Issues with Extensible SDK: Checksum Mismatch and Sstate Warnings

Hello Yocto Community,
I've encountered some issues while using the Extensible SDK (eSDK) and would appreciate any guidance or insights you might have. Here are the details of the errors:

Sstate Warning:
WARNING: You are using a local hash equivalence server but have configured an sstate mirror. This will likely mean no sstate will match from the mirror. You may wish to disable the hash equivalence use (BB_HASHSERVE), or use a hash equivalence server alongside the sstate mirror.

Checksum Mismatch for Boost:
WARNING: Checksum mismatch for local file /opt/Yocto_ESDK/Yocto_ESDK_x86/downloads/boost_1_74_0.tar.bz2
Cleaning and trying again.
WARNING: Renaming /opt/Yocto_ESDK/Yocto_ESDK_x86/downloads/boost_1_74_0.tar.bz2 to /opt/Yocto_ESDK/Yocto_ESDK_x86/downloads/boost_1_74_0.tar.bz2_bad-checksum_5447ae595623f7b8260e93a402896c57282df45d6dcdf6950155f110f7eb55a7
WARNING: Failed to fetch URL https://dl.bintray.com/boostorg/release/1.74.0/source/boost_1_74_0.tar.bz2, attempting MIRRORS if available

I have ensured that Boost is included in the IMAGE_INSTALL of the image I'm using. Given this, I'm puzzled as to why Boost is not part of the eSDK sysroot. Shouldn't all the libraries and headers specified in the image be included in the eSDK sysroot? How to fix those issues ?

Best regards,
Nicolas
