I am trying to run carla simulator in a google colab with python jupyter notebook.
I followed the guide and I executed the following commands
!pip install pygame
!pip install numpy
!sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys 304F9BC29914A77D
!sudo add-apt-repository "deb [arch=amd64 trusted=yes] http://dist.carla.org/carla-0.9.8/ all main"
!sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys DB53A429E64554FC &&
!sudo add-apt-repository "deb [arch=amd64 trusted=yes] http://dist.carla.org/carla-0.9.7/ all main"
!sudo apt-get update
!sudo apt-get install carla
however when I tried to run it I got an error
Package carla is not available, but is referred to by another package.
This may mean that the package is missing, has been obsoleted, or is
only available from another source
E: Package 'carla' has no installation candidate
how can I install the carla simulator on google colab?
You can try to use this repo: https://github.com/MichaelBosello/carla-colab
There is google colab notebook with pre-installed Carla.

I am unable to install the R package ggplot2 because it depends on the package digest, which requires R (>= 3.3.0) and I only have 3.2.3. I tried upgrading R as described here, but I get an unusual message after the first line and an error after the third. The results of the first 3 lines are below exactly as the appear on the command terminal, edited for privacy and empty lines before commands added for clarity.

All commands after the third give the same errors, with commands 4 and 6 giving the errors twice for some reason.
I will be frank and admit that this whole think is very beyond me and I am just copying and pasting the code that supplied without understanding most of it. Any help will be greatly appreciated.
EDIT: Answer available here.
You are almost there, but it seems like your sources.list may be malformed.
First delete all entries related to R by using nano /etc/apt/sources.list (or your favorite editor).
Then as you did add the key
$ sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys E298A3A825C0D65DFD57CBB651716619E084DAB9
Then add the correct repository
sudo add-apt-repository 'deb https://cloud.r-project.org/bin/linux/ubuntu bionic-cran35/'
Quick update
sudo apt update
Install r-base by
sudo apt-get install r-base
And confirm everything is working with
R --version
I have tried to upgrade R from 3.4.4 to 4.0 in Ubuntu 16.04.7 LTS (Xenial Xerus). I have followed and run the following scripts.
$ sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys E298A3A825C0D65DFD57CBB651716619E084DAB9
$ sudo add-apt-repository 'deb https://cloud.r-project.org/bin/linux/ubuntu xenial-cran40/'
$ sudo apt-get update
$ sudo apt install r-base
Output:
"Reading package lists... Done
Building dependency tree
Reading state information... Done
r-base is already the newest version (3.4.4-1xenial0)".
The terminal always showed that "r-base is already the newest version" and refused to upgrade. I tried to upgrade R 3.6 as well and got a similar issue. Any thoughts? Thank you so much for your help.
If I run this
sudo apt-get install r-base
R 3.4 is installed from the ubuntu repo. So I added the CRAN repositories by doing
sudo add-apt-repository 'deb https://cloud.r-project.org/bin/linux/ubuntu eoan-cran35/'
sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys E298A3A825C0D65DFD57CBB651716619E084DAB9
sudo apt update
sudo apt install r-base
but then I get
The following packages have unmet dependencies:
r-base: Depends: r-base-core (> = 3.6.3-1eoan) but 3.4.4-1ubuntu1 is going to be installed
Depends: r-recommended (= 3.6.3-1eoan) but 3.4.4-1ubuntu1 is going to be installed
E: Problems cannot be corrected, you have retained broken packages.
I swear I tried every line of code from every forum I found but nothing solved this issue. I tried:
sudo apt update && sudo apt-get autoclean && sudo apt-get clean && sudo apt-get autoremove
sudo apt install --fix-broken
sudo apt-get install -f
sudo apt dist-upgrade -y
sudo apt full-upgrade
I also tried disabling ubuntu repos and use only the CRAN repositories, but it doesnt work.
I tried installing r-base 3.4 and upgrading from that but nothing.
I really don't know what else to do, any ideas?
It depend of the version of Linux Mint you are running, but based on your code, you are trying to install r-base for Ubuntu 19.10 eoan (which is not a LTS).
The last version of Linux Mint 19.3 is based on Ubuntu 18.04 Bionic, so you should edit your /etc/apt/sources.list file and add
deb https://cloud.r-project.org/bin/linux/ubuntu bionic-cran35/
Then:
sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys E298A3A825C0D65DFD57CBB651716619E084DAB9
sudo apt-get update
sudo apt-get upgrade
sudo apt-get install r-base-dev
All informations from cran are here: https://cran.r-project.org/
For Linux Mint, check this page (https://www.linuxmint.com/rel_tricia_xfce_whatsnew.php):
> Linux Mint 19.3 features Xfce 4.14, a Linux kernel 5.0 and an Ubuntu 18.04 package base.
I am trying to update to R version 3.5.3, by using the R manual. However, when I type this line:
deb https://cloud.r-project.org/bin/linux/ubuntu cosmic-cran35/
I get a return of command not found.
I tried to add it to my source list as previously suggested, but this does not seem to work. I am trying to do this on a linux system
Edit: Thanks #Ralf for correction (see comments)
Append the 'deb' line to your sources.list by opening a terminal and typing:
echo "deb https://cloud.r-project.org/bin/linux/ubuntu cosmic-cran35/" | sudo tee -a /etc/apt/sources.list
Install the R-CRAN GPG key to verify what you're installing:
sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys E298A3A825C0D65DFD57CBB651716619E084DAB9
Update your package list and install with:
sudo apt update
sudo apt install r-base r-base-dev
I am trying to install the latest version of R (3.4.0) due to some incompatibility issues with dowloading of a package called "Slam". I have downloaded the tar.gz file of 3.4.0 but there are some issues with the make file for installation.
I have uninstalled the r-base of 3.2.3. Now when I'm installing R again, I get the same version instead of the upgrade version. I even ran the sudo apt-get update command but in vain.
you need to install from the CRAN repos not the ubuntu ones. add the key, then the repository, update and the apt-get
sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys E298A3A825C0D65DFD57CBB651716619E084DAB9
sudo add-apt-repository 'deb [arch=amd64,i386] https://cran.rstudio.com/bin/linux/ubuntu xenial/'
sudo apt-get update
sudo apt-get install r-base
