I was attempting to upgrade my Guix (binary, on Linux Mint) installation today using the 'guix package pull && guix package -u' commands, and Guix outputted the following error:
ERROR: In procedure raise: Wrong type (expecting exact integer): #<condition &message [message: "Guix is too old and cannot be upgraded"] 7528ac0> guix pull: error: You found a bug: the program '/gnu/store/y1kqj5ikxx9niyz2zx1gbikspi2xfmi4-compute-guix-derivation' failed to compute the derivation for Guix (version: "7e143375d3649f3c0bd4c13958b26c086f364647"; system: "x86_64-linux"; host version: "aa4818c33b6b2fd8d602ee93a2f53005d9472f41"; pull-version: 0). Please report it by email to <bug-guix@gnu.org>. I searched the Web and mailing list archives for this error but could not find anything. Maybe I used the wrong keywords. Is there any way I can perform a "manual upgrade" to a newer Guix version?
