apt update: Could not handshake: An unexpected TLS packet was received
Solution 1
Check if the proxy is also set for https. Since curl
is working with https, I assume, that somewhere a https_proxy
variable is set (e.g. ~/.bashrc
). apt
requires a proxy configuration in /etc/apt/apt.conf
or /etc/apt/apt.conf.d/
. You need to specify the proxy for all protocols:
# e.g. in file /etc/apt/apt.conf.d/05proxy
Acquire::http::proxy "http://192.168.0.1:3128/";
Acquire::https::proxy "http://192.168.0.1:3128/";
Acquire::ftp::proxy "http://192.168.0.1:3128/";
Also keep in mind, if the proxy configuration is only set for the sdnc-dev
user, you need sudo -E
to expose the environment to the root user.
Solution 2
I got the same error when using apt-get update
, with Ubuntu 20.04 LTS.
I have configured the proxy during the installation, in this way the proxy urls are in /etc/apt/apt.conf.d/05proxy
In my case I wrongly configured the proxy URL (for my organization) and need to edit 05proxy
and change https://proxy.mydom.it
to http://proxy.mydom.it
Wrong config:
Acquire::http::proxy "https://proxy.mydom.it:8080";
Acquire::https::proxy "https://proxy.mydom.it:8080";
Good config:
Acquire::http::proxy "http://proxy.mydom.it:8080";
Acquire::https::proxy "http://proxy.mydom.it:8080";
Turning https to http, in my case, fixed the TLS error

anddocker
) with myUbuntu 17.10 VM
running inVirtualBox
. The error I get isCould not handshake: An unexpected TLS packet was received
.The following are steps that I took when trying to add
docker
repository and the output. The same thing happened when I tried to addnodejs
as well.sdnc-dev@sdncdev-VirtualBox:~/tools/idea-IC-173.4674.33/bin$ curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo apt-key add - OK sdnc-dev@sdncdev-VirtualBox:~/tools/idea-IC-173.4674.33/bin$ sudo apt-key fingerprint 0EBFCD88 pub rsa4096 2017-02-22 [SCEA] 9DC8 5822 9FC7 DD38 854A E2D8 8D81 803C 0EBF CD88 uid [ unknown] Docker Release (CE deb) <[email protected]> sub rsa4096 2017-02-22 [S] sdnc-dev@sdncdev-VirtualBox:~/tools/idea-IC-173.4674.33/bin$ sudo add-apt-repository "deb [arch=amd64] https://download.docker.com/linux/ubuntu $(lsb_release -cs) stable" [sudo] password for sdnc-dev: sdnc-dev@sdncdev-VirtualBox:~/tools/idea-IC-173.4674.33/bin$ sudo apt update Ign:1 https://download.docker.com/linux/ubuntu artful InRelease Err:2 https://download.docker.com/linux/ubuntu artful Release Could not handshake: An unexpected TLS packet was received.

Here is the details of my setup:
VM: Ubuntu 17.10 VirtualBox 5.2.8 r121009 (Qt5.6.2) I am behind corporate proxy.
Does anyone know how to fix this?
