I have slow internet :)

It looks like ftp://tug.org has a FTP session timeout of 2 hours 11 minutes, or something like that.
Over night I tried to build sbcl and failed. Note how download silently stopped at ~80% [1].

Would be nice if guix had a mechanism to reconnect to FTP and continue download after timeout.

Thanks!

In the meantime, you can download the files with a resumable tool like
wget, and then use `guix download file:///path/to/file` to work around
this missing feature. Note that both the client *and* the server must
support resuming downloads for this to work.

The workaround worked.

I've noticed it took guix-daemon 2GB of RAM to process this file locally.
Does guix keep all the file in RAM until download finishes?

Thank you!

I haven't looked, but that's how I'd expect it be coded. The OS can
handle paging things in and out as needed, right?

Fundamentally, I think we should just fix our ‘texlive’ package such
that it doesn’t download 4G at once…
