I did tests in two directions:

1)
On the source host I run:

$ podman run -it docker.io/library/busybox

which gave me a local additional image and I transfered this to the
target host:

$ podman images
REPOSITORY TAG IMAGE ID CREATED SIZE
localhost/suse latest c87c80c0911a 46 hours ago 6.31 GB
registry.suse.com/bci/bci-base 15.4 5bd0e4152d92 2 weeks ago 123 MB
docker.io/library/busybox latest 9211bbaa0dbd 3 weeks ago 4.5 MB

$ podman image scp 9211bbaa0dbd srap57::
Copying blob 82ae998286b2 done
Copying config 9211bbaa0d done
Writing manifest to image destination
Loaded image: sha256:9211bbaa0dbd68fed073065eb9f0a6ed00a75090a9235eca2554c62d1e75c58f

i.e. this was transfered fine and shows up on the target host as:

srap57dxr1:~> podman images
REPOSITORY TAG IMAGE ID CREATED SIZE
<none> <none> b677170ada05 3 minutes ago 1.89 GB
registry.suse.com/bci/bci-base 15.4 5bd0e4152d92 2 weeks ago 123 MB
<none> <none> 9211bbaa0dbd 3 weeks ago 4.49 MB

apitzm@srap57dxr1:~> podman run -t 9211bbaa0dbd
/ #

2)

I copied over the files to build the image to the target host:

apitzm@srrp02dxr1:~$ scp -rp suse srap57dxr1:.
Dockerfile 100% 5051 1.2MB/s 00:00
initSunRise.sh 100% 953 314.2KB/s 00:00
postgresql.conf 100% 29KB 5.0MB/s 00:00
testdb.dmp.gz 100% 388MB 110.0MB/s 00:03
keyFile 100% 893 63.2KB/s 00:00

and built the image there with:

apitzm@srap57dxr1:~> podman build -t suse suse
...
which worked also fine:
...
STEP 58/59: ENTRYPOINT /usr/local/bin/start.sh
--> 86dab7ac3e4d
STEP 59/59: STOPSIGNAL SIGQUIT
COMMIT suse
--> a1ffb1f71791
Successfully tagged localhost/suse:latest
a1ffb1f717911b4e11aaa89d94c4959562c625b0e203dd906797e60d019cde57

The big difference between the image 'docker.io/library/busybox' and
mine is the size (4,5 MB ./. 6,1 GB). When I scp my big image I see in
/tmp that the sftp-server writes there a temp. file as:

ls -lh /tmp/tmp.RLHbJp9uzq
-rw------- 1 apitzm apitzm 5.8G Jan 11 10:58 /tmp/tmp.RLHbJp9uzq

and when this reached the size of 6 GB it gets deleted

3)
I removed all container files on the target host:

srap57dxr1:/ # rm -rf /data/guru/containers/*
srap57dxr1:/ # du -sh /data/guru/containers/
1.0K /data/guru/containers/

and started a fresh scp:

$ podman image scp c87c80c0911a srap57::
...
Copying blob a5a080851ed7 done
Copying blob 6fc7ff0cb132 done
Copying config c87c80c091 done
Writing manifest to image destination

When the transfer has ended on the target host one can see
1. the big file in /tmp gets deleted
2. something was written below the area of the containers (which was
empty before):

srap57dxr1:/# ls -lh /tmp/tmp.5uuhYWqqQT
-rw------- 1 apitzm apitzm 4.3G Jan 11 11:35 /tmp/tmp.5uuhYWqqQT
srap57dxr1:/# ls -lh /tmp/tmp.5uuhYWqqQT
-rw------- 1 apitzm apitzm 5.9G Jan 11 11:37 /tmp/tmp.5uuhYWqqQT
srap57dxr1:/# ls -lh /tmp/tmp.5uuhYWqqQT
ls: cannot access '/tmp/tmp.5uuhYWqqQT': No such file or directory
srap57dxr1:/# du -sh /data/guru/containers/
1.1G /data/guru/containers/

How can I get more messages about the failing process?

I am not at war with Russia. Я не воюю с Россией.
Ich bin nicht im Krieg mit Russland.
