zypper-upgraderepo 1.2 is out
February 23rd, 2019 by
Fixes and updates applied with this second minor version improved and extended the main functions, let’s see what’s new.
If you are new to the zypper-upgraderepo plugin, give a look to the previous article to better understand the mission and the basic usage.
Repository check
The first important change is inherent the way to check a valid repository:
- the HTTP request sent is HEAD instead of GET in order to have a more lightweight answer from the server, being the HTML page not included in the packet;
- the request point directly to the repodata.xml file instead of the folder, that because some server security setting could hide the directory listing and send back a 404 error although the repository works properly.
Check just a few repos
Most of the times we want to check the whole repository’s list at once, but sometimes we want to check few of them to see whether or not they are finally available or ready to be upgraded without looping through the whole list again and again. That’s where the –only-repo switch followed by a list of comma-separated numbers comes in help.
–only-repo switch
All repo by default
The disabled repositories now are shown by default and a new column highlights which of them are enabled or not, keeping their number in sync with the zypper lr output. To see only the enabled ones just use the switch –only-enabled.
Table view
Report view
Beside the table view, the switch –report introduce a new pleasant view using just two columns and spanning the right cell to more rows in order to improve the number of info and the reading quality.
Report view
Other changes
The procedure which tries to discover an alternative URL now dives back and forth the directory list in order to explore the whole tree of folders wherever the access is allowed by the server itself. The side effect is a general improvement also in repo downgrade.
The output in upgrade mode is now verbose and shows a table similar to the checking one, giving details about the changed URLs in the details column.
The server timeout error is now handled through the switch –timeout which allows tweaking the time before to consider an error any late answer from the server itself.
Final thoughts and what’s next
This plugin is practically completed, achieving all the goals needed for its main purpose no other relevant changes are scheduled, so I started thinking of other projects to work in my spare time.
Among them, there is one I am interested in: bring the power of openSUSE software search page to the command line.
However, there are some problems:
- This website doesn’t implement any web API so will be a lot of scraping job;
- There are missing packages while switching from the global research (selecting All distribution) to the specific distribution;
- Packages from Packman are not included.
I have already got some ideas to solve them and did lay down several lines of code, so let’s see what happens!

zypper-upgraderepo-plugin is here
August 7th, 2018 by FabioMux
zypper-upgraderepo-plugin adds to zypper the ability to check the repository URLs either for the current version or the next release, and upgrade them all at once in order to upgrade the whole system from command line.
This tool started as a personal project when a day I was in the need to upgrade my distro quicker than using a traditional ISO image, Zypper was the right tool but I got a little stuck when I had to handle repositories: some of them were not yet upgraded, others changed slightly in the URL path.
Who knows how to Bash the problem is not exactly a nightmare, and so I did until I needed to make a step further.
The result is zypper-upgraderepo Ruby gem which can be integrated as a zypper plugin just installing the zypper-upgraderepo-plugin package.
Installing zypper-upgraderepo-plugin
Installing zypper-upgraderepo-plugin is as easy as:
- Adding my repo:
sudo zypper ar https://download.opensuse.org/repositories/home:/FabioMux/openSUSE_Leap_42.3/home:FabioMux.repo - Install the package:
sudo zypper in zypper-upgraderepo-plugin
How to use it
Sometime we want to know the status of current repositories, the command zypper ref does a similar job but it is primarily intended to update the repository’s data and that slow down a bit the whole process.
Instead we can type: $ zypper upgraderepo --check-current 
To know whether or not all the available repositories are upgrade-ready: $ zypper upgraderepo --check-next 
As you can see from the example above all the enabled repositories are ready to upgrade except for the OSS repo which has a slightly different URL.
`
The URL used in the openSUSE Leap 42.3
http://download.opensuse.org/distribution/leap/42.3/repo/oss/suse/
The suggested one for openSUSE Leap 15.0
http://download.opensuse.org/distribution/leap/15.0/repo/oss/
`
Let’s try again overriding the URL without make any real change: $ zypper upgraderepo --check-next \ --override-url 8,http://download.opensuse.org/distribution/leap/15.0/repo/oss/ 
Once everything is ok, and after performed a backup including all the repositories, it’s time to upgrade all the repository at once: $ sudo zypper upgraderepo --upgrade \ --override-url 8,http://download.opensuse.org/distribution/leap/15.0/repo/oss/
Conclusions
That’s all with the basic commands, more information is available in the wiki page of zypper-upgraderepo gem where all the commands are intended with the only use of the gem, but installing the plugin they are also available as zypper subcommands like shown above, also a man page is available as $ zypper help upgraderepo

wxRuby is now on BuildService
March 22nd, 2013 by FabioMux
I am happy to announce that i succeded in compiling wxRuby 2.0.1 on my Buildservice account and it is available to be installed in just one click for openSUSE 12.2 and 12.3.
wxRuby is an old but working library based on wxWidgets toolkit, till some day ago the dependency from SWIG 1.3.38 and some small errors raised during the manual compilation, made the use of this library the worst nightmare for beginners who was looking for a fast approach to GUI based programming in Ruby.
After some day spent to investigate about a possible upgrade of the SWIG dependency to the current 2.0 version, i produced some patches to fix this and the other annoying compiling errors, and finally, thanks to the Buildservice infrastructure, a wxRuby RPM compiled from sources with the relative patches are now availables for all openSUSE users!
As far i googled this should be the first distro to have a precompiled and working wxruby gem among its repositories (being compiled from sources the gem is generated for 32 and 64 bits architecture from Buildservice itself), so Rubyists take a look on software.opensuse.org, select the package coming from my home project account and enjoy!

Recompiling wxRuby
September 4th, 2010 by FabioMux
Who uses Ruby might be interested to try this interesting multiplatform library that allows the development of GUI (Graphic User Interface) with a considerable visual impact and compatible with the three most popular Operating Systems: Linux (via GTK) Windows (with Native controls) and OSX (via Aqua).

Some KDE 4 tips you should know
August 13th, 2009 by FabioMux
KDE 4 is definitively my daily desktop environment, although it’s not yet mature like the 3.5.x branch i consider it enough stable and usable, but sometime the default settings and the few time available, don’t help us to appreciate it, so let’s resume some little tip for beginners that feel lost with everything new and don’t want waste their time.
