Getting an obsolete package with apt-get

Are you using Trisquel 6 or Trisquel 7?

I'm pretty sure it either is or isn't in the repository. If a package is considered to be obsolete (e.g. ffmpeg), it stops being included in the repository, perhaps transitioning into something else at first (in the case of ffmpeg, avconv). If a program you want isn't in the repo, you'll have to install it from some other source.

I'm using Trisquel 7.

Presumably there's a way of telling apt-get which archive to use - it's easy enough to locate that archive, as Kompozer is alive and well in the hinterlands, just not in the current trisquel repository.

Here's what I've tried, so far without success:

"sudo add-app-repository http://oldarchive.trisquel.info/trisquel/pool/main/k/kompozer/"

That "took" OK, but subsequently, "sudo apt-get install kompozer" failed. Couldn't find the kompozer package.

Evidently, http://oldarchive.trisquel.info/trisquel/pool/main/k/kompozer/ isn't a repository, even though it's legitimately part of trisquel.info.

KompoZer is discontinued. It has not received any update in more than five years. I guess LibreOffice Writer now is a better WYSIWYG HTML editor.

If you insist on a Gecko-based editor, try BlueGriffon... which looks discontinued as well (no release in two years) but at least supports some HTML5, CSS3, etc.

Still stumbling around. I added the following lines to my /etc/apt/sources.list:

deb http://oldarchive.trisquel.info/trisquel/pool/main/k/kompozer/kompozer-data_0.8~b3.dfsg.1-0.1_all.deb kompozer main
deb http://oldarchive.trisquel.info/trisquel/pool/main/k/kompozer/kompozer_0.8~b3.dfsg.1-0.1ubuntu1_i386.deb kompozer main

With the following result when attempting sudo apt-get update:

> W: Failed to fetch http://oldarchive.trisquel.info/trisquel/pool/main/k/kompozer/kompozer-data_0.8~b3.dfsg.1-0.1_all.deb/dists/kompozer/main/binary-i386/Packages 404 Not Found

Magic Banana suggested:
> download http://oldarchive.trisquel.info/trisquel/pool/main/k/kompozer/kompozer-data_0.8~b3.dfsg.1-0.1_all.deb and http://oldarchive.trisquel.info/trisquel/pool/main/k/kompozer/kompozer_0.8~b3.dfsg.1-0.1ubuntu1_i386.deb and install them in the same order

Alas, once on my 'puter, I was faced with two choices [only]: "Extract" or "Open."

Extracting produced a directory structure, but with a penalty: "an error occurred." Alas, an unspecified error, it seems.
"Open" just opens the chosen directory ... looks a little like a mozilla product.

On a tangential path, I tried applying wine to netscape, but that produced a host of unwelcome warnings & error messages.

And I took a look at the Bluefish editor. Kinda like a carpenter with too many nails in his mouth. Harkens back to the TRS-80 'puter on which I learned to write technical reports: So many details to remember that the task at hand is forgotten.

When I cannot find a package in the repositories that I want to install I go to the Debian package search and look for that software as a debian package.

Here is KompoZer's: https://packages.debian.org/squeeze/kompozer

Once there I select a download that corresponds to my architecture. e.g. amd64 for me.

Once downloaded I open a terminal window and cd to the directory that I downloaded the .deb file to.

once there I run the command dpkg -i file.deb

That should get you where you need to be, unless there are dependencies you don't have.

Of course any dependencies you will have to track down either in the repositories or by getting the debian package for that particular dependency.

I hope this helps.

Success !

Magic Banana suggested (with appropriate local adjustment for my new Lenovo T420 laptop):
> download http://oldarchive.trisquel.info/trisquel/pool/main/k/kompozer/kompozer-data_0.8~b3.dfsg.1-0.1_all.deb and http://oldarchive.trisquel.info/trisquel/pool/main/k/kompozer/kompozer_0.8~b3.dfsg.1-0.1ubuntu1_amd64.deb and install them in the same order ...

Then grimlok piped up with:
> Once there I select a download that corresponds to my architecture. e.g. amd64 for me.
> Once downloaded I open a terminal window and cd to the directory that I downloaded the .deb file to.
> once there I run the command [sudo] dpkg -i file.deb

The combination worked just fine; I followed up with sudo apt-get update and sudo apt-get upgrade for good measure.

KomPozer is now in my Programming folder and opens without any hassle. Nice WYSIWYG for plain old html.

Thanks to all for your extraordinary patience.
