I'm going back outside in a moment, but I'll make the general

My Settings, My profile <=== Tend to be in /home/davey

Program Files (whether SNAP or .deb based) are not in /home/davey

Keep your eyes open on this one

cd ~
ls -a

Possible strings would include "mozilla" with the dot in front for
a hidden file/directory, but they could also put Thunderbird at first
level, or Firefox at first level.

Maybe you are one of those people who mount things in layers,
and have "separate storage" for a lot of your stuff. It may be that
for some reason, part of your mount lines is not working, and "materials"
have disappeared from /home/davey.

The whole intention of having a "home" is as a place to store your goods.
Like profiles for some of the tools, will live there.

As another example of "mount accidents", sometimes a mount
does not happen, and your software starts writing new empty
materials right onto the mount point. Your job is not to be
deceived by this.

My email folder is more than 1GB. If I do a search and an item
with only 20 megabytes of files shows up, then I know that's
not my real profile. Then I do

df # the diskfree command

and get a list of the mounts and see if some part of my
empire is not working at the moment.

While you can *erase* things by accident, by far the
more likely explanation is a thing is *lost* :-)
And your job is to find it again and set it right.

I've done a few Upgrades on Ubuntu, and nothing untoward
happened to any profiles. It was all still there. On some
occasions, I had to restore my setup from backup, because
I forgot a step from preparation. Upgrades can be
broken by custom-installed materials, and you're supposed
to keep crib notes for later, as to what things need to be
removed, before the Upgrade process kicks off. I usually
get it right after the second or third try.

I am having so many problems with this 22.04 that I am just going to
limp along for now, I have most of the important stuff functioning, and
then try both 24.04 and then Linux Mint as alternatives. But screwing
around with this has waste so much of my time that I need to get my
other life back up-to-date, and then come back to this later. I am not knowledgeable enough to fix this on my own.
One thing that got better: Automount appears to have some functioning
now. But that's about it!
Thanks for all the help.

For now, I have a system which is basically functional.

I have the earlier installation of Ubuntu 22.04 on my newish desktop,
done a few months ago.
This one, on the daily-use laptop, was done a couple of weeks ago, from
the same USB stick. Both were clean installations.

I now have working: Facebook, Thunderbird, Clawsmail. I still cannot get
Local Folders working properly either.
Also LibreOffice and Handbrake work on both.

gFTP, which I used before to move files between my laptop and my Humax
PVR, won't work on either machine. But Filezilla does.

VLC works fine on the desktop, but will not on the laptop.

Okular works on the desktop, I have not yet tried it on the laptop.
Ditto GNU Image processor.

On the laptop, I have sorted out the failing rsync scripts, and also
restored ssh operations based on the laptop. There are lots of other applications before that I will only try again as and when I need them.

So I am in a position where I can function almost as before, using the
laptop.
Yesterday, I ran Linux Mint on the desktop, which took ages to laod,
and at a first glance, it did not seem able to locate, and therefore
install, vlc. It did give me functioning Facebook and Thunderbird,
though. I did not try Clawsmail.
I assume that there is a different process to find and install other
programmes such as VLC, but I will not load Linux Mint again for a
while.

I now need to find how to move the Launchbar to the bottom of the
screen (GNOME?). Research later today.
And that's the state of play.

Linux Mint takes longer to load, because of the sheer weight of systemd commands it has in it. Presumably these came from Ubuntu. Some of
the specious Ubuntu materials get removed by Clem, and some other Mint
versions load quickly.

If you do this:

cat /etc/fstab

that shows mount entries that the installer process placed there.
The comments are the part of interest.

Your swap can be implemented as a partition (swapon -a),
or the swap can be a /swapfile (swap as a file, sitting on a
partition known to load). The OS gets "itchy" if it cannot
find a swap. It starts loading some RAID packages, scans
for ZFS or BTRFS, looks under sofa cushions for a swap.
And... this slows the boot process.

You can use the dmesg command

dmesg
sudo dmesg # If it complained on the first attempt

and you can see notations of things amiss in there. But
not all conditions (like the missing swap) are immediately
apparent. The "top" command can show the state of swap,
whether the quantity of swap is zero, or some swap is now
in service.

Returning to my Thunderbird problem. remember that it works almost
completely on the Desktop, including Local Folders. But on the laptop, I
cannot get the Local Folders to work. I shut down TB, then copy the
Local Folders files from the backup into the correct folder in the
working TB profile's folders, but they don't appear.

I was wondering whether to:

1. Create a new fresh profile, as there are some extra files and
remnants of old profiles floating around.
Or:

2.a. Purge Thunderbird, to get rid of anything that is incorrect.
Google seems happy to restore my .gmail accounts.
2.b. Reinstall TB from scratch. Use snap?

I have also found that my backed-up Local Folder files are not complete,
which puzzles me. They were done nightly using an rsync script. What's
gone is gone.
But I have some .msf files, which appear to contain loads of messages. I
need to see if I can convert them into individual messages again.

Any help welcome.

But I have some .msf files, which appear to contain loads of messages. I

Any help welcome.

.msf is Mork Summary File. It contains the headers of the messages.
in a database format. If a .msf is erased for example, a new one
can be re-built from available information.

In particular, if you had a large Inbox, and the Inbox.msf got
erased, Thunderbird will scan the Inbox file and make a new Inbox.msf .
The "status" of messages, such as whether they have been Read or not,
would not necessarily be correct.

The Inbox itself, is a text file, and it has a couple Mozilla status lines
at the top of each message. These are inserted by Thunderbird, so that when
a .msf is derived later, those status lines can provide some of the information needed. (Thunderbird also supports separate .eml files in a folder,
and can scan all of those to make a .msf .)

An IMAP account, may not have the same local file content as a POP3 account would.
One stores content on the server (such that multiple clients can be used to read emails without conflicting with one another). The POP3 is likely to populate
a master client with the emails, and can remove them from the server so that the
server is not clogged.

GMail is different, in that GMail stores internal mails in the AllBox (Google Server).
GMail uses comment lines like Mozilla Thunderbird does, only with
GMail they are "tags" indicating which boxes should receive a copy
of the message in the AllBox.

AllBox#1 Sent, Inbox # When you send an email to yourself, no TCPIP traffic results.
# The server simply adds the "Inbox" tag, to the "Sent" tag
# already associated with the message.

# You can examine your AllBox, using Google TakeOut
# for download of the box as a ZIP file. This is how I know
# what the tags are. I did a TakeOut to get my file.

Because GMail has this clever scheme, this can result in the odd surprise
for the user. Just as long as you remember that GMail has only one box,
it may be easier to understand how parts of the scheme work.

Recent versions of Thunderbird, do not particularly tolerate foreign
file types in the folder structure. I have had .7z files removed from
such folders -- the files used to be tolerated, but they get removed
on newer versions of the software.

The Inbox should be an MBOX format. There could be rules about
what character sets are allowed. It might be important, if manually
editing an MBOX file, to not change the character set to UTF-8 from ANSI
or similar. You want the file to be recognizable as an MBOX file.
If in doubt, use a hex editor, to see if any foreign material is present
in the file.

To give an example, I was having troubles one day. Using a hex editor,
I quickly scrolled through the file in question. *There was a hunk of binary* This can happen on a file system error, a disk problem, and so on. Once
I cleaned up the mess manually and removed the binary material (I can do that with the hex editor), the file worked again. I've only had one corruption
like that, in a lot of years usage.

You can use the Linux "file" command on an MBOX

file Inbox

and it will tell you what kind of text file it is. There are more
than 100 declaration types available from the file command, concerning
the contents of Text files. Some of the declarations indicate a
problem with the file that needs your attention (and in particular,
a quick check with a hex editor, to determine whether a major
corruption is present).

For further help, you can try this group. It was created after
the private Mozilla domain was disconnected. There is a group
with a similar name, for Firefox.

than 100 declaration types available from the file command, concerning
the contents of Text files. Some of the declarations indicate a
problem with the file that needs your attention (and in particular,
a quick check with a hex editor, to determine whether a major
corruption is present).

For further help, you can try this group. It was created after
the private Mozilla domain was disconnected. There is a group
with a similar name, for Firefox.

Briefly, as it's bedtime:

All of the problem messages were in Local Folders. so are not on the
Google server.

I want to unravel the .msf files I do have, rather than recreating
them. If it only contains the headers that's not much use.

I will certainly look at that group, many thanks.

I have just exported my current Profile, maybe tomorrow I will create a
new one from scratch and see what happens. At least I can use the
desktop if it all goes even more tits up than it is now, although
really it's only the Local Folders failure that is a real pain.

No sign of Firefox (nor TB, but that's probably in snap).

In all, this is pointless. I will try something different, whether
it's Ubuntu 24.04, or Linux Mint, which I am currently
downloading.

More later, thanks for help.

I'm going back outside in a moment, but I'll make the general
comment that these two things, are stored in different areas.

Big snip for brevity.

I've done a few Upgrades on Ubuntu, and nothing untoward
happened to any profiles. It was all still there. On some
occasions, I had to restore my setup from backup, because
I forgot a step from preparation. Upgrades can be
broken by custom-installed materials, and you're supposed
to keep crib notes for later, as to what things need to be
removed, before the Upgrade process kicks off. I usually
get it right after the second or third try.

For now, I have a system which is basically functional.

I have the earlier installation of Ubuntu 22.04 on my newish desktop,
done a few months ago.
This one, on the daily-use laptop, was done a couple of weeks ago,
from the same USB stick. Both were clean installations.

I now have working: Facebook, Thunderbird, Clawsmail. I still cannot
get Local Folders working properly either.
Also LibreOffice and Handbrake work on both.

gFTP, which I used before to move files between my laptop and my Humax
PVR, won't work on either machine. But Filezilla does.

VLC works fine on the desktop, but will not on the laptop.

Okular works on the desktop, I have not yet tried it on the laptop.
Ditto GNU Image processor.

On the laptop, I have sorted out the failing rsync scripts, and also
restored ssh operations based on the laptop. There are lots of other applications before that I will only try again as and when I need
them.

So I am in a position where I can function almost as before, using the laptop.
Yesterday, I ran Linux Mint on the desktop, which took ages to laod,
and at a first glance, it did not seem able to locate, and therefore
install, vlc. It did give me functioning Facebook and Thunderbird,
though. I did not try Clawsmail.
I assume that there is a different process to find and install other programmes such as VLC, but I will not load Linux Mint again for a
while.

I now need to find how to move the Launchbar to the bottom of the
screen (GNOME?). Research later today.
And that's the state of play.

I managed to get VLC working. Based on thoughts expressed in this
thread, I installed VLC using snap, and it worked exactly as expected.
One little victory.
I feel that I am at last getting to grips with this version of
Ubuntu, but it's been a long struggle.
Along with the now working xsane, it is getting workable at last.
The final deal will be if I can get a fully-working Thunderbird set up.
Later for that, busy today.

Thanks everyone for all the help, it is much appreciated.
