   I'm a newbie and I installed Ubuntu 18.04LTS about 5 years ago   
   separating root, home and my storage files in 3 different partitions of   
   my hdd. Now I've to switch to 22.04 release and I'd like to prevent most   
   probable issues I can meet in this upgrading. Here are my questions:   
      
   1) What's the size you suggest for my new home partition?   
   Now my root is 50GB (only 20GB used) and home is 10GB (only 5GB used)   
   but afaik in new Ubuntu releases there's a different sw management with   
   snaps so home is much bigger than in the past with the same sw installed.   
      
   2) What's the least probably problematic way to get a new ubuntu   
   22.04lts root from 18.04lts keeping my home as it's now: 2 consecutive   
   automatic system lts upgrades or just one fresh installation by bootable   
   usb?   
      
   3) Could I keep on using 4.18 kernel with 22.04 Ubuntu?   
   In the past I've got graphical issues with older kernels (system freezed   
   sometimes!) and 4.18 kernel solved these issues. I tried a couple of   
   later kernels (5.*) as well but they were worse so now I'd prefer to   
   keep on using 4.18 for first then I'll try the latest one (6.*) but I'd   
   want to be sure I can boot 22.04 choosing 4.18 kernel from my grub as I   
   do now with 18.04.   
   I've already downloaded 22.04 and tried it in a live session and it   
   seems there're no issues, not outright, so I'm quite trustful.   
      
   Any other suggestion/correction for my upgrading or new installing will   
   be appreciated, thanks in advance.
