Bug when importing backup

[cr1stt0f3r]

Hello good afternoon.

I am migrating a system in operation from 2.2.5 to 2.5.0.

I tried to do the update in the form of a ladder but it didn't work.

At this point, I made a direct jump to 2.5.0!

But, in the squid configuration a network card appears that does not exist .. nor deactivates in the old system as in the new one.

Could you give me ideas on how to delete it?!
