apt-get purge libc6-dev-i386 want to remove important packages

Question

Why is this code not changing the size of the figure plotted?

   fig1, ax1 = plt.subplots(nrows=1, ncols=3)
   fig1.set_figheight = 30
   fig1.set_figwidth = 30
   x = np.array([1,2,3,4,5])
   for i in range(3):
       ax1[i].plot(x, x**i)

[This is what I am getting][]1

Is there a way to make them bigger?

Solution 1

After searching for some minutes, I found this answer inside Stack Overflow site.

So the solution for my problem is, just use install --reinstall [package-name] argument when running apt-get, it will just reinstall you desired package without purging and downloading it back, so here is full command that solved my problem :

sudo apt-get install --reinstall libc6-dev-i386

Solution 2

The package libc6-dev is required to compile anything, and so most, if not all, development packages depend on that package. If you remove libc6-dev, then those headers will get removed as well (along with some of the libraries themselves, if nothing else depends on those libraries and were automatically installed).

Removing and reinstalling this package probably won't help you in compiling 32-bit programs from a 64-bit Ubuntu, since this package is for compiling 64-bit programs. Instead, make sure that libc6-dev-i386 is installed. If you are still getting an error, create a new question and post the error message there.

How about it want to remove nvidia's driver too?

[saiarcot895]

nvidia-331 depends on libc6-dev (and on linux-libc-dev; don't ask me why). You can view this information by typing in apt-cache depends nvidia-331.

Thank you very much for willing your time for me, and I already answered my question. :) Thank you for apt-cache depends [package-name] command, I never knew that.

[mchid]

did that solve your problem compiling?

[Mohd Shahril]

yes it's, gcc don't produce error anymore with -m32 argument after reinstall libc6-dev-i386 using above method.

@mchid, actually I can't, system said only 2 days after posting I'm allowed to accept my own answer. By the way, thanks for the tip.

The following packages have unmet dependencies: libc6-dev : Depends: libc6 (= 2.15-0ubuntu10.12) but 2.19-0ubuntu6 is to be installed Depends: libc-dev-bin (= 2.15-0ubuntu10.12) Recommends: gcc but it is not going to be installed or c-compiler E: Unable to correct problems, you have held broken packages.
