How to Install KeePass in Linux Mint / Ubuntu

Technically, we can install KeePass through Ubuntu Software…

…or the Linux Mint Software Manager.

However, if we install KeePass through these channels, we won’t be getting the very latest version. And where’s the fun in that?

Add the KeePass repository

For the latest and greatest KeePass installation on Linux, we must add a repository. We just need to fire up a terminal, with Ctrl+Alt+T, and type:

sudo apt-add-repository ppa:jtaylor/keepass -y

Just a reminder for Linux newcomers, when we use the “sudo” command, and we enter our password, nothing will show as we type, no stars or dots or anything. We just enter the password and hit Enter.

For more information about Linux terminal commands, check out our guide:

After successfully adding the repository, we need to do an update with:

sudo apt-get update

Install KeePass

Once the update is done, and we had no error messages, we type the following command to install KeePass:

sudo apt-get install keepass2 -y

Once we finish with the installation, we will find KeePass at the Mint menu, in the Accessories section.

In Ubuntu, we just need to search for it on the Dash.

How to completely disable Cortana on Windows 10c

Cortana is very integrated with Windows Search and fully disabling it will break Search. However, if you would like to keep Search functional, you can just disable the “Cortana-y” parts of Cortana.

  2. Type GPedit.msc and hit Enter or OK to open Local Group Policy Editor. Navigate to Local Computer Policy -> Computer Configuration -> Administrative Templates -> Windows Components -> Search.
  3. In the right pane, double click on policy named Allow Cortana.
  4. Select the Disabled radio button.
  5. Restart the PC and Cortana and Bing Search will be disabled. (May work after signing out and in again)

Policy Description

This policy setting specifies whether Cortana is allowed on the device.

If you enable or don’t configure this setting, Cortana will be allowed on the device. If you disable this setting, Cortana will be turned off.

With this set, users will still be able to use search to find things on the device and on the Internet.

Safest way to clean up boot partition – Ubuntu 14.04LTS-x64

Reference

Case I: if /boot is not 100% full and apt is working

1. Check the current kernel version

$ uname -r 

It will shows the list like below:

3.19.0-64-generic

2. Remove the OLD kernels

2.a. List the old kernel

$ sudo dpkg --list 'linux-image*'|awk '{ if ($1=="ii") print $2}'|grep -v `uname -r`

You will get the list of images something like below:

linux-image-3.19.0-25-generic
linux-image-3.19.0-56-generic
linux-image-3.19.0-58-generic
linux-image-3.19.0-59-generic
linux-image-3.19.0-61-generic
linux-image-3.19.0-65-generic
linux-image-extra-3.19.0-25-generic
linux-image-extra-3.19.0-56-generic
linux-image-extra-3.19.0-58-generic
linux-image-extra-3.19.0-59-generic
linux-image-extra-3.19.0-61-generic

2.b. Now its time to remove old kernel one by one as

$ sudo apt-get purge linux-image-3.19.0-25-generic
$ sudo apt-get purge linux-image-3.19.0-56-generic
$ sudo apt-get purge linux-image-3.19.0-58-generic
$ sudo apt-get purge linux-image-3.19.0-59-generic
$ sudo apt-get purge linux-image-3.19.0-61-generic
$ sudo apt-get purge linux-image-3.19.0-65-generic

When you’re done removing the older kernels, you can run this to remove ever packages you won’t need anymore:

$ sudo apt-get autoremove

And finally you can run this to update grub kernel list:

$ sudo update-grub

Case II: Can’t Use apt i.e. /boot is 100% full

NOTE: this is only if you can’t use apt to clean up due to a 100% full /boot

1. Get the list of kernel images

Get the list of kernel images and determine what you can do without. This command will show installed kernels except the currently running one

$ sudo dpkg --list 'linux-image*'|awk '{ if ($1=="ii") print $2}'|grep -v `uname -r`

You will get the list of images somethign like below:

linux-image-3.19.0-25-generic
linux-image-3.19.0-56-generic
linux-image-3.19.0-58-generic
linux-image-3.19.0-59-generic
linux-image-3.19.0-61-generic
linux-image-3.19.0-65-generic
linux-image-extra-3.19.0-25-generic
linux-image-extra-3.19.0-56-generic
linux-image-extra-3.19.0-58-generic
linux-image-extra-3.19.0-59-generic
linux-image-extra-3.19.0-61-generic

2. Prepare Delete

Craft a command to delete all files in /boot for kernels that don’t matter to you using brace expansion to keep you sane. Remember to exclude the current and two newest kernel images. From above Example, it’s

sudo rm -rf /boot/*-3.19.0-{25,56,58,59,61,65}-*

3. Clean up what’s making apt grumpy about a partial install.

sudo apt-get -f install

4. Autoremove

Finally, autoremove to clear out the old kernel image packages that have been orphaned by the manual boot clean.

sudo apt-get autoremove

5. Update Grub

sudo update-grub

6. Now you can update, install packages

sudo apt-get update

Transparent system panel in Linux Mint 18.x Cinnamon

By default in Linux Mint 18.x Cinnamon theme in the desktop system panel is black and opaque. In the settings panel there is no option or setting the transparency panel. But in Linux file system is open for user and administrative changes that where in configuration files it is possible to make the necessary changes. Something that is not provided by the developers, we will try to do it yourself.

Edit the file default theme’s cinnamon.css with administrator’s rights:
Terminal
Shekin@mypc~$
sudo xed /usr/share/themes/Linux\ Mint/cinnamon/cinnamon.css

When you open the text editor with the file cinnamon.css, press Ctrl+F in the search box copy/paste the #panel, and then click Find:

Transparent system panel in Linux Mint 18.x Cinnamon

Now at the end of this section (panel), add the line (copy/paste):

Terminal
Shekin@mypc~$
background-color: rgba(175,175,175,0.05);

Transparent system panel in Linux Mint 18.x Cinnamon

Save the file and close the editor.
To make the changes take effect, you must restart Cinnamon. Press Alt+F2, type r and press Enter.

Transparent system panel in Linux Mint 17.x Cinnamon

Now the system panel Cinnamon should be transparent.
Good luck!!!
