Problems downloading Python and Perl packages

Hi,
I should start by saying that I am very new to Slackware, this must my third or fourth day using it. I'm running Slackware 14.2 with spectrwm as interface.

I am having a strange problem, when I use sbopkg to download python or Perl files, the downloads stops with the following error message:

Resolving www.python.org (www.python.org)... 2a04:4e42:4::223, 151.101.16.223
Connecting to www.python.org (www.python.org)|2a04:4e42:4::223|:443... connected.
Unable to establish SSL connection.
This example was me trying to download python3, but the error is the same every time I try yo download from the Perl or Python site.

To add to this, when using firefox, I cannot open any pages from these sites. I click it and it does nothing. I can use firefox normally with any other site.

I imagine this has something to do with my ssl configurations, but unfortunately, I don't know anything about ssl, and what I read went over my head.

If anyone could help me with this, or just help me to understand what is happening, I would be much obliged.

Have you installed all the updates? How did you install spectrwm (since it isn't part of Slackware)?

I installed it through Slack Builds. As to the updates, even today I was lookin g for updates.

With updates, I think he is referring to Slackware's updates, which are located in the patches/ directory on your favorite mirror. There have been many SSL-based updates, including ca-certificates, which if it is out-of-date enough, it could prevent connecting to https sites without errors. Their certificate may be too new for the ca-certificates package on the system.

You shoudld also check that the date and time on your computer are set correctly.

Thanks bassmadrigal, I didnt kew about that. I am goig to that and get back with an answer

Ok, So I just installed most of the patches found in the mirror, making sure the openssl patches specifically,were installed, rebooted and the problem persists. Only now, when trying to open the python.org site, instead of not doing anything, it opens to a "about:blank" page.
I also checked my date and time and it was correct.

The ca-certificates update is probably more important than the openssl updates (in regards to connecting to websites, not in importance of updating). I would ensure you have upgraded all available patches.

That is what I ended up doing, I installed all of them just to be on the safe side. The problem remains.

Can you use wget to download something from python.org and see if it has the same error?

wget https://www.python.org/ftp/python/3.6.5/Python-3.6.5.tgz

If you are using firefox, you can turn on developer mode and see what information is returning from the http GET.

You could run

curl -v https://www.python.org | head

which should SSL and header information.

The problem persists with wget bassmadrigal, "unable to establish ssl connection".

As running firefox in developer mode, I will try a little later, for some reason I cannot open firefox now and can't reboot becausee I'm doing an install that is taking forever.

Bassmadrigal, I took your suggestion and run your instructions. This is the output

Are you sure you got the updates for 14.2 and not -current? This seems like it could be due to mismatched packages, but I'm not sure where to start. Maybe start with providing the output of the following:

ls -l /var/log/packages/openssh*
ls -l /var/log/packages/ca-certificates*
ls -l /var/log/packages/curl*

ls -l /var/log/packages/openssh*

You are using IPV6 to connect; my tests are using IPV4.

I don't know if IPV6 has been tested with Slackware 14-2; someone who has an IPV6 connection to the world may speak up.
