Couldn’t delete a failed R package installation

Couldn’t delete a failed R package installation

Comments 0 Comment

Today I faced a strange thing, while I tried to install an update to one of my R-packages. As usually, I installed the latest version from it like this

library("devtools")
install_github("fischuu/GenomicTools")

But the installation failed, and when I tried to reinstall it, I got this error message:

Installing package into ‘/homeappl/home/<user>/R/x86_64-redhat-linux-gnu-library/4.1’
(as ‘lib’ is unspecified)
ERROR: failed to lock directory ‘/homeappl/home/<user>/R/x86_64-redhat-linux-gnu-library/4.1’ for modifying
Try removing ‘/homeappl/home/<user>/R/x86_64-redhat-linux-gnu-library/4.1/00LOCK-GenomicTools’
Warning message:
In i.p(...) :
  installation of package ‘/tmp/Rtmp<...>Lv/file3c36<...>34/GenomicTools_0.2.11.tar.gz’ had non-zero exit status

So, I tried to go in said directory and delete the folder manually and there I received another error:

rm: cannot remove '00LOCK-GenomicTools/GenomicTools/libs/.nfs00000001002e2<...>d': Device or resource busy

I tried this and this, but nothing helped to delete that folder, it kept mocking my that the device is busy. Eventually, it helped just to rename the folder list this

mv 00LOCK-GenomicTools/ 00LOCK-GenomicTools-deleteThis/

It is now still hanging there in the folder, but I was able to reinstall the R-package and now I need to revisit the folder in a few days and check, if the device is still busy or if I can delete it then…

[D] Ich bin ja nun mal weit davon entfernt ein CDU-Wähler zu sein, aber ich kann nicht anders, als mich darüber zu wundern, was da gerade zwischen Laschet/CDU und Söder/CSU abläuft! Wie kann jemand ohne gravierende Gedächtnisprobleme ernsthaft Söder für kanzlertauglich halten?! Klar, die Abgeordneten stehen hinter ihm, da sie sich evtl bessere Chancen auf einen erneuten Sitz im Bundestag ausrechnen – aber trotzdem, da darf auch Mal hinterfragt werden, mit welchem Preis das kommt!

Falls Söder tatsächlich der Kanzlerkandidat wird hoffe ich inständig, dass viele Bürger kein so schlechtes Gedächtnis haben wie momentan viele CDU Mitglieder!

Man darf hoffen, dass andere Parteien da einen Nutzen draus ziehen können…

Starting today the restaurants are again open in Finland. Of course, Corona is not over yet, there are still many people getting it and one still needs to be careful while being out, but still having a small breakfast out feels quite nice (although the lockdown was not even that long compared to other countries).

However, let’s hope the vaccines will start to have an effect and that severe infections or even deaths will vanish soon and we can start to live normal lifes again.

In that sense, have a nice start into the week!

As emergency food a bought some time ago a ‘British Style Snackbox’… Today was the day of emergency where I was too lazy to cook, opened it and got straight away good mooded! All different snacks a packed in separate plastics, in bag sizes two/three times the size that would be needed. What the f*ck?! What for do those bags need to be that big, Lidl?!

Brötchen

A very simple, but tasty way to get fresh Brötchen (rolls) in the morning. The dough is prepared in the evening and the dough raises during the night in the fridge. In the morning the rolls only need to be formed and put into the oven.

Servings
10-12 Brötchen


Ingredients

Instructions
  1. Mix all ingredients into a large bowl, cover it with a towel and place it into the fridge for approx 12 hours (meaning, if you want to have fresh Brötchen in the morning, do the dough in the evening...).

  2. Form small, round shaped Brötchen (add some flour to your hands to avoid the dough to stuck on your hands...), place them on a baking tray and back them for 25 minutes at 230 degrees.

    Ideally, if you have a steam oven, add some (250ml) water to it, otherwise place a bowl with water into the oven.
