Package r-base-core is not configured yet in Ubuntu 18.04.2

Question

I used sudo dpkg --configure -a but it shows like below.

dpkg: dependency problems prevent configuration of r-cran-class:
 r-cran-class depends on r-base-core (>= 3.5.0-1); however:
  Package r-base-core is not configured yet.
 r-cran-class depends on r-api-3.5; however:
  Package r-api-3.5 is not installed.
  Package r-base-core which provides r-api-3.5 is not configured yet

How do I fix it?

Output of apt depends r-cran-class:

r-cran-class
  Depends: r-base-core
  Depends: r-cran-mass
  Depends: libc6 (>= 2.4)

Check if you are using third party repositories. If so disable them, since they are a common source of problems.
Furthermore run the following command in a Terminal: apt-get install -f
Transaction failed: The package system is broken
 The following packages have unmet dependencies:

r-cran-foreign: Depends: libc6 (>= 2.14) but 2.27-3ubuntu1 is installed
                Depends: r-base-core (>= 3.5.1-1bionic) but 3.4.4-1ubuntu1 is installed

r-cran-nnet: Depends: r-api-3.5 but it is a virtual package
r-cran-spatial: Depends: r-api-3.5 but it is a virtual package

I think i need to remove 3.4.4-1ubuntu1, 2.27-3ubuntu1 and install sudo dpkg -i r-base-core_3.5.1-1bionic_amd64.deb Am i right?

Let's fix the issues one by one.

Remove r-base-core:

Run
```
sudo apt autoremove r-base-core
```
W: Target CNF (non-free/cnf/Commands-all) is configured multiple times

The easiest way to solve this issue is following David's Script. But if you don't want to follow that script and since you have issue in single line, you can simply run,
```
sudo sed -i '4d' /etc/apt/sources.list.d/opera-stable.list
```
Remove PPAs of some other release.

Since you are using Bionic Beaver (18.04), Xenial Xerus's (16.04) PPA information won't help in anyway and might create dependency problems in future. I would suggest removing or commenting them. Run
```
grep "xenial" /etc/apt/sources.list /etc/apt/sources.list.d/*
```
It would generate output which would help you to determine those files. Edit them using sudo privileges and some editor such as nano and put a # in front of them. To open them run
```
sudo nano filename
```
Save them using Ctrl+X followed by Y. If those files contain a single line only which is of xenial, you may delete that.
dpkg: warning: files list file for package 'x' missing; assuming package has no files currently installed

Copy whole error message in some text file, say 1.txt and run
```
for package in $(cat 1.txt | grep "warning: files list file" | sed "s/.*\`//; s/'.*//"); do echo "$package"; done >> 2.txt
```
^{Credits: zaTricky's answer on dpkg: warning: files list file for package 'x' missing}

Copy all packages name and run
```
sudo apt install --reinstall packages_name
```
You can reinstall multiple packages by pasting multiple packages' name in one command.

Configure (if some left):

Run:

sudo dpkg --configure -a
sudo apt update
sudo apt upgrade

Install r-base:

Run
```
sudo apt install r-base
```

A mix between bionic xenial artful and ppa packages.

Remove under /etc/apt/sources.list.d/ any file with xenial or artful in name.

Control in /etc/apt/sources.list That every row leads to a bionic source.

sudo add-apt-repository -r ppa:marutter/rrutter3.5

removes that ppa.

You have another on cloud.r-project.org/bin/linux/ubuntu bionic-cran35 for that packages. I'am not sure if this works. sudo apt update && sudo apt-get clean

sudo apt -f install --reinstall r-cran-class=7.3-15-1bionic0

If is not working wget -c https://cloud.r-project.org/bin/linux/ubuntu/bionic-cran35/r-cran-class_7.3-15-1bionic0_amd64.deb for 64-bit or wget -c https://cloud.r-project.org/bin/linux/ubuntu/bionic-cran35/r-cran-class_7.3-15-1bionic0_i386.deb for 32-bit system. Install it directly with sudo dpkg -i /path/to/your deb sudo dpkg --configure -a && sudo apt -f install

Not working after using your solution. – Mamun Or Rashid Jul 14 '19 at 10:38 — Mamun Or Rashid, Jul 14 '19 at 10:38

Package r-base-core is not configured yet in Ubuntu 18.04.2

Remove r-base-core:

`W: Target CNF (non-free/cnf/Commands-all) is configured multiple times`

Remove PPAs of some other release.

`dpkg: warning: files list file for package 'x' missing; assuming package has no files currently installed`

Configure (if some left):

Install r-base:
