Packages that do not appear in the Synaptic package manager

Atlante · 2025-11-23 21:38:06

Hello everyone. Sorry to bother you again. I installed Devuan 6 “Excalibur” by downloading the ISO image to a USB drive. Of course, I used the Xfce desktop environment. In the final stage of the installation, the installer says “Configuring libc6-dev.”

The installation went well, and the operating system boots without any problems. Then I go to the Synaptic Package Manager and get a warning indicating that there are broken packages. The broken package is libc6-dev. I go to “Filters,” “Broken,” and “Edit,” and it removes the libc6-dev package.

I'm trying to install gufw, gcalculator, and the graphical package manager... and I can't find them in the Synaptic package manager. I'm trying to install them from the terminal (sudo apt install "package name")... and it seems the repositories don't exist.

What did I do wrong? Why does libc6-dev break when installing the operating system? Why did these packages disappear from the Synaptic package manager if they were in Devuan 5 "Dadaelus"? How can I access these packages to install them?

Thank you very much in advance. Please excuse any syntax errors; I speak Spanish and I'm using a translator.

I generally find the GUI package mangers are not the best for the task. The command line usually works the best. The first thing to do when having problems is use the policy command to see what is says about the packages.

Generalmente, considero que los administradores de paquetes de la interfaz gráfica no son los más adecuados para esta tarea. La línea de comandos suele ser la mejor opción. Lo primero que hay que hacer ante problemas es usar el comando de política para ver qué dice sobre los paquetes.

root@9600k:~# apt policy gufw gcalculator
gufw:
  Installed: (none)
  Candidate: 24.04.0-3
  Version table:
     24.04.0-3 990
        990 http://gnlug.org/pub/devuan/merged excalibur/main amd64 Packages
Notice: Unable to locate package gcalculator

There you can see the gufw is available to be installed while the gcalculator is nowhere to be found. And a search on the package website shows it has never existed in Debian. Are you sure of the name of the package?

Allí puedes ver que gufw está disponible para su instalación, mientras que gcalculator no se encuentra. Una búsqueda en el sitio web del paquete muestra que nunca ha existido en Debian. ¿Estás seguro del nombre del paquete?

The libc6-dev package it appears would install properly here.

Al parecer, el paquete libc6-dev se instalaría correctamente aquí.

Perhaps a apt remove --purge libc6-dev to remove everything then an apt install libc6-dev to see if the error can be reproduced and show here for us to try and help with it would be the idea. I have used a translator to give replies in Spanish for you.

Quizás una buena idea sería usar apt remove --purge libc6-dev para eliminar todo y luego apt install libc6-dev para ver si se puede reproducir el error y mostrarlo aquí para que podamos intentar solucionarlo. He usado un traductor para ofrecerte las respuestas en español.

Whenever you see broken packages, it's a good idea to try apt-get -f install to see if apt can fix the problems for you. It doesn't always work, but it is worth trying. libc6-dev might be important. For example, I need it to install my WiFi drivers. This makes me wonder if you are having connection issues. Are you able to install any packages at all? What error message are you seeing when you enter apt install synaptic?

For my Daedalus installation aptitude says this:

$ aptitude why libc6-dev
i   build-essential  Depends g++ (>= 4:10.2)
i A g++              Depends g++-12 (>= 12.2.0-1~)
i A g++-12           Depends libstdc++-12-dev (= 12.2.0-14+deb12u1)
i A libstdc++-12-dev Depends libc6-dev (>= 2.23-1~)
$

But then I also see this:

$ aptitude why build-essential
i   udiskie               Recommends gobject-introspection
i A gobject-introspection Depends    build-essential
$

And this:

$ aptitude why udiskie
Manually installed, current version 2.4.2-1, priority optional
No dependencies require to install udiskie
$

From what I have read (just now) udiskie is a daemon for automounting USB drives, CD-Rs and such.
https://github.com/coldfix/udiskie?tab=readme-ov-file

udiskie gets started on login (?):

$ ps aux | grep udiskie
groucho  19075  0.0  0.0   3332  1568 pts/0    S+   10:06   0:00 grep --color=always udiskie
$

No idea as to why I have it as manually installed.

If I understand all of the above correctly (?) ...

Installing udiskie dragged in gobject-introspection as a recommends.
As a result, gobject-introspection dragged in build-essential as a dependency.
And then build-essential dragged in all these as dependencies:

build-essential Depends g++ (>= 4:10.2)
g++ Depends g++-12 (>= 12.2.0-1~)
g++-12 Depends libstdc++-12-dev (= 12.2.0-14+deb12u1)
libstdc++-12-dev Depends libc6-dev (>= 2.23-1~)

TL;DR
It would seem that libc6-dev has been installed in my Daedalus system because whoever wrote udiskie thought that it was a good idea to put in gobject-introspection as a recommends.

