I believe the issue stems from a breaking change in 2.1.0, specifically 'libtorrent minimum requirement increased (>= 1.2)'. I) was on Deluge version 2.x previously. Not entirely sure which one however. I'm not quite understanding what to do to fix this as everything is fully up to date. If anyone has some direction I would be grateful.

[mhertz]

What version of libtorrent, e.g 'deluged -V'.

Since you use deluge 2.1.1, then sounds like you're using a PPA or something, which includes newer libtorrent 1.2.x. That error also isn't seemingly related to using libtorrent 1.1.x.

There where an error reported regarding libtorrent 1.2.x on ubuntu 18.04, which I reproduced and posted various workarounds, though best workaround later came from yufaazhi here: viewtopic.php?p=235002#p235002 (Bottom part, so cd into dir and make a symbolic link from original name to libtorrent.so, e.g I posted relevant line in another thread with same subject, though just changed link to be in /usr/local instead, as more appropriate imho, but can be changed back fine also:

Code: Select all

sudo ln -s /usr/lib/python3/dist-packages/libtorrent.cpython-36dm-x86_64-linux-gnu.so /usr/local/lib/python3.6/dist-packages/libtorrent.so

Note, change/remove the x86_64 part of filename, if on 32 bit.

Granted the error from that ubuntu 18.04 issue was different, but just sounds related still somewhat, as libtorrent 1.1.x surely has a __version __ attribute also.

If not using the PPA, then imho consider to(for newer libtorrent 1.2.x) , and if needed, above fix afterwards.

https://launchpad.net/~deluge-team/+arc ... ntu/stable

Also, pypi is a possibility, through e.g 'sudo pip install libtorrent==1.2.*'.

I think I may have gotten to a solution. Clearly the culprit was a bad libtorrent so I went about updating it. It updated to version 1.2.4.0 and Deluged was able to start since Libtorrent now had a version number however I was getting errors for all HTTPS trackers. Finding that this was likely due to an incorrect version of Libtorrent I went about basically purging everything relating to Deluge and Libtorrent and starting from scratch. Upon installing Deluge and Deluged once more I was greeted with a successful startup of the daemon.

I may have been able to get away with a less broad approach however I don't notice any lasting consequences of this. It's refreshing to know that things are now clean and working from a fresh install.

Thanks so much for the direction!

[ambipro]

The https tracker error may be due to validation of certificates, you can download the ltConfig plugin viewtopic.php?f=9&t=42887&start=210 and after enabling it, scroll to the bottom of the list and select validate_https_trackers checkbox on the left to enable options and make sure it is unchecked on the right checkbox.

You'll want to apply at startup as well.

Common issue.

I'm glad to hear, and you're welcome Btw, I mentioned ubuntu 18.04 before, because looked up that mint 19.3 is based upon that, which I forgot to mention. Anyway, if was using libtorrent 1.1.x originally, then the error would state so(not fullfiling requirement of libtorrent==1.2>), and the attribute still available as said, so indeed something must've been wrong with that => 1.2.x install, but as said glad you fixed it, and thanks for reporting back.

Just in addition to ambipro's helpfull advice above, then libtorrent from some places, e.g. pypi, needs a env-var added to even support https trackers at all:

Code: Select all

export SSL_CERT_FILE=/etc/ssl/certs/ca-certificates.crt

...But if just one specific one failing, or alike, then nice trick ambipro posted above.
