OpenSuse - Can't install Rails: File not found on medium - ruby-on-rails

I'm trying to set up a Ruby on Rails environment within OpenSuse, but I've encountered a problem. When running sudo zypper install rubygem-railties-3_2 all I get is File '/repodata/repomd.xml' not found on medium 'http://download.opensuse.org/repositories/Banshee/12.1/'. So something seems to be wrong at their side.
Is there anyone who as a workaround for, or more info about, this problem?

When running the command $ sudo zypper up I was receiving a similar error:
File ... not found on medium http:// ...
Detailed error:
File './x86_64/libxkbcommon0-0.7.2-48.2.x86_64.rpm' not found on medium 'http://download.opensuse.org/repositories/KDE:/Qt5/openSUSE_Leap_42.3/'
The solution which worked for me was to run $ sudo zypper ref before running $ sudo zypper up

Obviously, you have setup an additional repository for Banshee for a very old opensuse version. Opensuse only keeps its repositories alive for the last two two releases to the current release. For this reason, you get this error. You can disable or remove the repositorium to resolve the error.
In order to install packages that are not part of the currently configured repositories, it is the easiest to use the one-click install available at https://software.opensuse.org/search .

How to install syndesis (stable) on minishift

I'm trying to install syndesis on minishift following the official guides.
Installed minishift on ubuntu, no issues. Next I've tried
./syndesis minishift --install. In the end it says I have to run local dev builds for sysdesis-server syndesis-ui, etc
./syndesis build --app-images but got some dependency errors
Run syndesis quickstart. All the pods are up except syndesis-server. It doesn't start due to error like UnknownHostException: syndesis-db in the migration bean
Also tried ./syndesis minishift --install --tag 1.8.12 to install stable version but not sure if I'm doing it right cause no success
Any help ?
Sorry for the late response. We moved to use an Operator to do the installation and it caused a bunch of installation issues. If you have minishift installed then on Linux or Mac you should be able to get Syndesis installed using
bash <(curl -sL https://syndes.is/start)
See also: https://github.com/syndesisio/syndesis-quickstarts/blob/master/README.md#3-install-syndesis
It uses the syndesis bash command line tool from (https://github.com/syndesisio/syndesis/blob/master/tools/bin/), so you can check out the code yourself too and run that using:
./.syndesis/bin/syndesis minishift --install --full-reset --nodev --open
and then you can explore other options to specify a tag if you want.
Hope this gets you going!
Cheers,

Ubuntu, shopsys install via composer, docker, still crashing

I wanna install shopsys via composer and docker, as is recommended.
https://github.com/shopsys/shopsys/blob/master/docs/installation/installation-using-docker-linux.md
I installed git, php-fpm (configured), postgres (configured), composer, docker, docker-compose.
sudo apt install git
sudo apt install php7.2-fpm
sudo apt install postgresql
sudo apt install composer
sudo apt install docker-ce
sudo apt install docker-compose
Everything ok.
I added my user to docker group.
sudo usermod -a -G docker $(whoami)
Ok.
Next I made folder /var/www/html/shopsys, created project shopsys via composer.
composer create-project shopsys/project-base --no-install --keep-vcs
cd project-base/
Then I run this in /var/www/html/shopsys/project-base.
./scripts/install.sh
Everything seems to be ok, until this.
[RuntimeException]
/var/www/html/vendor does not exist and could not be created.
I set rights to 777 for folder /var/www/html, and run it again, but same problem.
The I run this.
sudo composer install
It shows me this error.
....Exception\InvalidConfigurationException]
Invalid configuration for path "monolog.handlers.main": You can only use ex
cluded_http_codes/excluded_404s with a FingersCrossedHandler definition
In ScriptHandler.php line 294:
An error occurred when executing the "'shopsys:domains-urls:configure'" command:
In BaseNode.php line 319:
...\Exception\InvalidConfigurationException]
Invalid configuration for path "monolog.handlers.main": You can only use ex
cluded_http_codes/excluded_404s with a FingersCrossedHandler definition
...
etc., error is quite ugly.
Last error when i run script install.sh.
file_put_contents(/var/www/html/vendor/composer/installed.json): failed to open stream: Permission denied
But this folder does not exist.
ls: cannot access '/var/www/html/vendor/': No such file or directory
Just question, where could be the problem?
Is possible to download sources from some link, extract it, configure and display in web browser with easy way, for example as wordpress?
Thanks.
To solve problem with vendor:
It seems that your UID and GID is different than default 1000, that is set in docker-compose.yml for Linux by default.
To solve your issue you can continue by step 3 in https://github.com/shopsys/shopsys/blob/master/docs/installation/installation-using-docker-linux.md#3-set-the-uid-and-gid-to-allow-file-access-in-mounted-volumes
You found issue with installation script, I have created issue on GitHub.
To solve problem with Invalid configuration for path "monolog.handlers.main":
Currently there is problem with new minor version (3.4.0) of symfony/monolog-bundle that created BC break. There is already created issue about this problem and there is already merged fix in Shopsys master.
To solve problem in your project you have to add
"symfony/monolog-bundle": ">=3.4.0", in conflict section in your composer.json file and then run composer install again.
We are trying to answer questions on stackoverflow as soon as possible, but we also have Slack where is many users and you might get your question answered much faster.

