HPLIP

Running "sudo hp-setup" changed permission of other applications

Asked by Antonio Costantino

After I installed the HP LaserJet P1105 with "sudo hp-setup", KGpg and wicd were behaving strangely--not working.

Indeed, after many-many-many readings from forums and so, I discovered that owner and user of /home/antonio/.gnupg/pubring.gpg were changed to root, causing KGpg not to read my personal encryption key (meanwhile, a public key from HP was added).

Wicd was unable to start. Reading the log, I saw that /etc/wicd/wired-settings.conf was badly formatted. Moreover, manager-settings.conf, wired-settings.conf and wireless-settings.conf were all made readable only to root--making wicd requiring root password.

I know it can seem strange, but actually the same behavior was confirmed when I installed the same printer on my girlfriend's laptop (we're both using karmic fully updated--only security and recommended updates).

1) How is it possible for hp-setup to mess with other applications' permissions?

2) What's the right way to run hp-setup? Just as user, sudo hp-setup (recommended on hplip website) or kdesudo hp-setup?

3) How can I be sure it didn't mess with more difficult stuff to be discovered?

Thanks for your help,
Antonio

Note: hp-check can be run in three modes:
1. Compile-time check mode (-c or --compile): Use this mode before compiling the HPLIP supplied tarball (.tar.gz or .run) to determine if the proper dependencies are
installed to successfully compile HPLIP.
2. Run-time check mode (-r or --run): Use this mode to determine if a distro supplied package (.deb, .rpm, etc) or an already built HPLIP supplied tarball has the
proper dependencies installed to successfully run.
3. Both compile- and run-time check mode (-b or --both) (Default): This mode will check both of the above cases (both compile- and run-time dependencies).

Please do not run hp-setup as root. You should run it as non-root.
Will have a look the permission changes when run as root.

According to your answer, you should change the following page on the HP website:
http://hplipopensource.com/hplip-web/install/manual/hp_setup.html

I would really appreciate if you let me know if hp-setup may have changed other permissions of which I'm unaware.
