Configuring Net, Packet Write Wait - Broken pipe

OS : Debian 9
Virtualmin : Latest
VPS Core : 1

Hello all,
I bought a new low ram VPS with 1GB RAM for dev. However, when installing Virtualmin I get this error at the final stage.

Do a web or forum search howto change setup part to have more minimal installation

Also before make a swap file…

and take care of settings network and firewall related things

OYEA hmm for DEV then nog good idea having low memory box, while then if errors you don’t know related to low specs… :wink:

That is while on port 443:

EDIT THINK MY FAULT HERE sorry: > Dieser Server konnte nicht nachweisen, dass es sich bei ihm um handelt. Das Sicherheitszertifikat stammt von . but on dns it also has DNS-naam

So could also be on your site that can not handle that ssl encryption , or the port there , curl or whatever used to get the data

Check to be sure it i from right ip resolving from your box

That error i quoted is strange on first call in edge, after i did the call to it was there then ok on to

First of all, I want to apologize for being stupid and not really taking notice of the supported OS. I can see that Virtualmin no longer supports Debian 9. Thanks to my hosting customer service “Not Contabo” another provider “Alexhost”. advice me to check on a supported OS. “They already knew about this” LOL

So I installed Debian 10 and the SSL issue popup, I followed what joe mentioned in his post.


Found this post and on this @Joe mentioned that I need to do an update

So I did
apt update && apt upgrade

Boom I was able to run the installation without the error.

Now will wait and see if I get success result

I got the same error “Configuring Net” I contacted the support and they are going help me install Virtualmin on Centos 7 but not Debian 10 :grinning_face_with_smiling_eyes:

Okay that all being said it took them 1hr+ and still Virtualmin is not ready and when I asked them they replied: “Still in progress.”

Not possible cuz installation won’t take 1hrs+ :rofl: they are going through the same issue that I went through and now they are troubleshooting, trying to fix their servers. :face_with_hand_over_mouth:

So I’m going to assume this is a server-side issue and not a Virtualmin.

Apologize for all the mixup. sometimes you need to hustle to find out what is really going on. :grinning: :v:

Not gonna bang my head on this :sunglasses:
