It's not just ww.gutenberg.org. That's an example of what happens no matter what site I try to use wget on.  About the truststore, how do I add to or update it?  I decided to ask for help after trying to install openwebrx following the instructions here. https://www.openwebrx.de/download/ubuntu.php  Also I found out today that something similar happens with youtube-dl.  I tried to use it today and this is what happened.   Youtube-dl works if I use the --no-check-certificate option. $ youtube-dl https://www.youtube.com/watch?v=VW3XQDDGhA4 [youtube] VW3XQDDGhA4: Downloading webpage WARNING:Unable to download webpage: [youtube] VW3XQDDGhA4: Downloading API JSON ERROR:Unable to download API page: (caused by URLError(SSLCertVerifica tionError(1, '[SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed: unable to get local issuer certificate (_ssl.c:1131)'))) On 9/16/22 17:33, James Mcphee via PLUG-discuss wrote: > check out the verification of the cert chain.  it works for me with a > new build of 20.04, so it might be that you need to add or update your > truststore. > openssl s_client -connect www.gutenberg.org:443 > < /dev/null | openssl x509 -text -noout > > up there at the top, this is what it looks like when it works > depth=2 C = US, ST = New Jersey, L = Jersey City, O = The USERTRUST > Network, CN = USERTrust RSA Certification Authority > verify return:1 > depth=1 C = US, ST = VA, L = Herndon, O = Network Solutions L.L.C., CN > = Network Solutions OV Server CA 2 > verify return:1 > depth=0 C = US, ST = Utah, L = Salt Lake City, O = Project Gutenberg > Literary Archive Foundation, CN = *.gutenberg.org > verify return:1 > DONE > > I can see that i have that usertrust network cert in /etc/ssl/certs, > so all is good.  if i had to add one i'd have then run > update-ca-certicates. > > On Fri, Sep 16, 2022 at 2:17 PM Jim via PLUG-discuss > wrote: > > This has been bugging me for a while, but today it's annoying me > to the point I want to fix it.  Wget gives me an error whenever I > try to use it.  I have no problem getting files using a web > browser.  Here's an example.
