Comment 3 for bug 1406599

thank you. it seems to be an issue of the lsblk commands.
I have temporarily disabled those 2 commands in the PPA. (boot-repair version 4pp29)

Please :
1) indicate the output of the following four commands (check if any strange behavior):
LANGUAGE=C LC_ALL=C lsblk -o NAME,TYPE,FSTYPE,SIZE,LABEL,MODEL,UUID
LANGUAGE=C LC_ALL=C lsblk -o KNAME,ROTA,RO,RM,STATE,MOUNTPOINT
lsblk -o NAME,TYPE,FSTYPE,SIZE,LABEL,MODEL,UUID
lsblk -o KNAME,ROTA,RO,RM,STATE,MOUNTPOINT

2) retry with last PPA version, and tell me if you reproduce the bug or not.

3) from live-session, install Boot-Repair from PPA (do not start it yet), type "gksudo gedit /usr/share/boot-sav/gui-scan.sh", uncomment line 63 (#LANGUAGE=C LC_ALL=C lsblk -o KNAME,ROTA,RO,RM,STATE,MOUNTPOINT) by removing the # at the start of the line, save the file, then run "boot-repair" and tell me if you reproduce the bug or not (if you reproduce, please send me the 2000lines)
