I attempted to upgrade my 20.04 to 22.04 and upon reboot get Kernel
Panic not syncing VFS: Unable to mount root fs on unknown block

I am using kernel 5.4.0-110-generic and it looks like the upgrade
removed any previous kernels so I don't have to option to try another
kernel.

I am dual booting with Mint Linux on another drive so can at least
access my failed system.

I'd appreciate help on how to fix this.

Thanks

Did you back up your 20.04 drive? If you did use the backup to write
over the mess.
Do you have a copy of the 20.04 iso file from which you installed or
one of the later updates,Look for 20.04.3 or 20.04.4
as good iso files. Search for it using DuckDuckGo or whichever
search engine you find convenient.
Here is a link that you might find useful.

22.04 is not a good item. Canonical did not properly vet
the new iso file and it is quite deficient in use.

Fedora pulled a similar boner with the latest version so
the big famous publishers are apparently tired of doing the very
hard work.

you might not have been caught unaware of the 22.04 problems

S

I have an older backup but found the problem
I was booting from Grub on my Mint installation so once I updated it
there I was all ok>

Anyway Ubuntu 22.04 is now working but performance is not as good as
20.04 I think I will get an SSD.
I am giving up using mechanical drives.

One other bug after the upgrade is that Firefox saved all my book marks
but none of my passwords.

If I re-enter my password for one account it worked and stays working
after I shut down FF then re-open...but then I look in Saved Logins
nothing is listed

At any rate I was fully aware that I should have waited a few months
before I upgraded but since I have Mint on an SSD I can just use that as
I slowly tweak my Ubuntu installation.

I had a ton of project that I finished so needed a new challenge for the
upcoming weeks.

I have a number of other machines so if one system is a bit buggy, it's
not the end of the world

Thank you

(Probably too late to the thread, if baseline install is toast)

I've never tried to update a YY.04.0 release; IMO, that release
is too volatile (as noted).

I wait at least for YY.04.1 release, and use do-release-upgrade
(the plain vanilla release upgrader).

More info:

man do-release-upgrade

where are firefox passwords stored
in google search gets me About 2,470,000 results (0.49 seconds)

To eliminate the problem in the future I suggest searching for
set firefox default profile

Before I upgraded, they were in "saved logins" as they are on all my
other FF installations.

After the upgrade to 22.04 "saved logins" is blank>

I even imported a profile from my Mint installation

I now changed my default boot to Mint and do not plan on using Ubuntu 22.04

I've got a 20.04 backup that I'm going back to.

My advice to all is stay away from 22.04.

I may fool with 22.04 at some later date but for now I'm going back to
my 20.04 backup and will use Mint as my default boot.

Fixed it. Problem caused by snap

rm -rf ~/snap/firefox

Maybe I will keep fooling with 22.04 and go on

22.04 Firefox default install is a snap and profile is at a different
path. I just removed the snap version and installed the native install.
Google "install deb version of firefox ubuntu 22.04". Not only does it
fix the profile path issue, but the deb version of Firefox will allow
GNOME Shell Extension installs

Take care,

Now that I've been using the system for a while all seems to working ok
with two exceptions.

Vivaldi and Opera were no longer working so I removed them. Will try a
fresh install and see what happens.

Brave browser and Chromium were OK though
