Rats. During the first operation of my newly-installed intranet Twiki, I got the following message:
During save of file TWiki.TWikiPreferences an error was found by the version control system. Please notify your TWiki administrator. /usr/bin/ci -q -l -m'none' -t-none -w'guest' /var/www/twiki/data/TWiki/TWikiPreferences.txt 2>&1 ci: /var/www/twiki/data/TWiki/TWikiPreferences.txt,v: Permission denied Go back in your browser and save your changes locally.
Attempts to resolve the problem with perl, chmod and chown only compounded the problem until the Twiki wouldn’t even recognize its own configuration. Time to walk away and try it again another time. Sheesh.
