Ann: my LyX PPA for Ubuntu

[Guillaume Munch-Maccagnoni]

Bonjour,

This message concerns people who are using a Linux distribution based on 
Debian (such as Ubuntu), and who used to keep their LyX version up to 
date thanks to the official package archive.

Because the official archive is no longer updated, I have updated my own 
package archive to provide up-to-date LyX 2.5 to my colleagues. The 
package archive and the instructions to install the packages are 
available here: <https://launchpad.net/~gadmm/+archive/ubuntu/lyx-unstable>.

The following Ubuntu releases are currently supported:

* 22.04 LTS
* 24.04 LTS
* 25.10
* 26.04 LTS
* 26.10

Other Debian-based distributions are also supported by selecting the 
closest Ubuntu version.

These packages adjust the Qt "platform" and theme to better match the 
Ubuntu and Gnome desktops. (The change is not merely cosmetic: this 
should fix some bugs, as currently discussed on the bug tracker.)

Let me know how it goes for you if you use them.

Development versions of LyX 2.5 and 2.6 are also provided in addition to 
the latest stable release (these packages are compiled in debug mode).

The packaging scripts are available publicly, so I am hoping that this 
effort can also help restarting the updates to the official package archive.

Cheers,

Guillaume
