I contact you for technical assistance, I have a DELL INSPIRON 3480 notebook, Intel Core i5 ​​8265U, 16GB RAM, SSD NVME M.2 240GB, HDD 300GB, which I was using with UBUNTU 18.04LTS. When updating to UBUNTU 20.04 LTS, it began to present problems when starting the OS, after loading GRUB I get the following errors:

/dev/nvmen1p1: recovering journal

This error prevented the operating system from starting. I managed to solve it by adding the following to the GRUB parameters: libata.noacpi=1, but with each update of KERNEL the problem appears again.

Please help solving this problem.

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.
