Since my update today, my boot is malfunctionning, and I get the following error message :
`Gave up waiting for root device. Common problems: -Boot args (cat /proc/cmdline) - Check rootdelay= (did the system wait long enough? -Missing modules (cat /proc/modules; ls /dev`
and a message saying that my UUID does not exist.
So I booted on previous kernel (5.4.0-42-generic) as recommended in a question asked here a few month ago. But when I try to update the -47 kernel with the command
sudo update-initramfs -k 5.4.0-47-generic -u
nothing happens and the computer still try to boot on the most recent (and faulty) one.
Is there anything else to do and is anyone else facing this trouble with this new kernel?
Or did I do something wrong somewhere when trying to fix the problem?
Thanks in advance for your help.
