Greetings everyone,
Regrettably, my first post to this forum is a frustrating issue. Please bare with me though, as I am relatively new to the world of Ubuntu/Linux.
I have daily driven Ubuntu 20.04 on my work laptop for the last several months, but a week ago I had the wonderful inspiration to upgrade to Ubuntu 21.04. This upgrade resulted in my no longer being able to boot from my encrypted drive.
My first troubleshooting steps involved booting up a live USB and launching the boot repair tool, but the options to do anything with GRUB or MBR are disabled/greyed out. Here is a link to the pastebin output file.
I have also attempted to reinstall GRUB after decrypting and mounting the drive/partitions, but the system still refused to boot.
Here is an "lsblk" output for the drive:
Currently, the only way I can get the option to boot is by having the Ubuntu 21.04 live USB connected to the laptop as the primary boot option, and then selecting "Boot from next volume" from the GRUB menu to boot into my system.nvme0n1 259:0 0 465.8G 0 disk
├─nvme0n1p1 259:1 0 512M 0 part /mnt/boot-sav/nvme0n1p1
├─nvme0n1p2 259:2 0 732M 0 part /boot
└─nvme0n1p3 259:3 0 464.5G 0 part
└─nvme0n1p3_crypt 253:0 0 464.5G 0 crypt
├─vgubuntu-root 253:1 0 463.6G 0 lvm /
└─vgubuntu-swap_1 253:2 0 980M 0 lvm [SWAP]
At this point, I honestly have no idea what else I can try to get out of this predicament...
Any assistance with regards to this issue would be much appreciated.
