Failed to fetch https://ppa1.novemberain.com/rabbitmq/rabbitmq-erlang/deb/ubuntu/dists/focal/main/binary-i386/Packages

I ran sudo apt update and I found thatt this url is invalid, so my rabbitmq-server cannot be updated. Is there anything I can do to fix this?

The mirror does not have i386 (32-bit) packages. We never produced them or published for 32-bit. Maybe Cloudsmith itself indexes arch-neutral packages for i386 but Erlang Debian packages are not arch-neutral (while RabbitMQ Debian packages are).

Use a 64-bit machine.

Compare

curl https://ppa1.novemberain.com/rabbitmq/rabbitmq-erlang/deb/ubuntu/dists/focal/main/binary-i386/Packages

to

curl https://ppa1.novemberain.com/rabbitmq/rabbitmq-erlang/deb/ubuntu/dists/focal/main/binary-amd64/Packages

which does return a package index file.

Thanks! I think this is the problem for me. I'm indeed using a 64-bit devise, not sure how this url was generated. So how can I change the configuration so that sudo apt get fetches packages via the correct url? I checked rabbitmq.list file but I did not find the link the url for 32-bit so I don't know how to change it to the one for 64-bit

I was able to work around this issue by adding arch=amd64 to all the deb lines lines in /etc/apt/sources.list.d/rabbitmq.list. For example, this line:

deb [signed-by=/usr/share/keyrings/rabbitmq.E495BB49CC4BBE5B.gpg] https://ppa1.novemberain.com/rabbitmq/rabbitmq-erlang/deb/ubuntu jammy main

Would change to this line:

deb [arch=amd64 signed-by=/usr/share/keyrings/rabbitmq.E495BB49CC4BBE5B.gpg] https://ppa1.novemberain.com/rabbitmq/rabbitmq-erlang/deb/ubuntu jammy main
