net-print/hplip-3.11.10: setting by hp-setup fails on installing printer plugin when /tmp is mounted with noexec (Permission denied)

[cyberbat]

I have HP LaserJet 1022. When I run hp-setup it says that it would be better
for me to install binary plugin for my printer. When I agree it download it but
fails to run.

When I download and run ./hplip-3.11.10-plugin.run manualy I got:
Verifying archive integrity... All good.
Uncompressing HPLIP 3.11.10 Plugin Self Extracting
Archive.........................................
./hplip-3.11.10-plugin.run: line 395: ./hplip-plugin-install: Permission denied

Seems that it extracts files somewhere to /tmp/ (mounted with noexec) and fails
to run.

After mount -o remount,exec /tmp everything is ok and my printer begin to work.
I can remount /tmp noexec after installing since it need not runing anything
from /tmp.

Hi,

Please run the command "hp-check -t" from terminal and post its output here.
To install plug-in files you need to have superuser privilege . You need to run command : su -c "hp-plugin" to install the plugin files.

Goutam, I know that I should start plugin-installer from root. I'm starting hp-setup from root. And the problem is, as I've figured, that my /tmp directory is placed on separate partition, mounted with noexec option. Setting noexec on world writable places is good way to do.

I think plugin should extract files to user's home directory if it wants to execute them or at least it should message user, that /tmp/ is mounted with noexec and it would fail.

Thanks you for clearing me on that. Will take a look at it.
