Hello!
I just tried to "guix pull" on my Debian Buster GNU/Linux system. Twice it made the system completely freeze for a few seconds and then reboot. And that third time it didn't crash the system but the guix pull failed and returned this error:

Can somebody help me please?

(Before doing the third "pull", I did an "apt update" and "upgrade", but I wasn't that much behind in updates, I had done it less than a week ago last. My last "guix pull" was made at the same time as the "apt update", a few days ago.)

Hoping I can resolve this soon or that my feedback was positive for the development of Guix. =)
I can provide log debug info (if there is any) upon request.

Best regards!
