate][11]

##### Manipulation des données ownCloud en local via CLI

Mise en place de [davfs2][14] pour le montage via _fstab_. Attention [doc.owncloud][13] est incomplète, voir aussi la [doc.ubuntu][12]

__erreur__: /sbin/mount.davfs: warning: the server does not support locks

/etc/fstab

~/.davfs2/secrets

/etc/davfs2/cert

/etc/davfs2/davfs2.conf
