I have just, in my groggy morning state, reversed & confused the arguments to ln, replacing /usr/share/zoneinfo/America/Toronto with a link to the non-existant /etc/localtime, when I really wanted to link /etc/localtime to Toronto. Now I have no timezone file for where I live. Does anybody have a copy or know where I could get one? It's just instructions on how to translate unix time into toronto time, but I cat'd a few of the other files, and they don't seem like something I'm up to the task of writing by hand.
I know. At least I've never rm -r'd my /
edit:
Before anybody asks, I just tried sudo dpkg-reconfigure tzdata, gleefully entered "America" then "Toronto", only to crash and read, cp: cannot stat '/usr/share/zoneinfo/America/Toronto': no such file or directory. ARGH.
apt-get install --reinstall tzdata
Depending on which GNU/Linux distro you're using, you may be able to just re-download the whole of the tzdata package using its package manager. I know ArchLinux has a package for the time zone data and so does Debian.
However, you can also manually download the whole package and extract the time zone file that you want.

I'm trying to use Github Actions to build a Xaringan presentation.
But it seems that it can't find xaringan.
Other dependencies are installed correctly, even xaringanthemer (see logs link below) !
I tried to see if there is some missing dependencies but even after fiwing that, xaringan is still missing.
Infos
Env: Github Actions
OS: Ubuntu 20.04
R: 4.1.0
REPO_NAME: "https://packagemanager.rstudio.com/all/__linux__/focal/latest"
Config file: https://github.com/gflowiz/article_foss4g2021/blob/presentation_FOSS4G2021/.github/workflows/render-xaringan.yaml
How to reproduce:
clone repo and trigger build
Ideas of possible fix
Signal to Rstudio and wait for a fix ?
That's strange because Xaringan seems to be present on the repo: https://packagemanager.rstudio.com/client/#/repos/1/packages/xaringan
Change repo
Can I change to CRAN instead of packagemanager.rstudio.com ? What's the URL to use ?
Other packages seems to be downloaded from https://cloud.r-project.org/src/contrib
Your issue came from the spelling: you are using xarigan instead of xaringan in your workflow file at line 48
Therefore, when you try installing the package, you got:
In your last workflow run.
Here is a workflow run using the correct syntax
, but it seems to return another error related to a .gitignore file missing after generating the FOSS4G2021_presentation.html output file:
I'll let you handle it from here (as I've never used these tools before) :D

I need to use sbt for run spark in my fedora box, but what surprised me most is
sbt cannot use in my Fedora, I've tried two fedora machines, both failed.
I guess a lot of people meet this problem before, any ideas?
Thanks.
Jovi
UPDATE
For RPM based distributions ( http://www.scala-sbt.org/0.13/tutorial/Installing-sbt-on-Linux.html ) following instructions work:
curl https://bintray.com/sbt/rpm/rpm | sudo tee /etc/yum.repos.d/bintray-sbt-rpm.repo
sudo yum install sbt
OLD INSTRUCTIONS
Setting up SBT on fedora is pretty straightforward.
Older version sbt-0.12.2:
$ sudo yum localinstall http://scalasbt.artifactoryonline.com/scalasbt/sbt-native-packages/org/scala-sbt/sbt//0.12.2/sbt.rpm
Latest version sbt-0.13.1:
$ sudo yum localinstall http://repo.scala-sbt.org/scalasbt/sbt-native-packages/org/scala-sbt/sbt/0.13.1/sbt.rpm

Is there any way to know when a crontab was installed on ubuntu server?
Thanks
You can list user's cron tabs:
sudo ls -l /var/spool/cron/crontabs
To see when those files were last changed.
Also, you could read your logs (/var/log/syslog) and search for crontab keyword.
On a default installation of a cron job using crontab -e, the cron get logged in var/log/syslog file.
You can see when a cron job was was installed from that file by running:
grep "END EDIT" /var/log/syslog
The date and time is firt on the line.
Source: https://askubuntu.com/a/56811/147044
try crontab -e . Add 0 0/5 * * * /your/path/to/script/

I am wanting to use RHadoop packages(rmr, rhdfs, rhbase) on my ubuntu server. These only work with the older version of R 2.15.0 and not on the current 3.0.1 version. I have created a mirror which allowed me to install the 3.0.1 version.
sudo apt-get install r-base-dev
What do I need to change here to get the 2.15.0 version of R?
I have tried using the links but i think I might need to access a new mirror since the link to both downloads are different.
current mirror:
deb http://cran.cnr.berkeley.edu/bin/linux/ubuntu precise/
I assume its getting the most recent file and executing it:
http: //cran.cnr.berkeley.edu/bin/linux/ubuntu/precise/r-base-dev_3.0.1-5precise0_all.deb
The link I want it to follow and install
http: //cran.cnr.berkeley.edu/src/base/R-2/R-2.15.0.tar.gz
After berkeley.edu it is all different but in my mirror it would stay the same. I have tried changing my mirror but haven't had any luck.
If anyone has any suggestions or can lead me down the right path that would greatly help.

You will find previous binary builds for Ubuntu in the standard directory, just by hand:
https://cran.r-project.org/bin/linux/ubuntu/
You can always download them manually and then tell the package management system to put them 'on hold', ie to not upgrade. See eg man dpkg for the dpkg --set-selection and the hold state.
You find outdated versions of R at the CRAN page:
http://cran.r-project.org/sources.html
Following a couple of links:
http://cran.r-project.org/src/base/R-2/R-2.15.0.tar.gz
I suppose it is possible that that Debian/Ubuntu repository has the Make files to drive the compilation from source. If not, you can probably find one on the R-Debian mailing list.

Its my first time working with cygwin so bear with me please.
I need to install a processing library via cygwin in order for it to work.
I followed all the steps in this tutorial and in the last step (00:22 seconds mark) I need to "cp" LeapMotion to the directory where Processing stores it's librarys.
I store mine in "D:\Processing Sketches\libraries" and i don't know how to copy it there. I'm confused with the ~/home/ part.
I tried "$ cp -R LeapMotion /D:/Processing\ Sketches/libraries/" but that doesnt work :/
Under cygwin DOS drive letters are mapped to /cygdrive/<drive>, so you would do it like this:
$ cp -R LeapMotion /cygdrive/d/Processing\ Sketches/libraries/
