I try to follow the guide bellow to install .net core on my raspberry pi 3:
https://www.microsoft.com/net/core#debian
The script told me to install below:
dotnet_install: Error: Unable to locate libunwind. Install libunwind to continue
dotnet_install: Error: Unable to locate gettext. Install gettext to continue
i install them using apt-get install, and everything fine:
sudo apt-get install libunwind-dev
sudo apt-get install gettext
but no luck, when i run below :
sudo curl -sSL https://raw.githubusercontent.com/dotnet/cli/rel/1.0.0/scripts/obtain/dotnet-install.sh | bash /dev/stdin --version 1.0.0-preview1-002702 --install-dir ~/dotnet
i got:
dotnet_install: Error: Download failed
Are there any missing?
Please use last valid URL:
curl -sSL https://raw.githubusercontent.com/dotnet/cli/rel/1.0.0-preview1/scripts/obtain/dotnet-install.sh | bash /dev/stdin --version 1.0.0-preview1-002702 --install-dir ~/dotnet
And it downloads and installs successfully on latest Raspbian on Raspberry Pi 2 (I think there should be no problem with Raspberry Pi 3).
However, after successful install, there is a error:
bash: dotnet: cannot execute binary file: Exec format error
I believe this is because of ARM architecture, because currently only amd64 (x64) is supported.

I installed Solaris 11.4 x86 in VirtualBox. I need to install the GCC compiler so that I can run c code in Solaris. But each time I try to install the package this error occurs:
Errors were encountered while attempting to retrieve package or file data for the
requested operation. Details follow:

I have used the following commands:
sudo pkg install developer/gcc/gcc-c-7
also tried -nv option
sudo pkg install -nv gcc
sudo pkg install -nv gcc-7
sudo pkg install -nv developer/gcc-7
see the output of the following command:

I am trying to solve this problem for 2 days. I have read documentation from
https://docs.oracle.com/cd/E37838_01/html/E60979/publisher-config.html
I also tried to install developerstudio 12.6 but it didn't work.
overall picture of error and command:
I have googled for errors tried to find information about errors and searched for how to install GCC on Oracle Solaris 11. I couldn't find any solution to this problem.
Try "wget http://pkg.oracle.com/solaris/release/p5i/0/developer%2Fgcc.p5i" or your preferred gcc package and manually install it with pkg install. You can try:
pkg install -v
after downloading.
According to the venv documentation in Python3:
Changed in version 3.5: The use of venv is now recommended for creating virtual environments.
With Python3.6 installed in my Ubuntu 16, I tried to create a Python project with command python3 -m venv project, but got the following error:
Error: Command '['/home/me/git/project/bin/python3', '-Im', 'ensurepip', '--upgrade', '--default-pip']' returned non-zero exit status 1.
Question: Why could this have happened? and how to resolve?
sudo apt-get install -y python3-pip is worth a try, based on https://www.digitalocean.com/community/tutorials/how-to-install-python-3-and-set-up-a-programming-environment-on-an-ubuntu-16-04-server
If that fails, what does python3 --version print?
Here is a list of the steps that I did in order to attempt to install Octave 4.2.1 in Centos 7 (repo version is 3.8.2 which is really old now)
1) yum update
2) yum-builddep -y octave
3) yum -y install qt-devel mercurial gcc-c++ lapack-devel libtool
4) yum -y install epstool transfig pstoedit qscintilla-devel
(NOTE: First problem was right here as there is NO pstoedit in Centos 7, as far as I know)
5) sudo yum install bzip2-devel atlas-devel libsndfile-devel portaudio-devel GraphicsMagick-c++-devel
6) ln -s /usr/lib64/atlas/libtatlas.so /usr/lib64/libatlas.so (One of the tutorials recommended doing this to fix a place where a library was being searched for or something like that. It seemed harmless enough)
7) wget ftp://ftp.gnu.org/gnu/octave/octave-4.2.1.tar.gz
8) tar-xvf octave-4.2.1.tar.lz
9) cd octave-4.2.1
10) export JAVA_HOME=/usr/lib/jvm/java-1.8.0-openjdk
11) ./configure --prefix=/usr/local/octave/versions/4.2.1
12) make -j4
It failed with this error:
In file included from libgui/src/settings-dialog.cc:31:0:
libgui/src/ui-settings-dialog.h:13:29: fatal error: QtWidgets/QAction: No such file or directory
#include <QtWidgets/QAction>
Has anyone come up with this problem and has some workaround or solution? Thanks
QtWidgets/QAction is specific to Qt5, and it seems that when you executed yum-builddep -y octave it got dependencies for Qt4. Configure octave with the option --with-qt=4. Another option is to install qt5 libraries and its devel files, configure --with-qt=5, and make.
Or you can just use Flatpack to install the latest version of Octave without any hassle:
flatpak install flathub org.octave.Octave
flatpak run org.octave.Octave
CentOS 7 already comes with built-in Flatpack app, but your distro doesn't have one you can install it:
sudo yum install flatpak
flatpak remote-add --if-not-exists flathub https://flathub.org/repo/flathub.flatpakrepo

I need help on installing saltstack on RHEL 7.
RHEL 7 server is from AWS Amazon.
$ cat /etc/redhat-release
Red Hat Enterprise Linux Server release 7.0 (Maipo)
I'm getting an error during installation:
$ wget -O - http://bootstrap.saltstack.org | sudo sh
2014-08-04 09:41:45 (932 KB/s) - written to stdout [177548/177548]

ERROR: Stable version is not available on RHEL 7 Beta/RC. Please set installation type to git.
ERROR: Failed to run install_red_hat_enterprise_linux_7_stable_deps()!!!
Is this version of RHEL 7 not supported for saltstack?
Run the following commands to install from the latest develop branch:
curl -o install_salt.sh -L https://bootstrap.saltstack.com
sudo sh install_salt.sh -M git develop
Remove the -M from the command above if you don't want to install a salt-master and only want to install salt-minion.
I have a similar problem, I tried to install it from epel 7 beta, but there's another problem, see https://bugzilla.redhat.com/show_bug.cgi?id=1127348. Finally I was able to install it by combining pip and yum. I don't have the exact sequence of commands, but sth. like this should work:
yum install --skip-broken salt python-pip
pip install jinja2
I have tried installing SaltStack on CentOS 7 , which should be similar to Redhat 7, and you could try it, hope it works for you:
**[updated]** http://dl.fedoraproject.org/pub/epel/7/x86_64/e/epel-release-7-2.noarch.rpm
and then you could
yum install -y salt-master
or
yum install -y install salt-minion
to install it.
You need to enable the rhel-7-server-optional-rpms repo in subscription-manager.
I want to run capybara-webkit in cloudbees, but I met this error in bundle
SocketCommand.h:4:19: fatal error: QObject: No such file or directory
compilation terminated.
I want to install Qt.
$ sudo apt-get install libqt4-dev
sudo: no tty present and no askpass program specified
$ apt-get install libqt4-dev
apt-get: command not found
How to install Qt? jenkins-plugin?
QT libraries are already installed on DEV#Cloud slaves,
to install capybara gem, you need to set
QMAKE=/usr/bin/qmake-qt4
then run cloudbees ruby add-on script
curl -s -o use-ruby https://repository-cloudbees.forge.cloudbees.com/distributions/ci-addons/ruby/use-ruby
RUBY_VERSION=1.9.3-p327
source ./use-ruby
and setup your build script to install dependencies
gem install --conservative bundler
bundle install
(or equivalent)
