Ubuntu – How to upgrade Nautilus in Ubuntu 14.04 Unity and Ubuntu based distros

Try executing:

grep ERROR /var/log/dist-upgrade/main.log

Hopefully this will show you the names of conflicting packages. For me it was (I broken long line to be easier to read):

2014-10-25 18:15:05,915 ERROR Dist-upgrade failed: 
    'The package 'postgresql-9.3-postgis-2.1' 
    is marked for removal but it is in the removal blacklist.

postgresql-9.3-postgis-2.1 is conflicting package here. It will probably be different one or some for you. You can then remove it/them by:

sudo apt-get remove conflicting-package-1 conflicting-package-2 ...

Then just restart distribution upgrade.

• The --update command only updates the files for the current version but does not upgrade to a newer version.

• If you want the latest rkhunter...

  • Download the tar.gz file from the sourceforge project page. Latest download is 1.4.2.

  • Go to your ~/Downloads directory (or if you downloaded someone else to that directory) and extract the tar.gz file, cd into the newly created directory and install it.

  • In commands after you downloaded it ...

    cd ~/Downloads
    tar xvfz rkhunter-{tab}
    cd rkhunter-{tab}
    sudo ./installer.sh --install
    

    (It will automatically fill out the version number when you press tab.)

After this you can check the version and update the resource file with:

sudo rkhunter --versioncheck
sudo rkhunter --update --propupd
sudo rkhunter --checkall

Regarding the error: see rkhunter.conf and comment out the SCRIPTWHITELIST=/usr/sbin/prelink or install prelink (Universe needs to be enabled) with

sudo apt-get install prelink

It is disabled at install and the config file /etc/default/prelink needs to be changed to enabled it (PRELINKING=yes) but that is not needed to prevent the error.