Raspbian docker: Error response from daemon: cgroups: memory cgroup not supported on this system: unknown

I am new to docker, I plug my PI3 to test some stuff and I'm already facing an error, I can't figured that out myself.
So I freshly install raspbian and docker.
That's my install log
Then I try the classic hello-word test
and there is the log
It looks 17.11.0 has the problem.
Could you try to install the old one as below ?
$ sudo apt install docker-ce=17.09.0~ce-0~raspbian
Or wait for the fix.
(2017.12.5)
It looks 2017-11-29-raspbian-stretch has same issue. To avoid upgrading by apt upgrade, Do: sudo apt-mark hold docker-ce.
And unhold when it fixes.
Another solution is to add cgroup_enable=memory cgroup_memory=1 in /boot/cmdline.txt at the end of the line and reboot.

asdf-erlang doesn't install man pages

I am using asdf + asdf-erlang as my version manager for Erlang. All seems to be working fine, except that typing erl -man mnesia results in No manual entry for mnesia.
I have installed all dependencies mentioned on the asdf-erlang github page. I have also installed xsltproc and fop. Unfortunately "man" folder located under ~/.asdf/installs/erlang/18.3/lib/erlang/erts-73/ is empty. I haven't found man pages being generated elsewhere.
I was trying to locate build log, but I was not successful with that either.
I am using 64bit Ubuntu 16.10 & 16.04.
OK. I finally managed to resolve the issue:
Go to https://www.erlang.org/downloads/ and download manpages for the version(s) of Erlang you have installed using asdf (so for 18.3 you're looking for: http://erlang.org/download/otp_doc_man_18.3.tar.gz)
Copy man folder with its content (extracted from the archive) to ~/.asdf/installs/erlang/<version>/lib/erlang/. After doing so, you should have .~/asdf/installs/erlang/<version>/lib/erlang/man containing man1, man3, man4, man6, man7 (and each of those folders should have some manpages in it).
Repeating steps above for all the versions installed using asdf, allows you to use manpages for specific version of Erlang you are using at the moment.
looks like erlang-manpages are not included in the asdf-erlang since you are using ubuntu i would suggest you add Erlang Solutions repository to your system, call the following commands:
wget https://packages.erlang-solutions.com/erlang-solutions_1.0_all.deb
sudo dpkg -i erlang-solutions_1.0_all.deb
sudo apt-get update
then install erlang-manpages:
sudo apt-get install erlang-manpages
you could also install erlang-doc — HTML/PDF documentation
sudo apt-get install erlang-doc
check this page for more information
The man path in #MaciekTalaska 's answer seems not correct, it does not work at all, for erlang 18.3.
After reading ASDF's activate script(), here's one statement:
_KERL_MANPATH_REMOVABLE="$HOME/.asdf/installs/erlang/18.3/lib/erlang/man:$HOME/.asdf/installs/erlang/18.3/man"
Therefore, you just need to:
Go to https://www.erlang.org/downloads/ and download manpages for the version(s) of Erlang you have installed using asdf (so for 18.3 you're looking for: http://erlang.org/download/otp_doc_man_18.3.tar.gz)
Copy man folder with its content (extracted from the archive) to $HOME/.asdf/installs/erlang/${version}, but not $HOME/.asdf/installs/erlang/${version}/lib/erlang/ (in fact, there isn't a folder named erlang under lib).
