[HOWTO] Enable “Mark All Upgrades” in Synaptic on Linux Mint

If you are using Linux Mint Gnome or Linux Mint Debian Edition, you will notice that Ctrl+G or Mark All Upgrades is disabled. This has been done to prevent users from installing upgrades that have not been tested and verified to work by Linux Mint team. Read more in this discussion.

However, if you can take care of your packages and the problems that may arise, you may want to enable the handy feature. It can be done by following the instructions below.

Open up the terminal and remove synaptic completely:

sudo apt-get purge synaptic

Then edit out the line in the following file or remove it completely. However, if you want to be able to enable it, it is recommended to just disable the line using a # in the beginning of the line.


To edit it, you can open in any text editor as root. For example, to edit it using gedit, you may press Alt+F2 and enter the following:

gksu gedit /etc/linuxmint/adjustments/10-mintsystem-synaptic.overwrite

Make sure the line looks like the following by adding a # in the beginning of the line:

#/usr/lib/linuxmint/mintSystem/adjustments/synaptic.glade /usr/share/synaptic/glade/window_main.glade

Save the file and exit.
Then, install synaptic again:

sudo apt-get install synaptic

While removing Synaptic, note the packages being removed and install them back:

sudo apt-get install aptoncd apturl jockey-gtk mint-meta-gnome mint-meta-main mintupdate

That’s it. Open up synaptic and you should be able to use “Mark All Upgrades” again.

If you wish to disable the mark all upgrades again, just remove synaptic and then remove the # from the same file and save it. Then, re-install synaptic again.

Hope it helps.

[HOWTO] Install Virtualbox on Linux Mint Julia with USB Support and Shared Folders

There are many Virtualization solutions that run on Linux and of course Linux Mint. Oracle Virtualbox is a virtualization software available for Linux, Solaris, Windows and Mac, . It is available from the Linux Mint Julia Repositories and can be installed directly via Software Manager. However, if you install the open source version i.e. virtualbox-ose package, you will not be able to connect your USB devices and share folders between Guest and Host machines. File sharing can be set up in other ways, but if you wish to use one of your USB devices which has no Linux drivers, you may need to install Windows inside Virtualbox and connect your devices so that you can install drivers inside. In that case, you will need to install closed source edition of Virtualbox i.e. virtualbox-nonfree.

After you install virtualbox-nonfree, you will be able to run and install Guest operating systems inside. However, this version may nag you about updates being available. Linux Mint repositories will be updated regularly and you will be able to install latest version so you can disable the updates checking in Virtualbox>File>Preferences>Update.
