Eclipse. Come aggiornarlo da 3.8 a 5.2 oxigen?

Ciao a tutti,

Nei repository di Ubuntu mate 16.04 si può installare la versione di Eclipse 3.8 ed è quella che ho installata. Seguendo questa Procedura per aggiornarlo. Quando poi arrivo al punto 3 mi dà appunto errore a causa dei conflitti, restituendo:

Cannot complete the install because of a conflicting dependency. Software being installed: Eclipse CVS Client Resources 1.4.403.v20180301-0715 (org.eclipse.cvs.source.feature.group 1.4.403.v20180301-0715) Software currently installed: Eclipse CVS Client 1.3.200.dist-7B79FJJ9exZ_ (org.eclipse.cvs.feature.group 1.3.200.dist-7B79FJJ9exZ_) Only one of the following can be installed at once: Eclipse CVS Client 1.2.0.dist (org.eclipse.cvs 1.2.0.dist) Eclipse CVS Client 1.4.403.v20180301-0715 (org.eclipse.cvs 1.4.403.v20180301-0715) Cannot satisfy dependency: From: Eclipse CVS Client 1.3.200.dist-7B79FJJ9exZ_ (org.eclipse.cvs.feature.group 1.3.200.dist-7B79FJJ9exZ_) To: org.eclipse.cvs [1.2.0.dist] Cannot satisfy dependency: From: Eclipse CVS Client 1.4.403.v20180301-0715 (org.eclipse.cvs.feature.group 1.4.403.v20180301-0715) To: org.eclipse.cvs [1.4.403.v20180301-0715] Cannot satisfy dependency: From: Eclipse CVS Client Resources 1.4.403.v20180301-0715 (org.eclipse.cvs.source.feature.group 1.4.403.v20180301-0715) To: org.eclipse.cvs.feature.group [1.4.403.v20180301-0715]

Sapreste come risolvere il problema senza che vada a causare problemi nel sistema?
