If you want to use the msdos partition table with more than 4 partitions, it is required to create 3 primary partitions + 1 extended partition + X logical partitions.
There is a problem when creating the extended partition, that if you don't specify a size, the installation fails with:
yaml: https://pastebin.ubuntu.com/p/dgTWBwkFmj/
Error: https://pastebin.ubuntu.com/p/qb68W6CPFn/
So, I tried to specify the size as -1, given that I want to create the extended partition with all disk space that I have left, so then I create the logical partitions, but this fails complaining that the partition has negative size but is not final partition of Disk:
yaml: https://pastebin.ubuntu.com/p/HXrkFCZB8p/
Error: https://pastebin.ubuntu.com/p/3Sk4FdsQ8c/
It works well if I specify the size of the extended partition in GB (which is not what I want):

Pasting the config that we expect Subiquity to accept once it is fixed ; just in case the pastebin expires. Source: https:/
