I have some troubles installing Unity Hub on my Ubuntu 22.04.
I've followed the instruction from official Unity site, but the hub seem not working well.
Only black screen is shown and nothing else.
I am very lost with it! :(
The following codes has been runned:
sudo sh -c 'echo "deb https://hub.unity3d.com/linux/repos/deb stable main" > /etc/apt/sources.list.d/unityhub.list'
wget -qO - https://hub.unity3d.com/linux/keys/public | sudo apt-key add -
sudo apt update
sudo apt-get install unityhub
Thank you for your reply!
To resolve this issue you can install libssl1.1
I was also facing the same issue so I made an script that make it easy to install Unity hub on Ubuntu latest versions
#!/bin/bash
#Lib issue Ubuntu
wget http://security.ubuntu.com/ubuntu/pool/main/o/openssl/libssl1.1_1.1.1-1ubuntu2.1~18.04.20_amd64.deb
chmod +x libssl1.1_1.1.1-1ubuntu2.1~18.04.20_amd64.deb
sudo dpkg -i libssl1.1_1.1.1-1ubuntu2.1~18.04.20_amd64.deb
echo "deb http://security.ubuntu.com/ubuntu impish-security main" | sudo tee /etc/apt/sources.list.d/impish-security.list
sudo apt-get update
sudo apt-get install libssl1.1
#unityhub
sudo sh -c 'echo "deb https://hub.unity3d.com/linux/repos/deb stable main" > /etc/apt/sources.list.d/unityhub.list'
wget -qO - https://hub.unity3d.com/linux/keys/public | sudo apt-key add -
sudo apt update
sudo apt-get install unityhub
HOW TO USE BASH
Make a file with install.sh on Desktop.
Paste this code on install.sh file.
Open Terminal in "Desktop" location.
type chmod +x install.sh then press Enter.
type ./install.sh and press Enter.
After all the installing, Restart PC and then run UnityHub.
Unity Editor fails to launch and complains about "no usable version of libssl was found"
Ubuntu 22.04 now ships with libssl3 by default and does not include libssl1.1. Unity currently uses .NET5 which requires libssl1.1. To
work around this issue you can install libssl1.1 from an older Ubuntu
release
https://packages.ubuntu.com/bionic/amd64/libssl1.1/download
In a terminal:
echo "deb http://security.ubuntu.com/ubuntu impish-security main" | sudo tee /etc/apt/sources.list.d/impish-security.list
sudo apt-get update
sudo apt-get install libssl1.1
I have centos Machine as a docker host and i was trying to create a container with UBUNTU
my docker compose file in docker host is as following
FROM ubuntu:latest
RUN apt-get install -y git && \
apt-get clean
When i was trying to build the image i am getting the following error
This is the section for building the image
[root#testcent image_creation]# docker build -t ubuntu_git/venkat_ubu_git .

$ Can any one please help me
Normally docker base images won't support directly installing packages without update command. check and try out with the below if it works for you.
RUN apt-get update && apt-get install -y git && apt-get clean
I've cloned a copy of FreeCAD from github and I'm trying to create a docker file so that I can develop it locally on my machine.
The objectives being that:
I have a local copy of the code from git on my machine
I can make modifications to the code
I can build debug and release image (do I need to create two separate images?)
Have access to the code on my machine, so that I can use git for source control
This is the content of my Dockerfile:
# Get base image
FROM phusion/baseimage
# Use baseimage-docker's init system.
CMD ["/sbin/my_init"]
# Get the build pre-requisites
RUN apt-get update
RUN apt-get install -y build-essential cmake python python-matplotlib libtool
RUN apt-get install -y libcoin80-dev libsoqt4-dev

# Get git
RUN apt-get install -y git
RUN git clone https://github.com/FreeCAD/FreeCAD.git freecad
RUN cd freecad
RUN mkdir freecad-debug
RUN cd freecad-debug
# command below is just a diagnostic to let me know wth I am (output is: /)
# RUN pwd
RUN cmake ../ -DFREECAD_USE_EXTERNAL_PIVY=1 -DCMAKE_BUILD_TYPE=Debug .
#cmake -DFREECAD_USE_EXTERNAL_PIVY=1 -DCMAKE_BUILD_TYPE=Release .
RUN make
I attempt to build the image using the following command:
docker build -tag freeCAD-my-fork .
Everything works until I get to the first cmake invocation. I then get the following error:
CMake Error: The source directory "/" does not appear to contain CMakeLists.txt.
Specify --help for usage, or press the help button on the CMake GUI.
The command '/bin/sh -c cmake ../ -DFREECAD_USE_EXTERNAL_PIVY=1 -DCMAKE_BUILD_TYPE=Debug .' returned a non-zero code: 1
I placed a RUN pwd in my Dockerfile, so I could find where the cmake command was being run from, and I was surprised to find that it was been run from the root directory.
I thought the issue was being caused by my use of relative and that it would be fixed by absolute paths - however specifying /path/to/my/copy/freecad when cloning etc, the issue remains.
