Tribler version/branch+revision: 26/12/2018 git code Operating system and version: Fedora 29

Hello, I'm trying to make tribler run on my Fedora 29. I've installed all the python modules required once at a time. But I'm now stuck on this error:

I've attached a screenshot which may be more readable. immagine

Thank you for your report! We had some issues in the past with the M2Crypto library on Fedora 29 since Fedora does not ship the required elliptic curve support by default. See https://github.com/Tribler/tribler/issues/893.

Unfortunately, the only workaround is to build the M2Crypto yourself, with the required ec25519 curve. You could also consider using a different Linux distribution (Tribler works correctly on Ubuntu/Debian and we recently support archlinux). Note that we will soon drop the M2Crypto library from Tribler and only rely on libsodium. When this will be done is not sure yet.

Since this is not a bug in Tribler itself, I will close this issue. Please let us know if you have any other questions, or need help with building M2Crypto 👍

Thanks a lot for your reply. In the future do you think you will release a appimage/snap/flatpack app? I'm not sure if it will be possibile, but this kind of packages are good for the users :)

devos50 commented 5 years ago

We have discussed Snap packages already and we have plans to make them. However, this is not very high on our priority list since we have more pressing issues (i.e. stability of Tribler itself) and our new (giga)channel functionalities :)

Ok. I'll wait for the next releases. Thanks a lot for your work.
