I have installed ROS using
sudo apt-get install ros-desktop-full
all tutorial on the net says configure enviroment setup using command
source /opt/ros/<dist>/setup.bash
I don't find any folder with the name ros in my /opt/
I can only see only following folders after executing the command
$ ls /opt/
atom google SQLiteStudio zoom
You used the wrong apt command. You should use sudo apt install ros-<distro>-desktop-full. Assuming you're on Ubuntu20.04 and wanting to run ROS Noetic the command is sudo apt install ros-noetic-desktop-full.

I'm trying to setup Pipenv on Ubuntu 22.04 LTS and I used:
sudo apt install pipenv
but I get an error:
FileNotFoundError: [Errno 2] No such file or directory: '/home/foo/.local/share/virtualenvs/hello-JDpq8NmY/bin/python'
I tried to update pip with:
curl -sS https://bootstrap.pypa.io/get-pip.py | python3.10
Still no use.
I tried the solution suggested here and nothing changed.
The environment is there but the bin folder is missing.
I had the same problem. Remove pipenv from apt package manager and install pipenv with
pip install pipenv
After this you must set your PATH Variable to the pip dictionary.
A possible problem is related to pipenv not finding the python executable.
If this is your case is it possible to specify the path
pipenv install --python=/usr/bin/python3.10
Replace the path with desired python version

I'm running a Bitnami/pytorch container and would like to install packages using apt. However I cannot do it as sudo is not installed. For example:
$ sudo apt install nano
bash: sudo: command not found
So what is the preferred way of getting apt install to work?
I'm on a RHEL7.6 attempting to run
docker-credential-secretservice
I've installed it by
wget https://github.com/docker/docker-credential-helpers/releases/download/v0.6.0/docker-credential-secretservice-v0.6.0-amd64.tar.gz && tar -xf docker-credential-secretservice-v0.6.0-amd64.tar.gz && chmod +x docker-credential-secretservice && mv docker-credential-secretservice /usr/local/bin/
when i try to run it by going
docker-credential-secretservice
error:
docker-credential-secretservice: error while loading shared libraries: libsecret-1.so.0: cannot open shared object file: No such file or directory
I thought the libsecret-1.so.0 wasn't installed so i installed it
sudo yum install libsecret-1.so.0
but still gives the same error.
question
how do i install docker-credential-secretservice?
To fix this issue, you need to install libsecret.
sudo yum install libsecret -y
This will install the lastest version of libsecret and you will be able to use it as a credential helper for Docker.
Once installed, you can test it with
docker-credential-secretservice version
On Ubuntu, using apt, I had to specify:
sudo apt install libsecret-1-0
Then docker-credential-secretservice ran with no issue.
I am trying to build a docker container based on amazonlinux which is sort of centos.
One of the packages I need is supervisor and it is not available on the official repos so I have to do it with easy_install or pip.
The problem is that, although I tried installing python-setuptools and python-pip, then when I try to do:
RUN easy_install supervisor
or
RUN pip install supervisor
It says the command doesn't exists
/bin/sh: easy_install: command not found
The command '/bin/sh -c easy_install supervisor' returned a non-zero code: 127
I tried with full path, but same result, and I see other dockerfiles people doing it like that on centos images.
After a while, I found the reason.
By default, yum was installing python26 and the easy_install script runs with python27, so I had to be calling easy_install-2.6 or install the python27 package
Not familiar with AWS's specific image, but for a general centos image, you'll need to install pip or easy_install with a yum command first, which requires the epel repository:
RUN yum -y install epel-release \
&& yum -y install python-pip python-setuptools \
&& yum clean all
Python documented the process in detail on their page here: https://packaging.python.org/install_requirements_linux/

While installing erlang on cent os I got the following error
Error: Package: erlang-crypto-R16B03-0.2.el6.x86_64 (erlang-solutions)
Requires: libcrypto.so.10(libcrypto.so.10)(64bit)
Error: Package: erlang-crypto-R16B03-0.2.el6.x86_64 (erlang-solutions)
Requires: libcrypto.so.10(OPENSSL_1.0.1)(64bit)
You could try using --skip-broken to work around the problem
You could try running: rpm -Va --nofiles --nodigest
I searched around on google and found that the probelm can be solved by installing openssl-devl. So I did that and tried installing erlang again but got the same error.
How can I install the latest version of erlang on cent os 6.4?
How you are installing it? According to Riak's documentation, you use:
sudo yum install gcc glibc-devel make ncurses-devel openssl-devel autoconf
And then, you build Erlang:
wget http://erlang.org/download/otp_src_R15B01.tar.gz
tar zxvf otp_src_R15B01.tar.gz
cd otp_src_R15B01
./configure && make && sudo make install
Installing Erlang on GNU/Linux
You can install erlang using erlang-solution repo
Install repo
wget http://packages.erlang-solutions.com/erlang-solutions-1.0-1.noarch.rpm
rpm -Uvh erlang-solutions-1.0-1.noarch.rpm
Install erlang
sudo yum install erlang
This worked for me on centos7...
sudo yum install epel-release
sudo yum update
wget http://packages.erlang-solutions.com/erlang-solutions-1.0-1.noarch.rpm
sudo rpm -Uvh erlang-solutions-1.0-1.noarch.rpm
sudo yum install erlang
Using EPEL from Fedora is a surefire way on Centos 6. I currently have erlang-crypto-R14B-04.3.el6.x86_64 installed. If you have different repos enabled it could be a conflict or that there is an issue with the package from the other repo (I would recommend disabling whatever repo that provides it or at least ignoring erlang from that repo).
Here is a simple way to install EPEL on Centos
rpm -ivh https://dl.fedoraproject.org/pub/epel/epel-release-latest-6.noarch.rpm
yum -y install erlang-*
your error is
"Error: Package: erlang-crypto-R16B03-0.2.el6.x86_64"
so you can download&install R16B03
wget http://erlang.org/download/otp_src_R16B03.tar.gz
tar -zxvf src_R16B03.tar.gz
cd src_R16B03.tar.gz
yum localinstall erlang
To install erlang in centos offline.Follow below steps,
We need to have one internet connected machine to download rpm's.
yum install yum-plugin-downloadonly -y
yum install --downloadonly --downloaddir=/home/user/ erlang
All of erlang dependencies packages downloaded as rpm on /home/user/ directory
Now copy all rpm's to offline machine in any directory ( eg., /home/user/ )
Type following command to install erlang with its dependencies too.,
cd /home/user/
rpm -Uvh *.rpm
It's Done!
check using command,
erl
(press Ctrl+c twice to get exit from erl command )
