Do the following journal lines identify the problem? Or is it something separate, such as a hard drive going bad?

If it is IPV6 related, I have tried all the ways I know to shut off IPV6. Is there a list of things
to be done?

It's most likely one of the indexing programs such as akonadi/baloo. I always disable it on my systems.

$ tail -n 1 ~/.config/akonadi/akonadiserverrc
StartServer=false
$ head -n 2 ~/.config/baloofilerc
[Basic Settings]
Indexing-Enabled=false

Disable akonai and balloo, and reboot.

Disabling ipv6 should only be done if your isp does not support it, which should
be very rare. I found out mine had enabled it, but I couldn't get it to work until
I replaced my router, even though the old one claimed to support it.

If you do need to disable ipv6, reboot after creating a file ...
# cat /etc/sysctl.d/10-disable-ipv6.conf
net.ipv6.conf.all.disable_ipv6 = 1

I think I have tracked the problem, or at least part of it, to avahi-daemon. the file avahi-daemon.conf contained a line useipv6=yes under [server], and
as mentioned previously I have disabled ipv6. I suspect that resulted in repeated failure to try to set or do something. The line now is useipv6=no, and things seem to be working ok.

My desktop is Gnome. akonadi and baloo have been removed from the system.

$ tail -n 1 ~/.config/akonadi/akonadiserverrc
StartServer=false
$ head -n 2 ~/.config/baloofilerc
[Basic Settings]
Indexing-Enabled=false

Disable akonai and balloo, and reboot.

I disabled ipv6 years ago, because I was not prepared to reconfigure the firewall to include it, and I did not think I needed it. Thinking back,
I think verizon fios at the time did not support it, but I am uncertain
on that.

Is there any reason I really need ipv6? Services and websites I
use all seem to work, and it just adds one more opportunity
for hacking and cracking via the net.

If you do need to disable ipv6, reboot after creating a file ...
# cat /etc/sysctl.d/10-disable-ipv6.conf
net.ipv6.conf.all.disable_ipv6 = 1

Do I really need the above? If so, where should I put it? My
sysctl.d contains:

ls -l /etc/sysctl.d
-rw-r--r-- 1 root root 307 May 12 2021 51-alt-sysrq.conf
-rw-r--r-- 1 root root 235 Dec 24 2023 51-drakx.conf
-rw-r--r-- 1 root root 304 Mar 8 2022 tales.conf

https://www.networkacademy.io/ccna/ipv6/ipv4-vs-ipv6 has a discussion on
it. Most of the information is WAY over my head, but you are better
versed in that area.

One advantage is supposed to be increased speed, but I don't notice a difference, as yet. That could be because I still have memories of the
s l o w speed with my original "Fixed Wireless" ISP, and even worse, my dial-up days.

Increased speed would be significant for sending huge files. IPV4
is limited to 64K packets but IPV6 can send truly huge packets.

There is a tiny increased speed for IPV6 due to few header fields.

I see no good reason to go through the process needed to add IPV6
to IPV4.

Cheers!
