Can not upgrade from 9.1 to 9.2 or 9.3, --HELP

I went through postgres website since yesterday and can not upgrade my
postgresql from 9.1 to anything greater. At first I did pgupgrade and was
told to install postgres-xc, when I installed it, it removed 9.1 and I could
not log into it. I was able to recover it and when I the steps from
https://wiki.postgresql.org/wiki/Apt I get  pgadmin3 : Depends:
libwxbase2.8-0 (>= 2.8.12.1+dfsg) but 2.8.12.1-14ubuntu1.1 is to be
installed
            Depends: libwxgtk2.8-0 (>= 2.8.12.1+dfsg) but
2.8.12.1-14ubuntu1.1 is to be installed.

Do I just install  libwxgtk2.8-0?
