CUPS 1.4.3 500 internal server error spup100 [SOLVED]

Message

I had this error also in lucid, so it didn't seem to be restricted to spup.
Had a good look at posts about this error in the forum.

One thing that struck was that a loaded sfs could be the cause.
So I walked that road.
I unloaded (on the fly) the sfs's I have and when I unloaded google-earth 6.2.2074 the error went away and I could add a printer.

I could do my printing.

But as soon as I reloaded this sfs I got the error again and couldn't print either.

So now the question. How can I go from there to diagnose further.
I mounted the sfs to look inside, but I see nothing special.
In fact I don't really know what I have to look for.

Well in fact I got a reminder that it could be something with permissions and ownership.

I checked the directories in that sfs when mounted separately with those of the system. They correspond being rwx,r-x,r-x root root
I suppose this stands for 755 in the permissions.

As they correspond, it might be something else then?

If someone has an idea it's welcome.

Perhaps down in /var region.

Anyway have a good weekend

google-earth 6.2.2074

Could you please provide a link to this sfs package?

Well, the long WE has become a long week

But I have cured the issue.

I got the sfs from http://smokey01.com/stu90/lucid.puppy.p ... 2.2074.sfs

I mounted the sfs by clicking on it.

As stated before, I didn't see anything special about permissions.

So I created another directory and copied the mounted google-earth 6.2.2074 directory to it.
I then recreated a sfs from this.
When mounting this newly created sfs on the fly, the issue was gone.
I could add a printer.

I also could run google earth.

Here is the problem with the Google Earth SFS.

First, if you turn on the CUPS debug mode, the error message is "/usr/lib/cups/cgi-bin/admin.cgi - permission denied". Keep in mind that CUPS wants to run the web interface as the unprivileged user root:nobody.

Now go to /initrd and check the properties of the mount point used by the Google Earth SFS. The permissions are 700, instead of the usual 755. This loss of permission filters all the way down to the CUPS files and keeps the web interface from working.

Repacking the SFS file restores the correct permissions and everything works properly.

Imagine what these malformed SFS and DEB packages would do to the Fido user!

Thanks rcrsn51 for the explanation.
I saw that the permission was indeed 700 and when I tried to change it, it couldn't be changed. As the mounting point is a read-only one.

Therefor instinctively I did already the repackaging you recommended now.

I have a very similar problem using SFS-Load 1.2 with frugal Puppy 528.

When I loaded Java Runtime Environment using

SFS-jre-1.7.0.01-20111027.sfs from
http://www.smokey01.com/coolpup/javarun ... nment.html

it broke CUPS - I could not print from AbiWord and CUP's 'printers' and 'print jobs' pages returned 'Internal Server Error 500'

---

Unloading SFS-jre-1.7.0.01-20111027.sfs fixes the problem.

---

Inside the SFS are the dirs:-
opt
root
usr

How can I repackage to allow me to load SFS and use printer?

---

Is it possible SFS Load could check for this problem and use a work-a-round?

Click on this SFS package to mount it, then check the mount point. The ownership and permissions are all wrong.

It needs to be repackaged so it has root:root ownership and 755 permissions.

You should report this to smokey01.

How can I repackage to allow me to load SFS and use printer?

Copy the original SFS to a location with lots of space.

Code: Select all

unsquashfs SFS-jre-1.7.0.01-20111027.sfs
chown root:root squashfs-root
chmod 755 squashfs-root
mksquashfs squashfs-root newjre.sfs

Hi rcrsn1,

I thought I'd solved my problem but now loading

jre-1.7.0.01-20111027a.SFS in Puppy5.28 with SFS Load 1.1

doesn't seem to work.

I get the java control panel in the menu but it won't run

---

also I tried to make a k3b sfs work with printer by using the code above,

similarly I get k3b in the menu but has missing libs when run,

the original SFS works but break printing

see http://www.murga-linux.com/puppy/viewto ... 565#593565

any ideas?
