Unable to Download Software

[Amarjit3]

I am attempting to download the software after following the instructions in the wiki. However, I receive the following error

$ sudo apt update
Ign:3 https://xpra.org focal InRelease
Err:5 https://xpra.org focal Release                                           
  Certificate verification failed: The certificate is NOT trusted. The certificate chain uses expired certificate.  Could not handshake: Error in the certificate verification. [IP: 78.129.163.65 443]

E: The repository 'https://xpra.org focal Release' does not have a Release file.
N: Updating from such a repository can't be done securely, and is therefore disabled by default.
N: See apt-secure(8) manpage for repository creation and user configuration details.

I am using Pop_OS! 20.04 - what is the issue?

Thanks in advance.

I assume that you're following these instructions: https://github.com/Xpra-org/xpra/wiki/Download#-for-debian-based-distributions

Is the date correct on your computer?

The certificate for https://xpra.org was clearly valid:

SSL Server Certificate
Common Name (CN)	xpra.org
Organisation (O)	<Not part of certificate>
Organisational Unit (OU)	<Not part of certificate>
Common Name (CN)	R3
Organisation (O)	Let's Encrypt
Organisational Unit (OU)	<Not part of certificate>
Issued On	Tuesday, 3 August 2021 at 19:36:01

SHA-1 Fingerprint	1E 78 7F B8 F3 3F B4 55 F6 80 FA 51 15 02 55 B8

In any case, I have renewed it one week early:

Yes I am using these instructions and my date is correct

Yes I am using these instructions and my date is correct

Then perhaps there's something wrong with your ca certificates. This should work:

wget https://xpra.org/gpg.asc

Hey @totaam I'm actually having the same issues. It complains that the key is not valid anymore (my system time is correct):

Err:6 https://xpra.org focal Release                            
  Certificate verification failed: The certificate is NOT trusted. The certificate chain uses expired certificate.  Could not handshake: Error in the certificate verification. [IP: 78.129.163.65 443]

And also it mentions that there is no release file:

E: The repository 'https://xpra.org focal Release' does not have a Release file.
N: Updating from such a repository can't be done securely, and is therefore disabled by default.
N: See apt-secure(8) manpage for repository creation and user configuration details.

These are the steps I'm following:

sudo apt-get update
sudo apt-get install apt-transport-https
wget -q https://xpra.org/gpg.asc
sudo apt-key add gpg.asc
# Everything works up to here!

sudo add-apt-repository "deb https://xpra.org/ focal main"
sudo apt-get update
sudo apt-get install xpra

Is this something that needs to be fixed on your end? Or is there something missing on my end? Can you tell from this?

@Amarjit3 were you able to fix it?

@totaam The problem lies with Ubuntu apparently. This is not the only project that has been affected from what I can tell. Take a look at this or this.

The solution is to update the ca-certificates package in Ubuntu. You can do this via sudo apt update && sudo apt install ca-certificates. After I did that, I could use the instructions without issues.

The problem lies with Ubuntu apparently.

Agreed. Nothing we can do about it here.
