### Bug Description Building the provided rockcraft.yaml fails. The problem happens specifically because of the "https" `url`. If I change it to "http", _or_ if I change the base to 22.04, it works. As part of diagnosis I tried running a `public.ecr.aws/ubuntu/ubuntu:20.04` container; I can `wget` that url just fine. ### To Reproduce Use the `rockcraft.yaml` provided, then `rockcraft -v` ### Environment rockcraft from edge (`latest/edge: 0+git.3c49911 2023-08-14 (980)`) ### rockcraft.yaml ```shell name: my-rock-name base: ubuntu:20.04 version: '0.1' summary: Test description: Test license: GPL-3.0 platforms: amd64: package-repositories: - type: apt components: [main] suites: [focal] key-id: 9FD3B784BC1C6FC31A8A0A1C1655A0AB68576280 url: https://deb.nodesource.com/node_14.x parts: my-part: plugin: nil overlay-packages: [hello] ``` ### Relevant log output ```shell 2023-08-14 10:06:24.222 :: 2023-08-14 13:06:19.406 [pid=619] chroot to PosixPath('/root/overlay/overlay') 2023-08-14 10:06:24.222 :: 2023-08-14 13:06:19.406 Executing: ['apt-get', 'update'] 2023-08-14 10:06:24.222 :: 2023-08-14 13:06:19.529 :: Ign:1 https://deb.nodesource.com/node_14.x jammy InRelease 2023-08-14 10:06:24.222 :: 2023-08-14 13:06:19.610 :: Err:2 https://deb.nodesource.com/node_14.x jammy Release 2023-08-14 10:06:24.222 :: 2023-08-14 13:06:19.610 :: Certificate verification failed: The certificate is NOT trusted.
