Hi Josselin,

Thanks for the answer.

Yes, that was it. I did the same procedure again, this time with a disk
of size 20 GB instead of 10 GB. The installation succeeded, and after the
installation 6-7 GB of the disk were used. But the qcow2 disk image was
14 GB large, indicating that the maximum use of the disk had been 14 GB.
So, yes, there must have been ca. 7 GB of data that were temporarily used
and deleted near the end of the installation process.

Suggestion: Extend the message "... but only 1,079.3 MB available in /mnt"
- either to include details about /mnt:
  "... but only 1,079.3 MB available in /mnt, mount point for /dev/sda2
   (file system type: ext4)"
- or to include details about the usage of /mnt:
  "... but only 1,079.3 MB available in /mnt, a file system with 8,543 MB
   total size, of which 7,421 MB are already in use"

Bruno
