Setup Ubuntu Universe and Multiverse repositories

As root (e.g. using sudo), uncomment (remove the # marks from) the lines of your /etc/apt/sources.list file that include Universe and Multiverse

If your system does not contain entries for Universe and Multiverse, append "universe multiverse" to your main Ubuntu repository line.

Alternatively, you may use graphical tools or other tutorials to enable the Universe and Multiverse repositories.

Setup Ubuntu Recommended Updates repository

As root (e.g. using sudo), uncomment (remove the # marks from) the lines of your /etc/apt/sources.list file that include -updates.

If your system does not contain entries for -updates, copy your main Ubuntu repository line to the end of the /etc/apt/sources.list file and append -updates to the distribution name.

Alternatively, you may use graphical tools or other tutorials to enable the Recommended Updates repository.

Configure the package manager

Add the following lines to your /etc/apt/sources.list file.

Warning!

Make sure to replace <your-distribution-release-name> with your actual distribution release name (for example 'bullseye' or 'buster')

Import GPG signing key

The best way to install GPG key is to manually download and install package trinity-keyring. The advantage is that this method of installation is not dependent on the availability of the key server. Another advantage is that the key is not integrated into the global apt keyring, but is installed as a separate file:

$ wget http://mirror.ppa.trinitydesktop.org/trinity/deb/trinity-keyring.deb
$ sudo dpkg -i trinity-keyring.deb

Install Trinity

• If you are doing a fresh TDE installation, please follow the steps listed below.
  
• If you are upgrading from an existing version, please follow the instruction under the upgrading section.
  

Fresh installation

The following steps are suggested for installing the latest version.

Warning!

tde-trinity package is a comprehensive meta-package. To install only a basic environment, replace tde-trinity with tdebase-trinity in the instructions below.

$ sudo apt-get update
$ sudo aptitude install kubuntu-default-settings-trinity kubuntu-desktop-trinity

Localization

Tip

After installing the environment, it is also a good idea to install the localization packages so that you can switch the environment to your native language. For example, for Czech you would run:

$ sudo apt-get install tde-i18n-cs-trinity

Upgrading from an existing installation

The following steps are suggested for upgrading to the latest version.

Tip

Before upgrading from v3.5.13.x (or even KDE3), please make sure to go through this page for useful tips suggested by other TDE users.

$ sudo apt-get update
$ sudo aptitude full-upgrade

This will upgrade TDE to the newer version and should complete smoothly.

If you are upgrading from an existing R14.0.x installation, you are done.

If you are upgrading from v3.5.13.x, after these two steps some dummy packages may still be installed on your system and could be safely removed.

A. If you had previously installed some kde meta packages, (such as kde-core-trinity, kdeadmin-trinity, ...) use the command below, where <tde-equivalent-metapackage> is the equivalent package in R14.0.x (tde-core-trinity, tdeadmin-trinity, ...). Repeat for all meta packages there had been installed.

$ sudo aptitude install <tde-equivalent-metapackage>

B. Run aptitude in interactive mode, limit the display to ~i-trinity~ddummy and manually check/delete/upgrade unneeded packages from the ones displayed.

Upgrading both Ubuntu and TDE from a previous version

Warning!

Using a live CD to upgrade both Ubuntu and your Trinity installation may break your installation.
Instead, please follow these instructions.

1) Make sure you have update manager installed.

$ sudo apt-get install update-manager

2) Run the update-manager through console. Open a terminal and run:

$ update-manager

3) Check for updates and install all updates before proceeding. You need to have the latest packages to proceed.

4) Run the distribution upgrade tool. Click the upgrade button. Read the release notes, then let it download the upgrade tool. Authenticate with your password and let the upgrade run.

5) If you are upgrading from KDE 3 or TDE 3.5.x series, on the verification screens make sure there are no kde* packages anymore (for example, kdebase-kde3, kdelibs-kde3, kdebase-trinity, kdelibs-trinity).

6) You can allow the upgrade tool to check for obsolete packages. It should not remove TDE related ones.

