Tails 7.8 Are there any reports of problems with Thunderbird install on 
v7.8, it was all working fine. It does finally install but throws errors 
which I suspect are nonsense, and the removal and reliance on additional 
software install on 7.7 is causing the problem.

You are spot on with your suspicion. Your gut instinct about the 
"removal and reliance on additional software install" is exactly what is 
driving this behaviour, and the errors you are seeing are indeed mostly 
noise caused by a major architectural change.

Here is the breakdown of what is actually happening behind the scenes in 
Tails 7.8 (released May 21, 2026), and why it is throwing those messy 
errors.

The Cause: Thunderbird Was Culled from the Base Image

Starting with Tails 7.8, the development team completely removed 
Thunderbird from the default, built-in system image.

The reason they did this is because Thunderbird releases updates 
following the Firefox calendar. Historically, this meant the built-in 
version of Thunderbird on Tails was almost always outdated and plagued 
with known security flaws for weeks at a time until the next complete 
Tails OS release caught up.

To fix this security vulnerability gap, Tails now handles Thunderbird 
via Additional Software and Persistent Storage.

Why You Are Seeing Errors (The "Nonsense" Flashing)

Because it is no longer built directly into the operating system's firmware:

     The Cold-Download Lag: Every single time you boot Tails 7.8, the 
system has to pull the latest Debian package of Thunderbird and install 
it onto the live AMNESIC layer from your Persistent Storage archive.

     The Dependency Hiccup: Because it's being installed as "Additional 
Software" automatically at startup, the system triggers the standard 
Debian package manager tracking hooks.

     The Race Condition: The desktop UI often loads faster than the 
background Additional Software script finishes compiling and verifying 
the configuration files. This "race" triggers false-alarm notifications 
claiming the installation failed, timed out, or threw broken package 
errors—even though a few moments later, the application mounts perfectly 
and opens just fine.

How to Clean Up the Installation & Quiet the Errors

If it is functioning but throwing annoying warnings at startup, you can 
force-reset the sync state between your Persistent Storage and the new 
Tails 7.8 automated system hook.

Try running a clean re-cache using these steps:
Verify your Persistent Storage Settings

Desktop Menu

Go to Applications > Tails > Persistent Storage. Ensure that both the 
Thunderbird Email Client and Additional Software switches are toggled ON.

Purge the old package cache
Terminal (Requires Root)
If your old upgrade configuration from Tails 7.7 is conflicting, open a 
root terminal and run a manual sync check to clear out the error state:

Bash
sudo apt update

(Note: This syncs over the Tor network, so it may take a minute or two).

Let Tails rebuild the automated hook

Final Step
If prompted by the desktop notification that Additional Software 
configuration has changed, click Install Every Time. Reboot your Tails 
device normally.

Once the initial index is cleanly cached onto your persistent volume 
under the new 7.8 framework, those false "installation failed" warning 
strings should settle down on subsequent boots.
