I know this is not the proper way to do it, but I worked around this issue by deleting the line for zlib1g in the file, package/requirements_check/requirements.lnxubuntu2004arm64.isc.

Looks like the instance is working fine, so I suspect there is something wrong with requirement checking in installation.

Thanks. But looks like zlib1g is already installed..

I was trying to install the preview version on Ubuntu 20.04.3 LTS  ARM64(in a VM on Mac M1).

But irisintall gave the the following error. Installing zlib1g-dev did not solve the problem. Could anyone suggest me what I was missing?


Your system type is 'Ubuntu LTS (ARM64)'.

zlib1g version 1 is required.
