Subject: bug#53151: Bug: Overlapping Partitions
Date: Sun, 9 Jan 2022 14:50:55 -0500

[Message part 1 (text/plain, inline)]

I think I found a bug in v3.4 of GNU Parted.

This was my issue, put in removable media that had old Root and Home
labelled partitions but they were mounted at /media/USER/xxxx.  I wanted to
format and i got an error about overlapping partitions.

I used sfdisk to check my sectors start and end.

I outputted the partition table data to a text file and edited the overlap
as I did find one on /dev/sdb. I used sfdisk -d /dev/sdb >
~/Desktop/sdb-backup.txt

After editing this text file to fix the overlap as my sdb1 end overlapped
my sdb2 start, i re fed the new partition data back in with

sfdisk /dev/sdb < ~/Desktop/sdb-backup.txt

After being confident i fixed the overlap that was causing Parteds GUI to
not open and the partitions were resized after feeding new adjusted data
sectors to the disks with sfdisk,

I got this print out when using a command: parted /dev/sdb unit s print  to
confirm the changes took place.  My terminal spit this out
