Unable to install latest brackets on Ubuntu 15.04

Update, the version below is not longer available. Now you have to install the Trusty version:

wget https://launchpad.net/~ubuntu-security-proposed/+archive/ubuntu/ppa/+build/7110687/+files/libgcrypt11_1.5.4-2ubuntu1.1_amd64.deb
sudo dpkg -i libgcrypt11_1.5.4-2ubuntu1.1_amd64.deb

The package libgcrypt11 isn't longer an installable package in Ubuntu 15.04. You need now the library libgcrypt20.

Therefore install the latest Utopic package from here with:

sudo dpkg -i libgcrypt11_1.5.4-2ubuntu1.1_amd64.deb

Or follow the steps from my previous answer to change the dependencies for the brackets package and use libgcrypt20.

All you have to do is install libgcrypt11 from an older Ubuntu version, such as Ubuntu 14.04 LTS:

https://launchpad.net/ubuntu/+archive/primary/+files/libgcrypt11_1.5.3-2ubuntu4.2_i386.deb

https://launchpad.net/ubuntu/+archive/primary/+files/libgcrypt11_1.5.3-2ubuntu4.2_amd64.deb

I had the same problem. After following the steps from A.B.'s answer, the error didn't go away. I installed Brackets from Ubuntu-After-install.

https://www.thefanclub.co.za/how-to/ubuntu-after-install

1. follow these steps:

sudo add-apt-repository ppa:thefanclub/ubuntu-after-install
sudo apt-get update
sudo apt-get install ubuntu-after-install

2. open ubuntu-after-install from your apps.
3. type-in your password.
4. Select Brackets from the list. It will probably be the last entry in the list and click install. You are ready to go.

You can install Brackets via PPA:

sudo add-apt-repository ppa:webupd8team/brackets
sudo apt-get update
sudo apt-get install brackets
