Installation manual network config fails with "x.x.x.x is not in contained in x.x.x.x/yy"
1) lsb_release -rd
Description: Ubuntu 20.04.1 LTS
Release: 20.04
2) Package version
Unknown. Whatever version is part of ubuntu-
3) What I expected
For valid manual network settings to work.
4) What happened instead
Manual network configuration fails saying:
"'xxx.xxx.17.114' is not contained in '255.255.254.0/23'"
With network settings:
Subnet: 255.255.254.0/23
Address: xxx.xxx.17.114
Gateway: xxx.xxx.16.1
Subnet certainly contains xxx.xxx.16.1 - xxx.xxx.17.254
We attempted to define /23 on Address instead, but that is not allowed.
I work for NASA GSFC and we're having to proceed without network and then manually edit /etc/netplan/*.yaml after install.
If this is an error on our part, can you please clarify what we were supposed to enter for subnet? Since Subnet line requires an entry in CIDR form with error "should be in CIDR form (xx.xx.xx.xx/yy)"
Manual network config works fine with:
