what is a difference between Ubuntu and Debian

In the Linux world, there are lots of different distributions. For example, there are Arch, Debian, Red Hat, and many more.

Some distributions are derived from (or based on) other ones. We call this type of distribution a derivative.

For example, Fedora is a derivative of Red Hat. Ubuntu is a derivative of Debian. Mint is a derivative of Ubuntu. There are many more.

Some derivatives are very close to another, and we often call that type of distribution a flavour. For example, Lubuntu is a derivative of Ubuntu, but because it is so close to Ubuntu, we also call it a flavour of Ubuntu.

Each one is a distribution. So, Debian and Ubuntu are different distributions, even though Ubuntu is derived from Debian. Lubuntu and Ubuntu are different distributions, even though Lubuntu is a flavour of Ubuntu.

I hope that this helps!

An addendum and clarification of the above regarding support here and at AskUbuntu:

https://ubuntu.com/desktop/flavors

This are the only official derivatives supported. For any others (e.g. Linux Mint, an unofficial Ubuntu derivative often asked about but, again, unsupported) you can ask at Unix & Linux or, if available, the distro’s own forum.

As you probably know sometimes the issue we face it has not so easy solution. This is that case.

The new issue I have now is different. If you see this pdf file on European Court of Human Rights it can not be saved to offline view : https://www.echr.coe.int/d/application_form_nld

But after several attempts, I managed to get around it.

First open the document in the print window and only then save as a pdf file from that window.
Even if this is a step forward because you can already save the document, it does not solve the problem that you can not then edit it in such an interactive way as it opens in a web browser.
In the browser every field is available to fill in and modify.
When I save as above I can’t really do that.
I wonder if that is possible at all?

That website is designed poorly. When I click the download button, I get the downloaded file, but it’s just the error message that you mentioned.

You might want to contact the site’s technical team and raise a bug report.

Saving it by printing to PDF is pretty basic and now that you’ve done that you need to pick an editor which brings us back to your original thread from last November.

PDF EDITOR

Is there anything better then Only Office for Editing and modifing PDF documents on Linux? I need to modify and delete some parts of text in pdf document which with OnlyOffice is not so easy. I remember when I was still using Mac OS it was very easy to do such a thing.In here in Linux with the above app is really painful especially when I remember how easy it was with Mac Os.

Bro, listen to me. If you do heavy office work, I‘d recommend a Windows + Linux dual-boot setup.

Hello,

I was very curious when I came across this thread. So I tried the usual things for such a case just to test it:

1. open it using opera, (message as in OP appeared), saved it, couldn’t open it either using document viewer, xournal, gimp!

2. open it using firefox (now with no message, I was able to see the document), save it, yet ditto as above…

3. open it using firefox, print it to file and voila! The document as it should have been.

Thanks for that, because I didn’t know that if the need arises, this should be a handy solution.

I didn’t try papers though, since I have ubuntu 24.04.

Regards!
