APT Repository not working (signatures invalid)

[Christopher_G_2]

I'm using the steps from here and getting a GPG error: installing-intel-free-libs-and-python-apt-repo

Here are the steps I'm doing:

1. docker run -it -rm ubuntu:18.04 bash
2. apt-get update
3. apt-get install -y --show-progress curl gnupg
4. curl https://apt.repos.intel.com/intel-gpg-keys/GPG-PUB-KEY-INTEL-SW-PRODUCTS-2019.PUB | apt-key add -
5. echo 'deb https://apt.repos.intel.com/mkl all main' > /etc/apt/sources.list.d/intel-mkl.list
6. apt-get update

Here is the error (note: it is happening with the TBB repository as well:

Seems to be fixed now. Removing the old key and installing the new one does the trick:

sudo apt-key del 1911E097
wget -O- https://apt.repos.intel.com/intel-gpg-keys/GPG-PUB-KEY-INTEL-SW-PRODUCTS-2019.PUB | sudo apt-key add -

# curl https://yum.repos.intel.com/intel-gpg-keys/GPG-PUB-KEY-INTEL-SW-PRODUCTS-2023.PUB | apt-key add -

I'm getting this error again while trying to install MKL v2020.0-088. I'm using this script to install MKL when building Docker image.

I started getting the following error yesterday:

Err:8 https://apt.repos.intel.com/mkl all InRelease 
The following signatures were invalid: EXPKEYSIG ACFA9FC57E6C5DBE Intel(R) Software Development Products

W: GPG error: https://apt.repos.intel.com/mkl all InRelease: The following signatures were invalid: EXPKEYSIG ACFA9FC57E6C5DBE Intel(R) Software Development Products
E: The repository 'https://apt.repos.intel.com/mkl all InRelease' is not signed.

The key https://apt.repos.intel.com/intel-gpg-keys/GPG-PUB-KEY-INTEL-SW-PRODUCTS-2019.PUB  is used.

Having same issue as @EugKar. There is a new GPG key file to download, but MKL needs to be re-signed with a not expired key still.

[Stijn_Schildermans]

Exact same issue here.

It worked for me:

from:

RUN wget https://apt.repos.intel.com/intel-gpg-keys/GPG-PUB-KEY-INTEL-SW-PRODUCTS-2019.PUB
RUN apt-key add GPG-PUB-KEY-INTEL-SW-PRODUCTS-2019.PUB
RUN sh -c 'echo deb https://apt.repos.intel.com/mkl all main > /etc/apt/sources.list.d/intel-mkl.list'

to:

RUN wget https://apt.repos.intel.com/intel-gpg-keys/GPG-PUB-KEY-INTEL-SW-PRODUCTS.PUB 
RUN apt-key add GPG-PUB-KEY-INTEL-SW-PRODUCTS.PUB
RUN sh -c 'echo deb https://apt.repos.intel.com/mkl all main > /etc/apt/sources.list.d/intel-mkl.list'

Simple remove "-2019"
