I just installed shiny server and I get an error when I load the shiny web page:
An error has occurred. The application failed to start shows on the right side of the screen.
Then I checked the log and shows:
su: ignore --preserve-environment, it's mutually exclusive to --login.
Fatal error: unable to open the base package
When I type su - shiny and I try to run R I also get the Fatal error: unable to open the base package, so I guess there is a problem with R.
I can load R when I'm root or R user and apparently R works fine.
Any idea? Could it be a PATH problem? If yes, I couldn't find it out.
Thanks in advance.

I installed elementary OS. I was trying to download apps with flatpak. I downloaded flatpakref files into "~/Downloads/flatpak/" directory. Then i wrote sudo flatpak install com.discordapp.Discord.flatpakref.
I got an error like this
error: No entry for app/com.discordapp.Discord/x86_64/stable in remote 'freedesktop' summary flatpak cache
Then i thought that the discord package is broken. I tried with Atom text editor.
Then i got this error
error: No entry for app/io.atom.Atom/x86_64/stable in remote 'freedesktop' summary flatpak cache.
I searched about the error but i couldn't find anything. What is this error and how can i fix this?

I had the same problem! this solved!
" Looks like the dependency manager has a problem with the non-ASCII characters in your user name.
Try adding -Dsbt.global.base=C:/some/other/path to the command line of the SBT process. This will relocate files from the default location of %USERHOME%/.sbt. "
I am about to begin a project with Shiny (by RStudio). When I try to install the shiny package using the console install.packages("shiny"), I get the following error message:
trying URL 'http://cran.rstudio.com/bin/macosx/mavericks/contrib/3.1/shiny_0.10.1.tgz'
Warning in install.packages :
cannot open: HTTP status was '404 Not Found'
Error in download.file(url, destfile, method, mode = "wb", ...) :
cannot open URL'http://cran.rstudio.com/bin/macosx/mavericks/contrib/3.1/shiny_0.10.1.tgz'
Warning in install.packages :
download of package ‘shiny’ failed
I have tried to install it from the drop down menu in RStudio but have encountered the same problem. Any thoughts as to what is going on?
I am working on Mac, with the latest version of Mavericks (R version is 3.1.1).
Thanks,
Brian
Try a different CRAN mirror. The error indicates that the file was not found on the CRAN server
chooseCRANmirror()
shiny has just been updated 2014-10-01 so the changes may not have propagated down to all mirrors yet.
I'm trying to take screenshots of some webpages. I opted for selenium and firefox. I'm using xvfb and setting an environment variable for the display.
The script works fine without xvfb on OS X desktop. However on the server the script hangs after webdriver.Firefox() is issued as if the python script is no longer executing. No exception is ever raised and firefox is still active in my process list.
Setup:
sudo Xvfb :10 -ac
export DISPLAY=:10
test.py
from selenium import webdriver
print 'start'
firefox = webdriver.Firefox()
print 'Hello?'
firefox.quit()
print 'done!'
output:
start
cursor winks tauntingly
I Had the same problem with Chrome. Also tried the phantomJs flash fork, this was successful but did not capture flash content.
starting independently firefox gives
