Installing Ubuntu problem "the partition assigned to starts at an offset"

24,071

Solution 1

Just switch from ext to xfs format, fixed the problem from me

Solution 2

First, I recommend you read this page for background on the problem.

Second, you need to use a partitioning tool that enables you to view and specify partition start points to the sector, rather than rounded (2MiB or 12.7GiB or whatnot). I'm not sure if the Ubuntu installer can do this, offhand. You may need to quit from the installer and use a tool like gdisk, which comes with Linux emergency CDs like System Rescue CD. Alternatively, most tools align partitions properly by default. I thought that the Ubuntu installer did this, but either it's got a bug or you prepared your partitions using some other tool. If the latter, you could simply delete the partition and re-create it with the Ubuntu installer to fix the problem.

If you need more help, I recommend you boot an emergency disc and show us the output of one of the following two commands:

sudo gdisk -l /dev/sda
sudo parted /dev/sda unit s print

      You are mixing up your sda and sdb. According to the picture, sda5 is an ntfs windows recovery partition and it is sdb5 that the installer is complaining about. How did you create that partition, and you need to have gdisk list sdb, not sda.

    Thank you Roshan for your simple quick solution. It worked for Ubuntu 18.04 on USB SSD.