How can I write my Dockerfile so that it achieves the objectives outlined above (stated at the beginning of my question)?
Default WORKDIR in docker is "/".All docker commands will be executed in that directory.There are two option either you change WORKDIR(https://docs.docker.com/engine/reference/builder/#workdir) or execute everything in one layer(In one RUN command).I have taken second approach.
Cloning and Building source code both executed in One layer of docker.
RUN git clone https://github.com/FreeCAD/FreeCAD.git freecad \
&& cd freecad \
&& mkdir freecad-debug \
&& cd freecad-debug \
&& cmake ../ -DFREECAD_USE_EXTERNAL_PIVY=1 -DCMAKE_BUILD_TYPE=Debug . \
&& make
You should install all your dependencies using run as you do but the actual building and copying of source code files should not happen when you build your image but when you run a container.
This way you can reuse your image for as many builds as you like.
Write a script with the build commands and copy it over to your image. Then in the CMD part of the dockerfile run that script.
To share the git project with the container you can mount your local files with docker run -v hostpath:containerpath imagename. That way any files in hostpath will be visible to the container at containerpath and vice versa. Alternatively you could also git clone from the script which is invoked by CMD but then you have to expose the build somehow to your host (some mounted volume again).
What's the best way to upgrade Visual Studio Code on Linux Ubuntu?
For the time being I was periodically getting the newest version (.deb) from their official site: https://code.visualstudio.com/
sudo dpkg -i code_*.deb
Visual Studio Code enabled official Linux repositories on February 2017 (v1.10)
sudo add-apt-repository -y "deb https://packages.microsoft.com/repos/vscode stable main "
sudo apt update
sudo apt -y install code
You can upgrade / dist-upgrade as usual
sudo apt -y upgrade
sudo apt -y dist-upgrade
[1]: download the latest vscode (.deb) package to your computer on this
link :
https://go.microsoft.com/fwlink/?LinkID=760868
, or this there :
https://code.visualstudio.com/docs/
[2]: then open a terminal in the folder where you downloaded the .deb file and write:
sudo dpkg -i <the downloaded file>.deb
[3]: finally if you have apt-get do (if not install apt-get first):
sudo apt-get install -f
If you have installed it via the repository, exit VS Code then just do:
sudo apt update
sudo apt install code
This is the same command to install or upgrade to the latest version. You can see the version with:
code --version
Now the easiest and recommended way is to use snap:
sudo snap install --classic code
And updates are supposed to be automatic.
This works fine in ubuntu.
sudo apt-get update
sudo apt-get install code
When you install VSCode with the file .deb on Ubuntu 20.08, first, remove it:
sudo apt-get remove code
Add the repository in this link https://code.visualstudio.com/docs/setup/linux
wget -qO- https://packages.microsoft.com/keys/microsoft.asc | gpg --dearmor > packages.microsoft.gpg
sudo install -o root -g root -m 644 packages.microsoft.gpg /etc/apt/trusted.gpg.d/
sudo sh -c 'echo "deb [arch=amd64 signed-by=/etc/apt/trusted.gpg.d/packages.microsoft.gpg] https://packages.microsoft.com/repos/vscode stable main" > /etc/apt/sources.list.d/vscode.list'
Udate the package cache and reinstall
sudo apt-get install apt-transport-https
sudo apt-get update
sudo apt-get install code
In the next time when you want to upgrade, just do:
sudo apt-get update
sudo apt-get upgrade code
Because your repository is missing information to upgrade VSCode, the above solution will fix it.
This is what I did to avoid the annoying message:
Remove vscode, if you already installed it.
sudo apt-get remove code
Add repositories, update and install:
sudo add-apt-repository -y "deb [arch=amd64] https://packages.microsoft.com/repos/vscode stable main "
sudo apt update
sudo apt -y install code
If you have already installed VS code, go to the terminal and type two different commands:
sudo apt update
sudo apt-get upgrade code
The following commands work for me (for Linux) :
wget 'https://code.visualstudio.com/sha/download?build=stable&os=linux-deb-x64' -O /tmp/code_latest_amd64.deb
sudo dpkg -i /tmp/code_latest_amd64.deb
Place those two commands into an executable Bash script called auto-update-VSCode, and you can simply run that from your shell any time Visual Studio Code says it's out of date.
I'm running Ubuntu 20.04 and this worked perfectly for me:
$ wget https://vscode-update.azurewebsites.net/latest/linux-deb-x64/stable -O /tmp/code_latest_amd64.deb
$ sudo dpkg -i /tmp/code_latest_amd64.deb
Best way to update Vscode in Ubuntu:
sudo apt-get update
sudo apt-get install code
sudo apt-get update
sudo apt-get install code
I am trying to run the commands:
apt-get -y install npm
apt-get -y install nodejs
using install4j.
OS: Ubunto.
I tried to add sh file with those commands (but it not run).
Tried to run:
!/bin/bash
apt-get -y install npm
apt-get -y install nodejs
exit 0
But with Install4j it now run.
Remember to make the shell script file executable in the installer before trying to run it.
