CentOS7 build : hash mismatch

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 ?
