i'm having some issues with my freshly installed 20.04 LTS. To begin with my Laptop has 2 drives, a 256G SSD (sdb) and a 1T HDD (sda). I just reinstalled Ubuntu using LVM and a full system encryption (following this post) onto the SSD. I than went ahead and moved my /home partition to the HDD, encrypted it as well and set everything up so it'll decrypt along with the root partition. This all worked really well (for the detailed steps see Andor Kiss's reply on the above linked post.
The problem i'm having is that after installing some essential programms the system keeps telling me the root partition is running out of space and i can't install any more packages. My guess is that LVM is still reserving space on the SSD for the /home partition (which i did save from the previous installation and which is quite large with a music library and some backups and stuff), but i can't really tell for sure. Does anybody maybe have a clue on how to resolve this?
I'll put some info below which i think might help:
