[Linux] Offline build is failing, failure in name resolution

[tinywrkb]

I'm updating the qutebrowser Flatpak packaging and enabling python-adblock support.
I need to compile from source as there's no aarch64 binary release.
Flathub forbid network access during build-time so we build in offline mode.

Offline build is failing with

Is there anything useful that can help pinpoint the source of this issue? I can try generating a more detailed debug log if needed.

The packaging is in my adblock branch here, and specifically the python-adblock build commands are here.

p.s. It would be nice if binary releases for Linux aarch64 would be available.

Thanks for pointing this out in an issue. This has been a pain for other (actual and potential) packagers of python-adblock. The problem is that one of our transitive dependencies tries to fetch the public suffix list from the network. I think this may have been fixed in a recent version of addr. I'm in the process of updating now.

Regarding ARM packaging, I agree. Especially given the new Macs. See https://github.com/ArniDagur/python-adblock/issues/11.

@ArniDagur thanks for the reply. Let me know if testing is needed.

[rushmorem]

Yes, the recent versions of the psl crate no longer try to download the list at build time. Once you successfully update adblock-rust, this will go away.

[ArniDagur]

Hopefully the problem should be fixed now. If it's not, feel free to reopen this issue or create a new one.

Thanks, I can confirm that it's now building correctly for me without network.

p.s. I can successfully build now for aarch64.
