[Fix] Supported OS checking change

[V33m]

Update: Read Update2 first, so you can see the whole output. As you can see from the log, lsb_release -sr does not give me any number, which it should.

Hi,

I see that you only look for the specific filename "Debian" etc, while it is common to use longer filenames such as "Debian GNU/Linux". So in my case, I get "Your system does not appear to be supported", while it is Debian 10 (buster) as seen below. This can easily be fixed by checking ID instead of name, checking the first 6 chars of "Debian *", using a wildcard or checking for filename "Debian GNU/Linux" specifically as for "Debian" etc for line 271 in rtinst.

/usr/local/bin/rtinst: line 271: [: -ge: unary operator expected
Debian GNU/Linux 10 (buster)
Only Ubuntu release 16 and later, and Debian and Raspbian release 9 and later, are supported
Your system does not appear to be supported
Check https://github.com/arakasi72/rtinst/wiki/Installing-on-Older-OS to see if it is supported by an earlier rtinst release

OS information:

user@hostname:~$ cat /etc/os-release
PRETTY_NAME="Debian GNU/Linux 10 (buster)"
NAME="Debian GNU/Linux"
VERSION_ID="10"
VERSION="10 (buster)"
VERSION_CODENAME=buster
ID=debian
HOME_URL="https://www.debian.org/"
SUPPORT_URL="https://www.debian.org/support"
BUG_REPORT_URL="https://bugs.debian.org/"

The simple fix in the meantime for my case was just to change the variables manually.

sed -i '/^\s*osname=*/ c\osname=Debian' /etc/rtinst/scripts/rtinst
sed -i '/^\s*relno=*/ c\relno=10' /etc/rtinst/scripts/rtinst

Update:
Hmm, this is odd as I see that you find osname with lsb_release -si, which gives me Debian when I run it. So, it shouldn't fail in the first place. I get another error, which is the following:
/usr/local/bin/rtinst: line 44: [: =: unary operator expected

Update2:
Here is full output with "set -e -x" added to rtinst:
