Script to install traditional Thunderbird

[Schwarzer Kater]

Good point jlittle. Changed it. Thanks for the suggestion, sometimes I am slow on the uptake…

I have tested the script with 24.10 and 25.04 during the past weeks and improved some minor code for KDE Plasma 6.

You updated the script to use tar xJf; I wonder why you don't just use tar xf. Then, tar works out what compression has been used. If the first version had used tar xf, the problem with the change of compression would not have occurred.

[Schwarzer Kater]

Recently I realized that Mozilla seems to have changed their compression methods from .bz2 to .xz - so the script did not work anymore.

I updated the script accordingly to version 1.0.3 and I deeply apologize for any inconvenience this bug may have caused for you!

Hi Schwarzer Kater,
for some unknown to me reason KDE neon since it's latest release sadly uses the Snap package for Thunderbird in contrast to Firefox for which it uses the official Mozilla PPA.
For that reason I decided to try this script, which I used successfully on Kubuntu before, on the current KDE neon release, which is 6.3 based on Ubuntu 24.04. Sadly it's not working but looking at the script I suspect it currently also does not on Kubuntu (?).
The errors shown by the script are relating to the extraction of the archive file:
------------------------------------------------------------------
bzip2: (stdin) is not a bzip2 file.
tar: Child returned status 2
tar: Error is not recoverable: exiting now
-> AN ERROR OCCURED! <-
This Thunderbird archive seems to be corrupt
------------------------------------------------------------------
It's the tar command in the script which fails.
The choice of language made no difference no matter which language I tried.

I then proceeded to remove the script's check for a successfull archive extraction and run it without that which went through successfully but naturally without Thunderbird being extracted and moved into /opt which I then did manually and made Thunderbird work. This shows that the archive itself isn't corrupt and can be successfully extracted via KDE's Ark.
I now wonder if the culprit is that Mozilla possibly just changed the download's filename or compression format or so since the difference I saw was that the script's Thunderbird downloaded showed up as a .tar.bz2-file while the file I manually downloaded via the link found within the script resulted in a tar.xz file. I fail to get the logic behind that since I copy/pasted the link directly from within the script so I expected the same filename for the download.

*EDIT* The issue is certainly not the filename-extension since I just edited the script to also use the .tar.xz extension but the extraction still failed. So maybe it's the compression format or whatever.

Anyway, maybe you can figure it out and possibly update the script unless it's unexpectedly an issue only on KDE neon.

Greets!

Question, is there a way to copy/move my profile from the snap version across to this version installed? I'm currently "de-snapping" myself as much as I possibly can. I can find the snap installed version. Do I just copy the folders that have the same name across?

[Schwarzer Kater]

Update to version 1.0.2:
better late than never - now all scripts test first if the computer has established an internet connection as this is needed.

[Schwarzer Kater]

Re-tested dozens of times with Kubuntu 24.04 LTS (development branch, Beta and final release): works.

[Schwarzer Kater]

The same additions as for the install traditional Firefox script:
Now the script can remove the traditional Thunderbird from /opt, if it has been installed by this script before.
Plain error handling for e.g. a bad connection or a missing particular language version has also been added…

[Schwarzer Kater]

Purpose of this script

This is a little helper script for Kubuntu™ (24.04 & later) users who want to install the traditional Thunderbird from Mozilla.org and use it complementary to or instead of the Thunderbird Snap.
It can also remove the traditional Thunderbird, if it has been installed by this script before, and has been tested many times with Kubuntu™ 24.04 LTS up to 25.04.

I hope you find the script useful! Yours respectfully, Schwarzer Kater

Installation and usage of this script

1. You can download the script from here: https://gitlab.com/scripts94/kubuntu...al-thunderbird
   Click on its name in the file list and on the next page use the download button on the far right side of the script name.
   OR
   Copy and paste the code of the script into a blank Kate text editor document and save it as "Kubuntu_install_traditional_Thunderbird.sh" to e.g. your home directory.
2. Make the file Kubuntu_install_traditional_Thunderbird.sh executable in the Dolphin file manager:
   go to the directory you downloaded/saved the script to, right-click on the file and choose Properties --> Permissions --> enable Is executable --> choose OK.
   OR
   Make the file Kubuntu_install_traditional_Thunderbird.sh executable in the Konsole terminal emulator:
   go to the directory you downloaded/saved the script to (cd [path to]/[name of directory], e.g. cd ~/Downloads) and enter:
   chmod +x Kubuntu_install_traditional_Thunderbird.sh.
3. To run the script in the Konsole terminal emulator go to the directory you downloaded/saved the script to and enter:
   ./Kubuntu_install_traditional_Thunderbird.sh

Important

• It is advised to run this script after a full upgrade of the system (either with Discover or in Konsole with sudo apt update && sudo apt full-upgrade) AND a reboot.

• Thunderbird from Mozilla.org can simply be used alternatively with or without the Thunderbird Snap and no further actions are to be taken.
  It will remain installed when release-upgrading (e.g. from 24.10 to 25.04) and causes no conflicts during the upgrade process.
  This version of Thunderbird behaves roughly like the ones for macOS™ or Windows™ do and updates itself independently from Discover or APT package management (and can ask you before updating - if you would prefer being asked see the Thunderbird settings).

You will be asked if you want [1] to download and install Thunderbird from Mozilla.org OR [2] to remove a previously installed Thunderbird, but if you choose [3] to cancel, no changes at all are made to your system.
After you chose [1] to install Thunderbird from Mozilla.org, you will be asked to select your preferred language next.

For some more information about what is done in detail see the comments within the script itself.

Known issues / bugs

• Don't start and use both the traditional Thunderbird and the Thunderbird Snap simultaneously - this can lead to problems!

• In very rare cases the compressed binary from Mozilla's server was either temporarily not available in a particular language or was corrupted (it once happened with "English (South African) lang=en-ZA" for example).
  The script will inform you about this and suggest the following solution.
  --> The solution is to run the script again, choosing a more "common" (but nonetheless fitting) language version like "English (US) lang=en-US" instead - which then has always worked fine.
  After the installation you can change to your preferred language in the Thunderbird settings.

Other Ubuntu™-based distributions

No other Ubuntu™-based distributions/flavours but Kubuntu™ 24.04 LTS & later are officially supported.

Due to the amount of time it would take to thoroughly test this script with other distributions/flavours I will probably also not support them in the future.

That said, the script should work with other official flavours of Ubuntu™ so far.
