    Hi llvm packaging team!

I'm using your apt repository to install multiple versions of llvm (14, 16, 18) on Debian (unstable).
Since a few days I'm experiencing dependency conflicts when installing llvm from apt.llvm.org:
```
3.034 The following packages have unmet dependencies:
3.180  llvm-14 : Depends: llvm-14-linker-tools (= 1:14.0.6~++20230130095011+f28c006a5895-1~exp1~20230130215051.177) but it is not going to be installed
3.180            Depends: libcurl3-nss (>= 7.23.1) but it is not installable
3.180  llvm-16 : Depends: llvm-16-linker-tools (= 1:16.0.6~++20231112112722+7cbf1a259152-1~exp1~20231112112735.116) but it is not going to be installed
``` 

 Dockerfile:
 ```Dockerfile
FROM debian:unstable-slim

RUN apt-get update && apt-get install -y --no-install-recommends \
    curl \
    wget \
    ca-certificates \
    lsb-release wget software-properties-common gnupg

RUN wget -qO- https://apt.llvm.org/llvm-snapshot.gpg.key | tee /etc/apt/trusted.gpg.d/apt.llvm.org.asc
RUN add-apt-repository "deb http://deb.debian.org/debian experimental main"
RUN add-apt-repository "deb http://deb.debian.org/debian experimental main"
RUN echo "deb http://apt.llvm.org/unstable llvm-toolchain main" > /etc/apt/sources.list.d/llvm.list \
  && echo "deb http://apt.llvm.org/unstable llvm-toolchain-18 main" > /etc/apt/sources.list.d/llvm-18.list \
  && echo "deb http://apt.llvm.org/unstable llvm-toolchain-16 main" > /etc/apt/sources.list.d/llvm-16.list \
  && echo "deb http://apt.llvm.org/unstable llvm-toolchain-14 main" > /etc/apt/sources.list.d/llvm-14.list \
  && curl -fsSL --tlsv1.2 https://apt.llvm.org/llvm-snapshot.gpg.key | gpg --dearmor -o /usr/share/keyrings/llvm-archive-keyring.gpg

RUN apt-get update && apt-get install -y --no-install-recommends \
 llvm-14/llvm-toolchain-14 llvm-16/llvm-toolchain-16 llvm-18/llvm-toolchain-18
``` 

Can you reproduce this behavior?
Is there anything I'm doing wrong?
Did you change something in the packaging?
