Hello Vivien, Vivien Kraus skribis: > I'm trying to install guix on my system. I have the 1.0.1 patch, but I > had the same problem with 1.0.0. We fixed a bug similar to what you describe in 1.0.1: https://issues.guix.gnu.org/issue/35783 Can you confirm that the backtrace you posted comes from 1.0.1 and not 1.0.0? (It seems to be from 1.0.1 accordingly to the line numbers, but better be on the safe side.) > In ice-9/boot-9.scm: > 829:9 19 (catch srfi-34 # ./gnu/installer/steps.scm:144:7 ()> # ./gnu/installer/steps.scm:144:7 (key c)> _) > 829:9 18 (catch srfi-34 # ./gnu/installer/steps.scm:144:7 ()> # ./gnu/installer/steps.scm:144:7 (key c)> _) > 829:9 17 (catch srfi-34 # ./gnu/installer/steps.scm:144:7 ()> # ./gnu/installer/steps.scm:144:7 (key c)> _) > 829:9 16 (catch srfi-34 # ./gnu/installer/steps.scm:144:7 ()> # ./gnu/installer/steps.scm:144:7 (key c)> _) > In ./gnu/installer/steps.scm: > 182:21 15 (_) > In ./gnu/installer/newt/partition.scm: > 755:33 14 (run-partitioning-page) > In ./gnu/installer/parted.scm: > 1010:14 13 (auto-partition! #< bytestructure: > #> #:scheme _) > 870:21 12 (loop _ _ _) > 863:17 11 (loop _ 1962582833 967694336) > 771:25 10 (mkpart #< bytestructure: # 0xbddb10>> _ #:previous-partition _) > In parted/structs.scm: > 552:19 9 (pointer->partition _) > 132:3 8 (pointer->bytestructure # > #) > In unknown file: > 7 (pointer->bytevector # 88 # > #) > In ice-9/boot-9.scm: > 751:25 6 (dispatch-exception 5 null-pointer-error > ("pointer->bytevector" "null pointer dereference" () ())) > In ice-9/eval.scm: > 619:8 5 (_ #(#(# > #< name: newt init: # exit: > # exit-error: # key args)> final-p...>) ...)) > 619:8 4 (_ #(#(#(# > #< name: newt init: # exit: > # exit-error: # key args)> fi...>) ...) #)) > In ice-9/ports.scm: > 462:17 3 (call-with-output-file _ _ #:binary _ #:encoding _) > In ice-9/eval.scm: > 619:8 2 (_ #(#(# > null-pointer-error ("pointer->bytevector" "null pointer > dereference" () ())) #)) > 159:9 1 (_ #(#(# > null-pointer-error ("pointer->bytevector" "null pointer > dereference" () ())) #)) > In unknown file: > 0 (make-stack #t) > ice-9/eval.scm:159:9: In procedure pointer->bytevector: null > pointer dereference Is it 100% reproducible for you? Could you post the output of “fdisk -l /dev/sda” (hit Ctrl-Alt-F3 and run that command)? Does the problem occur when you choose the “manual partitioning” method instead of “guided partitioning”? Thanks, Ludo’.
