Basically, what happen is that it is trying to delete a file that no longer exist on your system.
Easiest way to fix it is to create an empty file in that location.
On your example, the relevant part is the Satellite ID and the Piece ID.
I use this link to convert the Satellite ID to Blolbs folder Satellite info (Address, ID, Blobs folder, Hex)
12EayRS2V1kEsWESU9QMRseFhdxYxKicsiFmxrsLZHeLUtdps3S = ukfu6bhbboxilvt7jrwlqk7y2tapb5d2r2tsmj2sjxvw5qaaaaaa
KDRT4Y43NLVQM3L4OST5MUMK6ASHHR5TJTUGVBXAREO3IFHM6TUA = kd/rt4y43nlvqm3l4ost5mumk6ashhr5tjtugvbxareo3ifhm6tua.sj1
So you need to create a empty file in your blobs folder ukfu6bhbboxilvt7jrwlqk7y2tapb5d2r2tsmj2sjxvw5qaaaaaa/kd/rt4y43nlvqm3l4ost5mumk6ashhr5tjtugvbxareo3ifhm6tua.sj1
The next time it does its delete check, it will find the empty file and delete it.
I had to do this on 3-4 of my nodes, usually for this same Satellite ID.
