advligorts-rcg did not install on debian 11
At MIT on m1boot, postinstall script had an error that tr had an extra argument 'b'. This is not the exact wording.
I looked into the postinstall script. There is a tr command like tr [A-Z] [a-z]
changing the case of some text. This is in a code branch triggered by the existence of SITE and IFO environment variables.
I was able to get the package to install by unsetting these variable first. It's not clear what's wrong with the command.
