CentOS7 build : hash mismatch

[nyue]

I followed the instruction to build via the

env ARCH=x86_64 bash ci/build.sh 

However, right at the end, there was an error about hash mismatch

Embedding ELF...
Marking the AppImage as executable...
Embedding MD5 digest
Success

and there was no output written to the out/ directory

Anyone else encountered this before ?

It's coming from this test:
