Created attachment 1307390 [details]
Certificate information returned by Firefox for https://arxiv.org

Description of problem:
Any attempt to connect to https://arxiv.org fails when verifying the certificate's issuer:

$ lftp https://arxiv.org
cd: Fatal error: Certificate verification: Not trusted: no issuer was found (C4:3F:D4:BD:3C:BA:B7:8C:45:B1:6B:87:3B:C0:7B:A4:CF:32:99:A2) 

Version-Release number of selected component (if applicable):
lftp-4.7.7-1.fc26

How reproducible:
Always

Steps to Reproduce:
1. Run 'lftp https://arxiv.org'.

Actual results:
Attempt to connect fails with the error message: "Fatal error: Certificate verification: Not trusted: no issuer was found (C4:3F:D4:BD:3C:BA:B7:8C:45:B1:6B:87:3B:C0:7B:A4:CF:32:99:A2)".

Expected results:
Connection is established successfully.

Additional info:
- The same site can be accessed successfully with Firefox, and the related connection information does not reveal any issue (see attached screenshot).
- The issue appeared sometime during the last months.

Comment 1 Joachim Frieben 2017-08-01 07:10:25 UTC
No improvement after upgrading to lftp-4.8.0-1.fc26.

Comment 2 Michal Ruprich 2017-11-14 09:26:05 UTC
It seems that the problem is caused by a missing certificate in the chain of certificates returned by gnutls function in lftp (at least according to the upstream). I tried to look into the problem and suggested some ideas to the upstream.

Comment 3 Fedora End Of Life 2018-05-03 08:28:58 UTC
This message is a reminder that Fedora 26 is nearing its end of life.
Approximately 4 (four) weeks from now Fedora will stop maintaining
and issuing updates for Fedora 26. It is Fedora's policy to close all
bug reports from releases that are no longer maintained. At that time
this bug will be closed as EOL if it remains open with a Fedora  'version'
of '26'.

Package Maintainer: If you wish for this bug to remain open because you
plan to fix it in a currently maintained version, simply change the 'version'
to a later Fedora version.

Thank you for reporting this issue and we are sorry that we were not
able to fix it before Fedora 26 is end of life. If you would still like
to see this bug fixed and are able to reproduce it against a later version
of Fedora, you are encouraged  change the 'version' to a later Fedora
version prior this bug is closed as described in the policy above.

Although we aim to fix as many bugs as possible during every release's
lifetime, sometimes those efforts are overtaken by events. Often a
more recent Fedora release includes newer upstream software that fixes
bugs or makes them obsolete.

Comment 5 Ben Cotton 2018-11-30 21:34:47 UTC
Fedora 27 changed to end-of-life (EOL) status on 2018-11-30. Fedora 27 is
no longer maintained, which means that it will not receive any further
security or bug fix updates. As a result we are closing this bug.

If you can reproduce this bug against a currently maintained version of
Fedora please feel free to reopen this bug against that version. If you
are unable to reopen this bug, please file a new report against the
current release. If you experience problems, please add a comment to this
bug.

Thank you for reporting this bug and we are sorry it could not be fixed.
