Can't start deluge [Ubuntu 19.10]

[elRestaurador]

Hi, I can´t start deluge. I always get a

Code: Select all

double free or corruption (out)
Aborted (core dumped)

I've uninstalled it several times, installed from cli and downloading the file. Always same result.
Any ideas?

When googling the error, I stumbled upon your old post regarding this issue. Have you tried removing the qbittorrent PPA, so only having libtorrent.org or deluge PPA for libtorrent, and trying again, reinstalling all?

(For others, in old thread Cas stated qbittorrent PPA's libtorrent builds have issues with python3 giving said error upon running deluge. Unless fixed in meantime of course, but not that old thread, about 5 month'ish: viewtopic.php?t=55392 )

I've performed a

Code: Select all

sudo add-apt-repository --remove ppa:qbittorrent-team/qbittorrent-stable

Reinstalled deluge and nothing.
Then performed:

Code: Select all

sudo add-apt-repository ppa:libtorrent.org/1.2-daily
sudo apt-get update
sudo apt-get install libtorrent-rasterbar

Last line output was

Code: Select all

E: Unable to locate package libtorrent-rasterbar

Then tried to launch deluge and got

Code: Select all

double free or corruption (out)
Aborted (core dumped)

Sorry I have no experience with Ubuntu, never tried it honestly. I just checked that libtorrent 1.1.13 is available in Ubuntu 19.10 by default(and deluge 2.0.3), so remove all PPAs regarding libtorrent, deluge and qbittorrent etc, and reinstall from default sources(deluge and libtorrent-rasterbar9).

I was having the same error with deluged (as a thin client) on ubuntu 19.10.
The solution that worked for me was add the PPA of libtorrent1.2-daily, then remove the qbittorrent PPA, and finally remove libtorrent-rasterbar9, that will automatically install libtorrent-rasterbar10 and some other stuff that i can't remember... sorry

Code: Select all

sudo add-apt-repository ppa:libtorrent.org/1.2-daily
sudo apt-get update
sudo add-apt-repository --remove ppa:qbittorrent-team/qbittorrent-stable
sudo apt-get remove libtorrent-rasterbar9

As far i can tell it didn't broke anything else.

Hope it work for you!

What version of deluge are you trying to run?
Could you please post the results of "apt-cache policy |grep http |awk '{print $2 " " $3}' |sort -u" and "apt-cache policy deluge" and "apt-cache policy libtorrent*"?
Thanks

upgrade to 20.04 LTS
delete and purge all deluge ppa, as 20.04 has a working version of 2.0.3, maybe 19.10 has it too.

downgrade to deluged/focal,focal,now 2.0.3-2

and you will need to upgrade to libtorrent1.2:

sudo add-apt-repository ppa:libtorrent.org/1.2-daily
sudo apt-get update
sudo apt-get install python3-libtorrent

# deluged --version
deluged 2.0.3
libtorrent: 1.2.11.0
Python: 3.8.5
OS: Linux Ubuntu 20.04 focal
