Docker build 'repository is not signed error' (Ubuntu jammy)

graph-tool
1

Hi, I see that a few people have already posted about similar errors since yesterday. I just wanted to add this here as the error we are getting is slightly different, but probably has the same root cause.

We have a docker build from the jammy base image that contains the following as part of a RUN command to install graph-tool:

      && echo -n 'deb [ arch=amd64 ] https://downloads.skewed.de/apt jammy main' >> /etc/apt/sources.list \
      && apt-key adv --keyserver keyserver.ubuntu.com --recv-key 612DEFB798507F25 \
      && apt-get -y update \ 
      && apt-get install python3-graph-tool=2.45 -y

Since the updates yesterday (1 April) we have started to receive the following error:

E: The repository 'https://downloads.skewed.de/apt jammy Release' is not signed.

Thank you in advance for looking into this for us - appreciate that it’s a lot of time and effort on your part to maintain the library.

This has been fixed.

Please refrain from posting multiple messages about the same problem — it’s not really helpful.

Thanks for fixing it quickly, my apologies for double posting as I misread the error logs from the previous post and didn’t realise that it was indeed the same error.

It was all fixed now. Thank you so much for your help, Tiago! Your time and effort were valuable for graph-tool!
