I recently installed the new Ubuntu 20.10, after the first reboot when I choose Ubuntu from grub's black screen I got this error
[ 0.298008] Initramfs unpacking failed: Decoding failed
/dev/sdb5: Clean, 207672/6225920 files, 3573307/24882688 blocks
I search the internet for a solution and I got and apply this one:
I changed COMPRESS=lz4 to COMPRESS=gzip in /etc/initramfs-tools/initramfs.conf
then sudo update-initramfs -c -k $(uname -r)
Then I tried to boot to the normal Ubuntu, I got this error
/dev/sdb3: Clean, 203431/6234112 files, 2806098/24907008 blocks
and during these error messages, my PC fully stuck and I cannot hit CTRL/ALT + F1 or F2
And when I want to open Ubuntu I enter the [Recovery Mode] with messy resolution and bad graphics!
My PC specs
MB: MSI B450 Tomahawk Max
CPU: AMD® Ryzen 5 1600AF
GPU: AMD® Rx 570 4G <<< I think Ubuntu cannot install the driver, and the official driver is showing me an error also!
MEM: 16G
SSD: sda [Windows] 120G
HDD: sdb [Ubuntu] + Data on ntfs drive
Kindly help me to sort this problem out, Thanks in advance.
