Apparently your 'bootstrap_override' setting is bad. Could you share the value of this setting with us? (You should be able to find your tribler.conf in ~/.Tribler/).

@qstokkink @FFY00 this is caused when running the Tribler version from a few commits ago (when we were using a different kind of value for the bootstrap_override option. Removing the bootstrap_override option in the configuration file should fix it.

[FFY00]

bootstrap_override is None. I removed it from tribler.conf and it worked.

I released the package: https://aur.archlinux.org/packages/tribler/
I am gonna add a pinned comment warning about this issue.

Thanks :smile:.

[FFY00]

I am sorry, should I keep this open?

[devos50]

Nope, thanks for creating the package for arch linux, very helpful 👍
