RSS feeds don't work

I’m getting the following error when trying to add to my feed reader:

60 SSL certificate problem: unable to get local issuer certificate

I have other discourse sites in my feed reader which work fine:

  • ://
  • ://
  • ://

I followed these recommendations in the past for such errors but in this case it rather seems like an issue with the site configuration.

I have no problems with curl for the other URLs from a clean artful VM. Using and testing the answer from StackOverflow on my computer running 16.04 gives me the following:

$ curl --cacert /etc/ssl/cacert.pem
curl: (60) server certificate verification failed. CAfile: /etc/ssl/cacert.pem CRLfile: none
More details here:

curl performs SSL certificate verification by default, using a "bundle"
 of Certificate Authority (CA) public keys (CA certs). If the default
 bundle file isn't adequate, you can specify an alternate file
 using the --cacert option.
If this HTTPS server uses a certificate signed by a CA represented in
 the bundle, the certificate verification probably failed due to a
 problem with the certificate (it might be expired, or the name might
 not match the domain name in the URL).
If you'd like to turn off curl's verification of the certificate, use
 the -k (or --insecure) option.

Since I’m a new user I can only post 2 http(s) links, so replace :// with https:// please.

Strange. I just tried installing Liferea on Ubuntu 16.04 and it works fine here.

However, running it through an SSL checker was a bit interesting:-

Checking with our IS people.

Looks like @deej has fixed this…

<p>We are pleased to announce that Mir 0.28 has been released and is available in Ubuntu 17.10 (Artful).</p>
<p>As the content (and even the name) of this release has changed over the time we’ve been working towards it now is probably a good time to reflect on what it is, and what it isn’t after all.</p>
<h2>What is in Mir 0.28?</h2>
<h3>There is now a stable server ABI</h3>
<p>This simplifies the use of “Mir snaps” making it possible to release new library versions without breaking servers.</p>
<p>One of the barriers to the adoption of Mir has been the potential for Mir releases to break downstream projects that depend on a stable ABI. This is provided by libmiral, which is now part of Mir.</p>
<p>The Yunit project which uses Mir as part of its graphics stack has already <a href="" rel="nofollow noopener">started migrating code</a> to use <code>libmir
al</code> for this reason.</p>

I confirm, it works here to with curl and my feed reader. Many thanks for the quick response and solution!


works for me (also liferea on 16.04)
but thanks for post, it hadn’t occurred to me to add this to my reader :slight_smile:
