Miguel Espeso's questions

I tried to install Android Studio but it gave me several problems. Among them is that they told me that it need Java 8 while on my PC Java 11 is installed.
When I run java -version, the result is the following:

java version "11.0.2" 2018-10-16 LTS Java (TM) SE Runtime Environment
18.9 (build 11.0.2 + 7-LTS) Java HotSpot (TM) 64-Bit Server VM 18.9 (build 11.0.2 + 7-LTS, mixed mode)

I see that java is in /usr/bin, in fact there are several java folder/files:

java, javac, javadoc, javafxpackager, javah, javap, javapackager, javaws

How should I remove java in order to install Java 8 and be able to install Android Studio correctly?

Output of ls -l /usr/bin/java:

lrwxrwxrwx 1 root root 22 feb 5 18:56 /usr/bin/java -> /etc/alternatives/java

Output of ls -l /etc/alternatives/java:

lrwxrwxrwx 1 root root 36 feb 16 23:33 /etc/alternatives/java -> /usr/lib/jvm/java-11-oracle/bin/java

I have tried several commands, but the problem is that I do not know exactly how to install it. On the other hand, when I search for Java in "UBUNTU SOFTWARE", Java does not appear.

I have installed Android Studio with the idea of developing applications with Cordova and Phonegap thanks to the help of my partner @karel who showed me this question: How to install Android Studio on Ubuntu? I followed the instructions exactly, but even so I have several errors. When you start Android Studio with the following command, sudo -E /opt/google/android-studio/bin/studio.sh this shows the first error:

Gtk-Message: 09:07:14.283: Failed to load module "canberra-gtk-module"

(java:13968): IBUS-WARNING **: 09:07:14.566: 
The owner of /home/miguel/.config/ibus/bus is not root!

I installed the SDK, (I think I installed the necessary ones) and when I returned to a Cordova project, and I ran cordova requirements to see if everything was OK, the result was the following:

Android Studio project detected

Java JDK: installed 11.0.2

What did I do wrong? What can I do to correct this and be able to run my applications on Cordova and Phonegap?

I have managed to install the Android SDK thanks to the response of the user @Kin. I only have one question, is it necessary to install eclipse to develop with cordova and Phonegap?

I wanted to install mysql on my laptop to use in projects where I need a database. I'm confused, because I've seen some questions on this site: How to install mysql on Ubuntu 16.04 But I do not know where to find mysql. Can you tell me the steps to follow? Thank you.

I got to install Ubuntu 18.04 on my ASUS F556UJ laptop with the help of the community and follow up queries.

After a while using with the mouse, a few days ago the mouse broke and I had to use the "touch panel". I discovered that the "second button" function used to cut and paste among other things, does not work on the touch panel.

I have consulted ASUS , but they tell me that they do not have support for Ubuntu, which I already knew.

I have tried to fix it from: configure >> Devices >> Mouse and touchpad, but there is no way to solve it. Is there any way to fix this ?

I installed Virtual-Box in Ubuntu 18.04 from the "ubuntu software" store My laptop is an Asus, 8GB RAM and for now it works well. I am trying to install Kaly Linux in Virtual-Box with the following configuration: 4 GB RAM, 16 GB hard drive. And the partitions created a swap of 512 MG, and the rest I leave it for root.

When the installation starts, the laptop is completely blocked, it freezes and I need to turn off the button, to restart it again.

This has happened to me the 4 times I've tried this morning, in the afternoon I'm trying to find a question here like mine, without success.

Any idea why this happens?

Would it be better to install from the terminal to avoid errors? The image I downloaded from Kaly was the one I showed in the capture. Thank you

I want to see where PHP is, because I've found it in /etc/php5/apache2/php.ini., And it's not there. I do not know which is the best way to install it, since I never did it, and I did not want to put it in the wrong place, that is why I come to you. Thank you.

EDITO: I'm creating a website and the images they gave me are too big. In Windows I used Photoshop to reduce the size, or maybe it is better to say scale the size, because I want to keep the whole image, in a smaller size, to be able to put them in the grid.

I ask for advice here, because I never use an editor in Ubuntu, I see all that there is in: Ubuntu Software, but not what would be the most appropriate for professional image editing, in the creation of a website, and to be able to give the best possible appearance to the images. In this case, reduce the size of some images, or perhaps it would be better to say, re-dimension. Thank you.

I'm trying to install Ubuntu 18.04 on my ASUS F556U laptop without success. I already asked other questions on the subject, thinking that the problems were by UEFI mode. Well surpassed that, I already discovered that the problem is of the laptop, a professional I assure to me that it can be problem of Targeta Grafica, is not compatible with Linux. Well, since I can not install 18.04 install 16.04 but when updating it is broken and there is an error in the screen that I can not distinguish well, which I show: PCIe Bus Error: severity = Corrected, type = Physical Layer, id

When installing 16.04 it works perfectly, but it notifies me of an internal error, to send to Ubuntu. The error I show you in a screenshot. I hope someone can help me, maybe there is already a question on the subject on this site, but maybe I did not know how to look for it. I've been with the problem for almost two months, and now I can not buy another laptop, if it does not work for Linux. I already tried other Linux distributions, and it gives me the same error. Now it gives me another problem, a message saying that I have little space in the root file system, only 924 MB, when I leave 150 GB. If you can give me an idea, thank you. I show you screenshots of the errors you asked me to send to Ubuntu

EDITO: *

The partner @oldfred helped me with his comments, but ASUS does not give me support for UBUNTU, to be able to update the BIOS. I do not know if I am adding PCI = NOMSI correctly, because when I update, the error of the first image that I am attaching is shown on the screen. If you could help me, it is very frustrating to have a laptop with which I must work and not be able to install Ubuntu. Well, I think the reality is that Ubuntu is not installed, because Asus is giving me a lot of war.

I have an Asus F556U series, 8G of RAM, and trying to install Ubuntu 18.04 from USB when I get to the part where it shows the image, the installation freezes. I've been half an hour now and continue as you see the image. Is there anything special I need to do to install Ubuntu on Asus? Thank you

Install ubuntu 17.10 with usb in UEFI mode. I followed the instructions for other questions on the site that I kindly offered @karel for the installation.

and as I was wrong I followed the steps that are offered in the link: 16.04 new installation gives grub-efi-amd64-signed failed installation /target/ ubuntu 16.04 at the end Everything worked perfectly. I get the complete installation and at the time of updating, it gives a series of errors that I do not have time to see, and the laptop goes to airplane mode, without starting the system. Then update according to this question: How do I update Ubuntu 17.10 to 18.04? but after finishing the installation and restarting, the screen went black and Ubuntu 18.04 did not appear. Perform the installation again following the instructions and steps above and run the following commands:

sudo su;
efi = "/target/boot/efi/EFI"; \
if [[-e "$ {efi}/boot"]]; then \
echo "Backup:"; \
 mv -v "$ {efi}/boot/" "$ {efi}/boot-bak - $ (lsb_release -cs)"; \
fi; \
echo "Copy:"; \
cp -va "$ {efi}/ubuntu" "$ {efi}/boot"; \
arch = "$ (ls -1 {efi} /ubuntu/shim*.efi)"; \
arch = "$ {arch # * shim}"; \
arch = "$ {arch% .efi}"; \
cp -v "$ {efi}/boot/shim $ {arch} .efi" "$ {efi}/boot/boot $ {arch} .efi";

But the console gives the error:

cp: you can not perform "stat" on /target/boot/efi/EFI/ubuntu: there is no file or directory.

What am I doing wrong or what I still have to do? Thank you.

Any idea what I'm doing wrong?
I have tried to install Node.js and it also gave me error:
          npm update check failed │
│ Try running with sudo or get access │
│ to the local update config store via │

Try cleaning the cache, but the command did not work with the command sudo npm cache clean -f I do not know what else I can do to correct errors. Thank you.

I'm installing Rethinkdb in Lubuntu 16.04, since in Ubuntu 18.04 I could not get it, and everything worked perfectly with the instructions my colleagues showed me. He did the compilation perfectly until I started building the server in the following way:

cd rethinkdb-2.3.6
./configure --allow-fetch
make
sudo make install

When I get to sudo install make I get the following error, which I do not know why it is. If you can give me an idea of where it comes from and how to solve it ... Thank you.

~/rethinkdb-2.3.6$ sudo make install
[1/9] LD build/release/rethinkdb
/rethinkdb-2.3.6/build/external/openssl_1.0.1t/lib/libssl.a(ssl_algs.o):  reference without defining the symbol'EVP_dss1@@OPENSSL_1.0.0'

make[1]: *** [build/release/rethinkdb] Error 1
Makefile: 52: failure in the instructions for the 'make' objective
make: *** [make] Error 2

I have installed Rethinkdb for a project I am doing with Node.js following the steps of the Rethinkdb website.

But after executing rethinkdb in terminal inside the folder /rethinkdb-2.3.6, it returns:

rethinkdb: order not found

As I say, I followed the steps of the web, on another occasion I worked, but in this one in Ubuntu 18.04 LTS I did not get installed.

Is there any other documentation that I can follow for the correct installation?

Forgive the syntax, I must use the translator. Thank you.

EDIT:

When I try sudo apt-get install rethinkdb, it returns:

package not found

I saw something about "brew" to install rethinkdb on Mac, I do not know if it can be an alternative for Ubuntu.

I have installed Ubuntu 18.04 LTS I used to use Visual Studio Code for my projects but the problem is that it is very slow. It hooks or locks, I do not know how to put it so that they understand me, because I use the translator and I do not know what will be better. The fact is that it is very bad, both in this version and in 16.04. I also have it in Windows and it works perfectly. Sometimes it crashes, blocking all processes and denying access to the computer. Does that have something to do with Ubuntu, should I optimize it in any way? If you give me some idea, well, as I said, I got used to Visual Studio and I tried Sublime text-3 which is much better, but I should get used to it and I do not like it very much. Forgive the syntax, I must use the translator. Thank you.

I need a compatible version of Ubuntu for my computer that has only 248 MB of RAM. Would it be possible to remove Windows XP?

I cannot find a way to install Avast Internet Security 6.0.1367.exe from the exe file directly.

I would like to know how to install it on my computer, to know the right commands to install it from terminal.
