Using this overlay

Add the URL to the /etc/layman/layman.cfg file:

https://raw.github.com/ormorph/TDE/master/layman/tde.overlay

It should look something like this:

overlays  :
    https://api.gentoo.org/overlays/repositories.xml
    https://raw.github.com/ormorph/TDE/master/layman/tde.overlay

Next, run the command:

# layman --fetch

After that the command:

# layman -L

the command must show the presence of the TDE overlay.

Next, set the overlay with the command:

# layman -a TDE

Next, determine the version of TDE to install. There are several files in the /var/lib/layman/TDE/package.keywords directory:

• the tde-14.0.7 file corresponds to TDE version 14.0.7;
• the tde-14.0.999 file corresponds to TDE version 14.0.x;
• the tde-999 file corresponds to TDE version 14.1.x, master branch;

Warning: the new version of portage uses the /etc/portage/package.accept_keywords directory instead of the /etc/portage/package.keywords directory.

Select the required version and create a symbolic link to the file corresponding to the selected version:

# cd /etc/portage/package.keywords
# ln -sf /var/lib/layman/TDE/package.keywords/tde-14.0.7

Select the language to install, for this, use the L10N variable in the /etc/portage/make.conf file:

L10N="de en"

For a minimal installation, run the command:

# emerge -av tde-minimal

For a basic installation, run the command:

# emerge -av tde-base

PS: It is currently recommended to use the official Trinity Desktop repository.
