This question already has an answer here:

I'm looking for suggestions on how to troubleshoot this.

I am running VMWare 6.5 on a Supermicro blade server about 2000 miles away, with Ubuntu 16.04.3 LTS installed as a VM.

I know that the datacenter server is able to download at a speed of at least 200 megabit/sec.

I am trying to install Oracle Java 8. During the install, the download pauses for a long time.

@ubuntu:~$ sudo apt-get install oracle-java8-installer

And there it will sit, but it won't fail. It does ultimately succeed:

Oracle JDK 8 installed

#####Important########
To set Oracle JDK8 as default, install the "oracle-java8-set-default" package.
E.g.: sudo apt install oracle-java8-set-default
On Ubuntu systems, oracle-java8-set-default is most probably installed
automatically with this package.

Everything else I do with this system seems to be working fine. I did a remote copy of about 100 gigabytes via SFTP to this virtual machine, and that did not hang like this.

Is there some way to see what is going on with the ubuntu hardware or network, when it hangs like this? Would I need to do a packet capture to resolve this?

I have experienced a similar issue and resolved it by changing the MTU. try changing it to something like 1451 or less.

how do I change default MTU from 1500 to 9000 for lxdbr0 for containers created using LXD?
