Could you tell me whether this is output is given by maintenance in the repositories or is it that i am using something wrong in my sources.list (By the way i used this line at sources.list since the beginning of time, and it never showed problems).

Code: Select all

deb https://dl.winehq.org/wine-builds/ubuntu xenial main

If you could help me, thanks in advance!!

The repository is up and accessible; I have no problem browsing and downloading via Firefox. As to the error message from apt-get, I noticed that dl.winehq.org is the only repository on your system that uses https://, and googling found https://unix.stackexchange.com/question ... n-apt-tool.

Thanks for your answer!!
However, I neither have problems accessing the repo via browser. And, as it seems to suggest the link you sent, in Ubuntu, one needs to install the apt-transport-https, package in order to read correctly the repo, which I have correctly installed (after a quick check on synaptic). It seems that all the keys are correctly installed as well.
In order to increase the mystery, a week ago or so, I refreshed manually the repo via apt-get update, and i had the same result. However, after dozens of attempts executing apt-get updare, the package list sent no warnings. After being happy for 1 or 2 minutes, I updated it once more, and all the warnings came up once more... Today, the problem persists.

Looks like you followed the instructions for Linux Mint. That's not correct for Ubuntu.

From https://wiki.winehq.org/Ubuntu:

Add the repository:

Code: Select all

wget -nc https://dl.winehq.org/wine-builds/Release.key
sudo apt-key add Release.key
sudo apt-add-repository https://dl.winehq.org/wine-builds/ubuntu/

Hello Again!!
Thx for your answer, however I've been very busy during these days so I could read your answer just today!! Unfortunately, the repo keeps without being updated properly. I followed your instrucions after removing the original repo from my sources.list. However I still have some doubts about the answer. First, This what i wrote a while ago:

Code: Select all

deb https://dl.winehq.org/wine-builds/ubuntu xenial main

Nevertheless, your said:

Looks like you followed the instructions for Linux Mint. That's not correct for Ubuntu.

Ok you say that I should input the command

Code: Select all

...
sudo apt-add-repository https://dl.winehq.org/wine-builds/ubuntu/

And this last line adds exactly the same line I mentioned above plus a commented line (now I am sending the line apt added to my sources.list) (Ok, it has an extra "/" at the end of the address):

Code: Select all

deb https://dl.winehq.org/wine-builds/ubuntu/ xenial main
# deb-src https://dl.winehq.org/wine-builds/ubuntu/ xenial main

Despite I followed the instructions, the output for apt-get update keeps sending me the same error

What did I do wrong if I followed your instructions? Is there any other way to add the repository?
Thx in advance!!

Do you by any chance use a proxy?

And what is the result of :

Code: Select all

host -v dl.winehq.org
