Ubuntu 21.10

I setup a fully functional PXE server but lately I received an error.

I followed this

/etc/exports:

/netboot/nfs *(rw,sync,no_wdelay,insecure_locks,no_root_squash,insecure,no_subtree_check)

this is Ubuntu 20.04 image

and bootchain stop. Why?
I have Ubuntu 16.04 Desktop on the same /netboot/tftp/pxelinux.cfg/default and 16.04 boots OK. Can anybody have a solution to that?

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
