RPM installation of 3.21.4 fails on CentOS 7

Asked by Ross Palmer

I'm trying to install hplip 3.21.4 on CentOS 7 using the RHEL7 RPM. This fails:
# rpm -i hplip-3.21.4-RHEL7-x86_64.rpm
error: Failed dependencies:
 libImageProcessor.so()(64bit) is needed by hplipfull-3.21.4-0.x86_64
 libImageProcessor.so(VERS_1.0)(64bit) is needed by hplipfull-3.21.4-0.x86_64

However libImageProcessor.so is supplied by the hplip package itself so why is it listed as a dependency?

Installing using the .run file gives the same error.

As it happens the system has /usr/lib64/libImageProcessor.so()(VERS_1.0) present from
an earlier version of hplip but the dependency check doesn't pick that up.

So how can I get hplip 3.21.4 to install?

Thanks

Hi Ross. I was about to open the same question as I discovered the same thing. To get it to install, the following link works, but it does not allow for the use of 'yum' (which is preferred) since there is no --nodeps or --force option:

On a system where I had forced the installation of hplipfull-3.21.2 with the rpm command, I later tried to update with yum, and that failed even though the libImageProcessor.so file is already on the system:

root@server1:/root> ls -l /usr/lib64/libImageProcessor.so
lrwxrwxrwx 1 root root 38 Jun 2 15:28 /usr/lib64/libImageProcessor.so -> /usr/lib64/libImageProcessor-x86_64.so
root@server1:/root> ls -l /usr/lib64/libImageProcessor-x86_64.so
-rwxr-xr-x 1 root root 4646308 May 4 23:58 /usr/lib64/libImageProcessor-x86_64.so

Checking with rpm, the /usr/lib64/libImageProcessor-x86_64.so file is provided by hplipfull:

root@server1:/root> rpm -qif /usr/lib64/libImageProcessor-x86_64.so

Description :
The HP Linux Imaging and Printing (HPLIP) system

driver solution. HPLIPLITE provides support for print and scan only.
HPLIPFULL provides support for print, scan, fax and toolbox.

Please note, this is after I'd run the upgrade with 'rpm --force --nodeps -Uvh /path/to/rpm'. This behavior during the installation/upgrade via rpm and yum would seem to indicate some sort of circular dependency, or a pathing issue where the package manager is looking in the wrong place when checking dependencies. The /usr/lib64 location might be the issue if the package is checking /usr/lib, for example. This is just a guess on my part. Any insight from others on this?

Thanks George, the link you provided works though obviously it skips all the dependency checks (of which there are 50).
However my printer and scanner are working so fingers crossed its all OK.

From the link it seems this has been a known problem since at least 2018. Maybe it needs to be raised as bug rather than a question?
