Description Per Gunnarsson 2020-05-30 07:53:32 UTC
When I try to run electrum, I get:

/usr/local/bin/python3.7 /usr/local/bin/electrum
Traceback (most recent call last):
  File "/usr/local/bin/electrum", line 82, in <module>

@Per Thank you for your report. Couyld you please include additional information, including:

- Exact FreeBSD version (uname -a output)
- Whether you are using ports or packages, and if packages, what version (quarterly or latest)
- pkg version -v output (as an attachment)
- /etc/make.conf contents (if not empty)

The issue itself appears to be related to Python, rather than electrum itself, and can often occur when updating or changing SSL library versions, but not also rebuilding Python after that change

This should be reproducible without electrum by running:

$ python3.7
>>> import ssl

I use packakes, except for these port where I have changed make options:

Comment 4 Kubilay Kocak freebsd_committer freebsd_triage 2020-05-30 09:01:47 UTC
Thanks you for the additional information

The system does not have a SSL library built from ports, which means SSL functionality is provided by base, and I believe FreeBSD's base OpenSSL version recently changed, and has on a couple of occasions in the recent past.

When running non-RELEASE FreeBSD versions, part of the support and management process is to rebuild dependent subsystems (in this case Python and/or other SSL consuming softwares), when the underlying base system ABI changes. This appears to be one of those cases.

Since you're also using packages, and unless you're creating or using your own package sets built on or from the *same base revision* as the consuming system (13-CURRENT), this means that those packages will require (be built against) the OpenSSL version that the package building servers have, which may not match your systems.

This is very likely the cause of this issue.

Rebuilding Python and any other software that depends on OpenSSL from base, from ports, should resolve the issue.

Thanks for quick help and advice!

I made python3.7 from ports and now electrum seems top work just fine, both the version in ports and the version I downloaded from the Electrum web page.

Thank you for the feedback, I am glad it worked.

May I close this PR as resolved?
