How to debug "Cannot open SWUpdate IPC stream: No such file or directory"

[Geoffrey Lansberry]

I'm taking over and continuing some work that a former colleague had started a few years ago.  I have a simple swu file that works fine when run with swupdate -i, but does not work properly when using surricatta and hawkbit.  I'm not sure where to look, but found this group, and hope that someone here can point me in the right direction.

FIrst of all I should let you know that I'm trying to get an older version of swupdate  (v2021.11.0) to work with an older hawkbit (0.3.0)

The first error I get is this one:
Dec 11 14:13:40 bot08365 swupdate[26949]: [ERROR] : SWUPDATE failed [0] ERROR /home/symbotic/build/build_C0/tmp-glibc/work/var_som_imx8qxp-wrs-linux/swupdate/2021.04-r0/git/corelib/channel_curl.c : channel_get_file : 1197 : Cannot open SWUpdate IPC stream: No such file or directory 

And it's followed later by these two:
Dec 11 14:13:40 bot08365 swupdate[26949]: [ERROR] : SWUPDATE failed [0] ERROR /home/symbotic/build/build_C0/tmp-glibc/work/var_som_imx8qxp-wrs-linux/swupdate/2021.04-r0/git/suricatta/server_hawkbit.c : server_hawkbit_error : 196 : No suitable .swu image found
Dec 11 14:13:40 bot08365 swupdate[26949]: [ERROR] : SWUPDATE failed [0] ERROR /home/symbotic/build/build_C0/tmp-glibc/work/var_som_imx8qxp-wrs-linux/swupdate/2021.04-r0/git/suricatta/server_hawkbit.c : server_install_update : 1429 : Error processing update chunk named 'Test Hello', version 1.0, part bApp 

I've tried running "swupdate-ipc hawkbit" but the response is not too helpful "
swupdate-ipc gethawkbit
Sending: '' returned -1
Error: suricatta did respond with NACK.

Thanks in advance for any suggestions

SWUpdate has some channels based on UDS sockets that are created at the
startup or by systemd with CONFIG_SYSTEMD=y. As default, they are in
tml, and you should see just after starting the saemon /tmp/swupdateprog
and /tmp/sockinstctrl. If they are not there, nothing works.

You should first verify that sockets are there.

This should be :

ending: '' returned 0
Server returns ACK

Thank you - I didn't realize that the swupdate.socket was not running.   as soon as I started it, the /tmp/sockets appeared and everything worked!