Removing Trinity

Note

Please read the following instructions completely before starting the removal process.

Removing the Trinity Desktop Environment involves the following four steps:

1. Uninstalling packages
2. Removing the Trinity repository from the list of available package sources
3. Cleaning up the package cache
4. Removing left-over files from your home directory

Uninstalling packages

Using aptitude

If you have aptitude installed, you can simply run

$ sudo aptitude purge '~i~Otrinitydesktop'

Using apt-get

Using the standard apt-get utility to uninstall TDE and its dependencies involves the following three steps:

1. Generating a list of all packages available from the Trinity repository
2. Using that list to uninstall all installed packages originating from that repository
3. Uninstalling all packages that were installed as dependencies of Trinity

To generate a list of all packages available from the Trinity repository, you will need to filter out just the package names from two files in /var/lib/apt/lists and write the result to a new file. The names of these files depend on three factors: The Ubuntu release in use, the processor type the system is running on, and whether you're using the stable series or rolling-release packages. So, for example, when running the R14.1.x series on the i386 variant of Ubuntu Lunar, the names are as follows:

• mirror.ppa.trinitydesktop.org_trinity_deb_trinity-r14.1.x_dists_lunar_main_binary-i386_Packages
• mirror.ppa.trinitydesktop.org_trinity_deb_trinity-builddeps-r14.1.x_dists_lunar_main_binary-i386_Packages

First, let's create a new empty file in /tmp, using mktemp:

$ mktemp /tmp/tde.XXXX
/tmp/tde.fB6B

Generating a list of all Trinity packages and writing it to that file now works as follows:

$ sed -n '/^Package: / s/^Package: //p' /var/lib/apt/lists/mirror.ppa.trinitydesktop.org_trinity_deb_trinity-*Packages > /tmp/tde.fB6B

Be sure to replace the output file's name with the actual name of the file mktemp created on your system.

Now that we have a list of all TDE packages, we can hand that to apt-get for uninstallation:

$ sudo apt-get remove $(cat /tmp/tde.fB6B)

Replace apt-get remove with apt-get purge to also remove the configuration files that came with those packages. And, as above, be sure to replace the output file's name with the actual name of the file mktemp created on your system.

Apt will figure out which of the packages in the list are actually installed and present them for uninstallation. It will also already notify the user of a bunch of packages that "were automatically installed and are not longer required" and suggest using apt autoremove to uninstall them. We will take care of that in the next step. So, for now, just confirm the uninstallation of the TDE packages.

If Apt asks whether to stop the tdm deamon, say yes. We're removing TDE, after all. This will land you on the TTY that TDM was running on before. Need to switch back to the one you ran apt-get from using Ctrl + F1..7.

Finally, to uninstall all remaining Trinity dependencies, you will need to run

$ sudo apt-get autoremove

In case you also want to remove the configuration files that came with these packages, append --purge to the autoremove command.

CAUTION

Beware that running apt-get autoremove without care can leave certain software on your system or the system as a whole in an unusable state. The command simply uninstalls all packages that were installed as dependencies of packages that are no longer installed, which might lead to the uninstallation of packages that you wanted to keep.

Be sure to read the list of packages that Apt will want to uninstall, carefully. If you want to continue to use any of the packages in that list, abort the operation, mark that package as manually installed, and then run the command again.

If you're not sure how to handle the situation, ask in the Trinity IRC channel or on the mailing list.

Removing the Trinity repository from package sources

Open /etc/apt/sources.list and either remove the Trinity repository lines or comment them by adding a hash symbol (#) at the beginning of each line. Then save the file and run sudo apt-get update.

Cleaning up the package cache

If you deactivated/removed the repo from source.list, at least run

$ sudo apt-get autoclean

This will remove all Trinity packages from the local cache.

To get rid of other packages as well, you'll have to clean out the whole package cache using

$ sudo apt-get clean

Removing left-over files from your home directory

Remove TDE files in $HOME. Usually these are the .tderc file and the .trinity and .qt directories. (The latter is still mistakenly used by some applications.)
