I cannot connect via SSH

Running the following commands from your Linode will give you some more information about the problem:

systemctl status networking.service -l

sudo ifdown -a && sudo ifup -a

Recently, we’ve seen a large number of these issues caused by a broken Sendmail update. If you use Sendmail, you will likely come across an output similar to the following:

/etc/network/if-up.d/sendmail: 44: .: Can't open /usr/share/sendmail/dynamic

run-parts: /etc/network/if-up.d/sendmail exited with return code 2

The sendmail issue can usually be resolved by running the following two commands:

sudo mv /etc/network/if-up.d/sendmail ~

ifdown -a && ifup -a

Thanks for this. I also just ran into this same issue and moving the /etc/network/if-up.d/sendmail directory worked for me.

Sendmail appears to still be working even with this entire directory removed…is it entirely extraneous?

Hey damon, I do believe this is an extraneous folder and normally doesn't impact the usage of sendmail. From my understanding, this is the result of a broken sendmail update somewhere along the way or sendmail not cleaning itself up after a removal.