Not too sure that I got it right so I'd appreciate some input on this.
Edit: maybe a good number of other packages depend on libc6-dev being installed.

Best,

A.

gcalculator is probably a typo, the correct name is galculator without the 'c' after the initial 'g'.

Okay. Thanks to everyone for your replies.

Replying to RedGreen925:

Thanks for your help.

I ran the command `apt remove --purge libc6-dev` and the terminal response was “Unable to locate package libc6-dev”.

Then I ran the command `apt install libc6-dev` and the terminal response was “Unable to locate package libc6-dev”.

I ran the command (as root) `apt policy ufw` and the terminal response was “Unable to locate package ufw”. Regarding “gcalculator”, it was a typo on my part. Tux_99 kindly and accurately corrected me below; the correct package name is the one he wrote, “galculator”. I had the same result as with ufw.

I ran the command (as root user) apt install -s libc6-dev and the terminal response was “Could not locate package libc6-dev”.

I tried installing other packages I also use, like Thunderbird and Mirage. In the case of Thunderbird, the terminal's response was, "The package thunderbird could not be located. The package thunderbird is unavailable, but some other package references it. This may mean that the package is missing, obsolete, or only available from some other source."

In the case of Mirage, it was the familiar response, "The package mirage could not be located." Best regards.

Reply to Stultumanto:

Thanks for your help.

I ran the command `apt-get -f install` and the terminal response was “Reading package lists . . . Done. Building dependency tree . . . Done. Reading state information... Done
0 upgraded, 0 new packages to be installed, 0 to remove, and 0 not upgraded.”

I have no connection problems whatsoever. I connect to the internet and the web quickly and perfectly. I can't install anything, Mr. Stultumanto. If you read my reply to RedGreen925, you'll see that I can't install anything.

The terminal output after running the command `apt install synaptic` was: “Synaptic is already up to date (0.91.7).
Set Synaptic as manually installed.
Summary:

Upgrading: 0, Installing: 0, Removing: 0, Not Upgrading: 0”. Best regards.

Thanks for your help.

I had absolutely no problems with version 5, "Dadaelus." These problems are with version 6, "Excalibur." Best regards.

Reply to Tux_99:

Thanks for your help.

Yes, that's right. I made a mistake. The correct name is the one you mentioned, "galculator." Best regards.

Hi, RedGreen925

Okay. I ran the recommended command and the result was: “No such file or directory.” I don't know what to think. It seems to be a structural problem. Perhaps I selected the wrong ISO image that I downloaded and copied to a USB drive (I used the `dd` command with the parameter `status=progress` and everything went well; the ISO image was copied completely without problems), and that USB drive was formatted with the command `udo mkfs.vfat /dev/"USB drive"`. That's how I did it when I installed version 5 “Dadaelus.” Maybe I should use the command `mkfs.ext4 /dev/"USB drive"`, I don't know. Looking through the installation, besides the terminal being practically unusable, I see that LibreOffice doesn't allow me to switch from English to Spanish, and I can't run the language conversion command for the same reasons I already mentioned. Perhaps I have to do a

I reinstalled the operating system, but before coming to this forum, I performed at least three reinstalls (I always try to exhaust all other options before coming to the forum; I know there's a lot of work involved here, it's volunteer work, and that deserves a lot of respect). It seems like a structural problem; the operating system shouldn't be practically frozen.

Here's the output from the terminal after running the recommended command:

$ cat /etc/apt/sources.list. d/devuan.sources
cat: /etc/apt/sources.list.: No such file or directory
cat: d/devuan.sources: No such file or directory

Thank you for writing to me in my language and for all the help you're giving me. I really appreciate it.

greenjeans · Today 19:52:56

Don't know about the libc6-dev package or what happened there, but just at first glance from reading the rest of it indicates that the OP's machine is having the infamous dns issues with deb.devuan.org and apt is therefore not getting updated.

Probably need to edit /etc/apt/sources.list and try a repo from the list.

g4sra · Today 19:58:33

@greenjeans
Possibly the install barfed leaving sources.list as the default during install.

apt-get update will

1) prove networking is properly configured (IP,DHCP,DNS, blah,blah)
2) what is in sources.list (maslformed or excalibur, updates, security, blah,blah)
3) that the gpg keys are working correctly.

Non english speaker and linux newbie, instructions need to be phrased simply and carefully.
