Failed to start Raise network interfaces after dist-upgrade

Support
1

Hello. I have two Workstations. On the second Workstation I did upgrade-nonroot and installed a huge upgrade (it seems like it’s a new version of Whonix).

But after installation completed, I’ve done autoremove and then rebooted. And I see ERROR: Failed to start Raise network interfaces on boot screen. Even though this error appears, Internet works fine.

I have the following systemd log:

systemd[1]: Starting Raise network interfaces...
ifup[623]: RTNETLINK answers: File exists
ifup[578]: ifup: failed to bring up eth0
systemd[1]: networking.service: Main process exited, code=exited, status=1/FAILURE
systemd[1]: networking.service: Failed with result 'exit-code'.
systemd[1]: Failed to start Raise network interfaces.

I typed ip a and I noticed strange things: both 10.152.152.11 and 10.152.152.12 hardcoded adresses are binded:

inet 10.152.152.12/18 brd 10.152.191.255 scope global eth0
       valid_lft forever preferred_lft forever
inet 10.152.152.11/18 brd 10.152.191.255 scope global secondary eth0

That is wrong! 10.152.152.11 should belong only to the first Workstation, not to the second!!!

On /etc/network/interfaces.d/30_non-qubes-whonix I incremented address number

iface eth0 inet static
       ## Increment last octet of address
       ## on optional additional workstations.
       ## IP HARDCODED unfortunately.
       address 10.152.152.12
       netmask 255.255.192.0
       gateway 10.152.152.10

       ## Out commented.
       ## For what do we require the network and broadcast
       ## instances anyway?
       #network 192.168.0.0
       #broadcast 192.168.0.255

Well, I need help. How to solve the problem Failed to start Raise network interfaces ?

Well, I found out
/etc/network/interfaces.d/30_non-qubes-whonix.dpkg-dist file near the main
/etc/network/interfaces.d/30_non-qubes-whonix

Well, I noticed:

iface eth0 inet static
       ## Increment last octet of address
       ## on optional additional workstations.
       ## IP HARDCODED unfortunately.
       address 10.152.152.11
       netmask 255.255.192.0
       gateway 10.152.152.10

       ## Out commented.
       ## For what do we require the network and broadcast
       ## instances anyway?
       #network 192.168.0.0
       #broadcast 192.168.0.255

There on that file. Should I just delete
/etc/network/interfaces.d/30_non-qubes-whonix.dpkg-dist

And restart networking service? I need help. Thank you.

Delete /etc/network/interfaces.d/30_non-qubes-whonix.dpkg-dist.

sudo rm /etc/network/interfaces.d/30_non-qubes-whonix.dpkg-dist
