[Qgis-user] Issues to install QGIS on RedHat 6

Wed Jun 10 12:40:02 PDT 2015

Hi,

I managed to install 2.8 on Red Hat 7. It took me a while to find all dependencies but I made it.

Thank you for your support.

This is the error.

There is a small issue of launching Python Console from QGIS.
I got this error:
Couldn't load plugin 'processing' from ['/usr/share/qgis/python', '/home/qgisosr/.qgis2/python', '/home/qgisosr/.qgis2/python/plugins', '/usr/share/qgis/python/plugins', '/usr/lib64/python27.zip', '/usr/lib64/python2.7', '/usr/lib64/python2.7/plat-linux2', '/usr/lib64/python2.7/lib-tk', '/usr/lib64/python2.7/lib-old', '/usr/lib64/python2.7/lib-dynload', '/usr/lib64/python2.7/site-packages', '/usr/lib64/python2.7/site-packages/gtk-2.0', '/usr/lib64/python2.7/site-packages/wx-2.8-gtk2-unicode', '/usr/lib/python2.7/site-packages', '/home/qgisosr/.qgis2//python', '/usr/share/qgis/python/plugins/fTools/tools']

Subject: Re: [Qgis-user] Issues to install QGIS on RedHat 6

After checking again, I realized that I originally did not compile any version after 2.0.1 because of the fact that the Qt version on RHEL 6 is 4.6. Newer QGIS versions require at least Qt 4.7 (actually even the 2.0.1 release has been modified in order to be able to run with Qt 4.6).

It would certainly be possible to provide QGIS for RHEL 6 with one of the following options:

 * Patch the QGIS code to remove post-Qt-4.6-features (would need to be re-done for every QGIS release)
 * Create Qt 4.8 packages for RHEL (would replace Qt 4.6, hence break other apps)
 * Create Qt 5 packages for RHEL (requires building some dependencies once and optionally evaluating the status of PyQGIS for Qt5 if plugins are required)

Best regards,
Matthias

Hi,

There was never a release for 6Workstation and the last release for 6Server was available for 2.0.1. I symlinked the 6Workstation now so you should be able to install 2.0.1 from there - but that's probably not what you need.

I am currently trying to create packages for 2.8.2. If it just works I will make them available ASAP. I am not totally aware of the status of all dependencies, so we will have to wait and see how much trouble there is.

Regards,
Matthias

Hi,

I have issue to install QGIS 2.8 on Linux RedHat 6.

First part: I installed ELGIS and EPEL using the instructions from: http://www.qgis.org/en/site/forusers/alldownloads.html#rhel-centos-scientific-linux

The following commands were successfully executed
sudo wget fedora.vitu.ch/EL/qgis.repo -P /etc/yum.repos.d/
sudo rpm --import http://fedora.vitu.ch/Fedora/RPM-GPG-Key-vitu

But the execution of the next one failed:
sudo yum update

I got this error:
http://fedora.vitu.ch/EL/6Workstation/x86_64/repodata/repomd.xml: [Errno 14] PYCURL ERROR 22 - "The requested URL returned error: 404"
Trying other mirror.
Error: Cannot retrieve repository metadata (repomd.xml) for repository: qgis. Please verify its path and try again

This command failed as well.
sudo yum install qgis qgis-python qgis-grass qgis-mapserver

It seems the issue has been reported on Apr 14 2014 but no solution was release. It seems the location http://fedora.vitu.ch/EL/6Workstation/x86_64/repodata/does not exist anymore or was changed and instructions were not updated.

Does anyone know a solution?

Thanks,
Marian
