I have been working in Inkscape for the past week. Last night, Inkscape suddenly stopped functioning. That is:

  • It takes a very long time to load. When started, it looks frozen, Ubuntu asks me if I want to force it to quit, but if I wait 1-2 minutes, it recovers
  • If I try to perform any operation to edit an image in Inkscape, at each click/action, it freezes for a few minutes.

What I tried:

  • uninstall and then install again Inkscape - did not help

My system: Ubuntu 18.04.4 LTS

My system: Ubuntu 18.04.4 

Rscript --version
R scripting front-end version 3.4.4 (2018-03-15)

My problem: Unsuccessful in upgrading R.

Steps:

sudo apt-get remove r-base r-base-dev
sudo add-apt-repository 'deb https://cloud.r-project.org/bin/linux/ubuntu bionic-cran35/'
sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys E298A3A825C0D65DFD57CBB651716619E084DAB9 (as instructed here: https://cran.r-project.org/bin/linux/ubuntu/)
sudo apt update
sudo apt install r-base r-base-core r-recommended

Output:

The following packages have unmet dependencies.
 r-base-core : Depends: libreadline6 (>= 6.0) but it is not installable

When trying to install libreadline6 I get:

sudo apt install libreadline6
Reading package lists... Done
Building dependency tree       
Reading state information... Done
Package libreadline6 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 'libreadline6' has no installation candidate
dependencies r 18.04

I have a Microsoft Surface tablet, Windows 10 and I run Windows Subsystem for Linux with Ubuntu.

I would like to know if WSL can access the integrated camera of my tablet.

All other articles/questions/other online resources I have come across only talk about WSL not accessing a USB camera, but none mention explicitly an integrated camera.

Requested info: WSL version: I have Microsoft Surface Pro 4 with Windows 10. OS build is 18362 and I've tried wsl -l which fails. So, my understanding from these two is that I have WSL (v1)

xx@Surface:~$ sudo lspci && lsusb
[sudo] password for :
pcilib: Cannot open /proc/bus/pci
lspci: Cannot find any working access method.
