Trelby not installing in 16.04

Trying to install trelby by using sudo dpkg -i trelby_2.2_all.deb produces this error:

Selecting previously unselected package trelby.
(Reading database ... 267174 files and directories currently installed.)

It clearly looks like a dependency issue, but I don't know how to resolve this.

Any ideas?

Solution 1:

I had the same dependency problem with the .deb package on Ubuntu 17.04, but installing Trelby from source was fairly simple.

1. Install python-lxml and python-wxgtk3.0 from the repository:

   sudo apt install python-lxml python-wxgtk3.0
   

2. Download and extract the Zip file or clone the Git repository. Example:

   sudo apt install git
   git clone https://github.com/oskusalerma/trelby.git
   cd trelby
   

3. Navigate to the trelby folder and enter:

   sudo python setup.py install
   

   Done, you can now type, or add a shortcut pointing to, /opt/trelby/bin/trelby to start Trelby

Solution 2:

As written in this Debian mailing list:

It's a problem with Trelby: https://github.com/oskusalerma/trelby/commit/50c46f2249ca5b094c5e712a872e1dadbd8dfdfa

Looks like it was fixed, but no new package was built.

You might want to report a bug to the Trelby developer, and preferably ask them to list the requirements for the package too. "Ubuntu/Debian" doesn't tell you much.

You might also consider compiling it from source.
