Classic theme stopped working :( Topic is solved

[Octopuss]

Why did a minor update break a theme? Now the program looks horrible
Specifically, it's ClassicTB2 for Epyrus.

I have no idea. It's probably just because I bumped the middle version number of the mail client... I vaguely remember this happening the last time I went from 2.0.x to 2.1.x. Possibly the version in there just needs to be bumped? If I'd remembered that would happen I might have just gone for 2.1.4.

But in all honesty, I don't maintain the ClassicTB2 theme myself.

Either this isn't the fix or I don't know how to do the hack properly. For background, I've gotten it to work on like only one extension ever, so...

Check for updates in the Add-on manager of Epyrus! I've just released a theme update for it.
It should update to a compatible version, and then you need to re-enable it and issue a restart.

I must be especially stupid today but can you tell me how to do that? I don't see any check for updates button.
The theme is disabled and I can't do anything with it.
What am I supposed to do here?

edit: Nevermind, I simply removed it and went to the addons website and downloaded the .xpi again.
edit2: The theme works. Yay!

For future reference.

Add-ons manager -> gear -> check for updates.

Oh. Well that explains how I missed it with my ADHD. Tiny icon when your focus is stolen by the big fat coloured menu on the left, heh.

In Epyrus 2.2.0, legacy themes no longer work (at least the ones I have installed). Updating install.rdf like this makes them compatible again.

Code: Select all

<em:targetApplication>
		 <!-- Epyrus -->
            <Description>
                <em:id>{29877c1d-27df-4421-9a79-382c31470151}</em:id>
                <em:minVersion>2.0.0a1</em:minVersion>
                <em:maxVersion>2.2.*</em:maxVersion>
            </Description>
        </em:targetApplication>
    </Description>
</RDF>

I recommend you don't set maxversion to 2.* but keep it more conservative (e.g. 2.2.*)

That’s true, I fixed it in my post.

Okay but what are the next steps? Please post a URL for "how to distribute XPI files for UPX"; my link is missing or stale. The docs tell the correct way to ZIP the folder into an XPI file.

Extensions that have a folder under the browser profile could I guess be updated in place? But the real way to make this change is to package it properly for others to download and install.

I’m not sure if there’s an Epyrus add-on that can export themes. The simplest way is to re-download the theme from here:

Code: Select all

https://services.addons.thunderbird.net/en-US/thunderbird/complete-themes/

Open it with WinRAR, 7-Zip, or Ark (on Linux), edit

Code: Select all

install.rdf

in a text editor as mentioned above, and then install it again.

The answer I wanted is the "Command Line method" in this stack overflow answer. That gets me past the problem of 'cannot install upated xpi containing updated rdf'

Okay but what are the next steps?

simplest way:
- re-download the [xpi]
- Open it [in a ZIPper GUI]
- edit install.rdf
[- ensure the GUI updates the xpi with the changes]
[- close the GUI]
- install [the updated xpi]

Okay added the unstated part of these instructions This manual method is less consistent than a scripted solution.

Thanks so much - my Epyrus looks normal again!
