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

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.

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.  Using firefox I was able to download the file, but this can be a pain in the butt when I'm trying to add a repository.  I have Ubuntu 20.04 installed.

$ wget https://www.gutenberg.org/ebooks/68992.epub.images

Any idea how to fix this?  thanks
