May this sound funny, after my migration form ubuntu 20 to 22 something go wrong some function don't work properly i don't have time to fix problems.

So i decide back to 20.04

i create live usb , erase disk and install clean 20. I had prepare backup in timeshift and deja-dup. I restore my files with deja-dup and system files with timeshift and there is the problem after the restore process root and swap file system can't be mounted.

I looked for a problem and found that I should change the labels in fstab. I change it to properly and it's work system can start, after update packages everything work but I see that it has a lot of partitions

what should i do?

With UEFI system, better to use gpt. You show extended partition which is from old MBR(msdos) partitioning. Microsoft has required gpt with UEFI, but Ubuntu lets you use MBR, but probably should not or at least issue warning. But why all the FAT32 partitions? Do you have data in those partitions? With UEFI, you only must have the ESP and / (root). And FAT32 not recommended for data as it does not have journal nor can have files over 4GB. But conversion from MBR to gpt erases drive, so good backups required.

For a guide on converting from MBR to GPT with Linux, without data loss (backup advised), see [this link](https://askubuntu.com/questions/1314111/convert-mbr-partition-to-gpt-without-data-loss).

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.
