[mfrener]

Have you edited ibgateway-1010-standalone-linux-x64.sh.sha256?

14 0.819 sha256sum: 'ibgateway-1010-standalone-linux-x64.sh'$'\r': No such file or directory means the line on ibgateway-1010-standalone-linux-x64.sh.sha256 ends with CLRF (DOS), but should be LF (UNIX), so convert to UNIX line-end if you have edited.

If not, I'm wondering where this comes from because the 1010-standalone-linux-x64.sh.sha256 has LF for me and build works, same it does on CI.

@mfrener I did not edit the file, but faced a similar issue with CLRF in some of the bash scripts. I will do the same with the SHA256 file and let you know.

[marvin-garcia]

I fixed the CLRF for the checksum file and everything worked. Thanks for the tip!
