Running bbs-agent on Enigma2 Linux reciever

[MegaV0lt]

Do you think it is possible to get the bbs-agent running on Enigma2 Linux receivers.
I have on with OpenATV 7.6. Some specs so far:

CPU 1/4 (HiSilicon 3798MV200 - ArmV7):

Processor	: ARMv7 Processor rev 4 (v7l)
BogoMIPS	: 3170.30
Features	: half thumb fastmult vfp edsp neon vfpv3 tls vfpv4 idiva idivt vfpd32 lpae aes pmull sha1 sha2 crc32 
CPU implementer	: 0x41
CPU architecture: 7
CPU variant	: 0x0
CPU part	: 0xd03
CPU revision	: 4

Kernel 4.4.37, Python 3.13.12

I am not sure about the borg bin. There is no borg in the sources.But i found one in the net (1.4.0) that seems running on the box.
Where has it to be to be found by the agent?

There is no systemd on the box. It is operating via /etc/init.d scripts

I have put borg binary in /usr/bin/ and installed the agent. Had to execute bash without sudo because i get not found error. Looks good so far

I added repositories and backup plans but the backup failed with an error message:

Found out that there is DropBear SSH installed

I have converted the OpenSSH key to DropBear SSH key format using dropbearconvert openssh dropbear ssh_key.openssh ssh_key.dropbear

Directory now contains

Backup was executed and marked as completed ;-)

Thats some nice debugging. I am not sure the demand of adding this to Borg, but will see if it's fairly simple or not.

[MegaV0lt]

It is working so far. First backups are made. Only thing is the borg binary.
What happens when the agent installer does not find borg? Is it trying to install it? And when that fails?

I had downloaded a borg binary for armv7l manually and it is working.

And the Dropbear ssh required to convert the ssh key. That can be detected by the installer by checking ssh -V
