undefined symbol: sslv3_method

After tweaking this library to get past the non-existant python3 class of basestring, i've run into another issue.

Looks like this might be your issue? https://stackoverflow.com/questions/10547332/install-m2crypto-on-a-virtualenv-without-system-packages

It's a new issue with M2Crypto. In discussion w/ the author, I have a PR in to fix it:

https://gitlab.com/m2crypto/m2crypto/issues/189

I am curious why this library requires M2Crypto<=0.26.4. This would seem to preclude any bugfixes from being installed (such as the one mentioned in this ticket).

[dmknght]

I had same issue on my ubuntu server (virtualbox machine). I removed M2Crypto from pip and i installed python-m2crypto (apt-get). My issue solved.

[zgoda]

There is merge req that will solve this issue. Until it's merged & released we're limited to workarounds.

https://gitlab.com/m2crypto/m2crypto/merge_requests/194

[gamgi]

As the fix is now merged, this issue can be solved by pip install --upgrade M2Crypto

[fahhem]

What version is the PR in? I'll update setup.py to mention the correct version(s)

[zgoda]

It's in 0.30 milestone, current version in PyPI is 0.30.1

https://gitlab.com/m2crypto/m2crypto/milestones/13

EDIT:
Confirmed this goes away after updating M2Crypto to latest. Pip barks about incompatibility with adb requrement but AdbCommands instance seems to work as usual.
