Problem trying to upgrade to 18.10

[kari0ca]

Hi there, i've been trying to upgrade to 18.10 from 18.04 with no sucess.

when i try to upgrade, i get this message:

Os pacotes a seguir serão mantidos em suas versões atuais: (wich means: The following packages will be kept in their current versions:)
gconf-service libfile-fcntllock-perl libgconf-2-4 liblocale-gettext-perl libnet-dbus-perl libnih1 libtext-iconv-perl libxml-parser-perl
0 pacotes atualizados, 0 pacotes novos instalados, 0 a serem removidos e 8 não atualizados. (0 upgraded, 0 newly installed, 0 to remove and 8 not upgraded)

I've tried:

dpkg --configure -a

and

sudo apt-get -f install

but no success, even tried to install the package that is in the list:

apt list --upgradable

this list of upgradable packages returns:

gconf-service/stable 3.2.6-4+b1 amd64 [upgradable from: 3.2.6-4ubuntu1]
libfile-fcntllock-perl/stable 0.22-3+b2 amd64 [upgradable from: 0.22-3build2]

libxml-parser-perl/stable 2.44-2+b1 amd64 [upgradable from: 2.44-2build3]

Does anyone knows how can i upgrade these packages?

Thanks in advance
