Why does blocksat-cli deps tbs-drivers change the network connections of the VM?

[VDelport]

I am trying to install blocksat-cli usb on a VM (Virtual Box) and the guest system Ubuntu.

While I am running blocksat-cli deps tbs-drivers the internet connection is available:

ip a
1: lo: <LOOPBACK, UP, LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN group default qlen 1000
link / loopback 00: 00: 00: 00: 00: 00 brd 00: 00: 00: 00: 00: 00
inet 127.0.0.1/8 scope host lo
valid_lft forever preferred_lft forever
inet6 :: 1/128 scope host
valid_lft forever preferred_lft forever
2: enp0s3: <BROADCAST, MULTICAST, UP, LOWER_UP> mtu 1500 qdisc fq_codel state UP group default qlen 1000
link / ether 08: 00: 27: 04: 4a: 12 brd ff: ff: ff: ff: ff: ff

3: dvb0_0: <BROADCAST, MULTICAST, NOARP, UP, LOWER_UP> mtu 4096 qdisc fq_codel state UNKNOWN group default qlen 1000

link / ether 00: 22: ab: c0: 57: b0 brd ff: ff: ff: ff: ff: ff

After the blocksat-cli deps tbs-drivers and reboot I can connect to the TBS5927, but an internet connection is no longer possible:

ip a
1: lo: <LOOPBACK, UP, LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN group default qlen 1000
link / loopback 00: 00: 00: 00: 00: 00 brd 00: 00: 00: 00: 00: 00

valid_lft forever preferred_lft forever
inet6 :: 1/128 scope host
valid_lft forever preferred_lft forever
2: enp0s3: <BROADCAST, MULTICAST> mtu 1500 qdisc noop state DOWN group default qlen 1000
link / ether 08: 00: 27: 04: 4a: 12 brd ff: ff: ff: ff: ff: ff

Hi @VDelport ,

Command blocksat-cli deps tbs-drivers does not change the network connections. Perhaps you lost the connection simply due to rebooting?

In any case, the subcommands of blocksat-cli deps support dry-run mode, through which you can see all the shell commands that are executed without actually executing them. For the TBS drivers, you can check:

blocksat-cli deps --dry tbs-drivers

In contrast to the TBS driver installation step, note that command blocksat-cli usb config does create new network interfaces for the DVB-S2 adapters. On Ubuntu 18.04+, the CLI creates network interfaces with static IP addresses using Netplan. However, the CLI does not remove any existing network interface or connection.

Again, you can check all the steps that are executed without actually executing them. This is actually the default on command usb cfg when executed by a non-root user. Assuming that's your case, just run it like so:

blocksat-cli usb cfg

If the changes work for you and you want to apply them, you can simply run as root (i.e., with sudo, as given below). If not, you can adapt the steps and run them manually.

sudo blocksat-cli usb cfg
