[Etherlab-users] Problem with running Etherlab and Ethercat Master

[Henrik Barie]

Hello Andreas,

thank you very much for the installation manual,

in /etc/sysconfig/ I only had an "ethercat" file but no "ethercat.conf"
I deleted "ethercat"

Ive had a problem with
KEYRING=/usr/share/keyrings/ethercat.gpg curl -fsSL 
https://download.opensuse.org/repositories/home:/bone11111:/branches:/science:/EtherLab/xUbuntu_22.04/Release.key 
| gpg --dearmor | sudo tee  "$KEYRING" >/dev/null

it said
tee: '': File or Directory not found

but it seems to be solved by typing sudo tee"$KEYRING"
(without any spaces between tee and "$KEYRING".

It executed without any messages.

after step 3. "sudo apt-get update"  I got an error message:

.....
W: GPG-Fehler: 
http://download.opensuse.org/repositories/home:/bone11111:/branches:/science:/EtherLab/xUbuntu_22.04 
./ InRelease: Die folgenden Signaturen konnten nicht überprüft werden, 
weil ihr öffentlicher Schlüssel nicht verfügbar ist: NO_PUBKEY 
A08216C4FF0D8EF7
N: Das Laden der konfigurierten Datei »main/binary-i386/Packages« wird 
übersprungen, da das Depot »https://esm.ubuntu.com/realtime/ubuntu jammy 
InRelease« die Architektur »i386« nicht unterstützt.

I searched for a solution to get the public key but the code/command I 
found was deprecated and didnt work.

I continued with step 4.
sudo apt-get install linux-headers-5.15.0-1020-realtime
which said:
....
0 aktualisiert, 0 neu installiert, 0 zu entfernen und 0 nicht 
aktualisiert.

but shouldnt it have changed something?

in step 5. the testmanager couldnt be found


I wasnt sure if the "ethercat"-file from 
/usr/local/share/etherlab/etc/sysconfig/ethercat has to be copied to 
/etc/sysconfig or if it should be an "etherlab.conf"-file that must be 
copied?

also after the intallation there was no new
/lib/modules/KERNELVERSION/ethercat - file, which I deleted before.

Sadly it still doesnt work properly, I guess the installation wasnt 
complete. Do you know how I can fix the errors that occurred?
