CMake error while installing Bullet Physics (PYTHON_LIBRARY set to NOTFOUND)

Hello everyone I’m trying to install Bullet Physics in my Ubuntu 18.04 LTS.

I managed to install cmake successfully, but as soon as I try to run

./build_cmake_pybullet_double.sh 

it shows me the error

CMake Error: The following variables are used in this project, but they are set to NOTFOUND. Please set them or make sure they are set and tested correctly in the CMake files: PYTHON_LIBRARY (ADVANCED) 

I already installed python3-pip and other libraries, but why is this error happening?

(In usr/lib there are the following folders python2.7, python3, python3.6, python3.7)

Thanks in advance!

I am brand new to Drupal. I have noticed that there are security updates avaialble for my version. When I select the first item requiring an update and select download I get the following error HTTP error 0 occurred when trying to fetch https://ftp.drupal.org/files/projects/mimemail-7.x-1.1.tar.gz.

make failed when installing hplip

I downloaded the latest version of hplip (3.19.5) from here. Following the installation instructions, I ran:

sh hplip-3.19.5.run 

It all worked well until the last step, where I got the following output:

PRE-BUILD COMMANDS ------------------ OK   BUILD AND INSTALL ----------------- Running './configure --with-hpppddir=/usr/share/ppd/HP --libdir=/usr/lib --prefix=/usr --enable-qt4 --disable-qt5 --enable-doc-build --disable-cups-ppd-install --disable-foomatic-drv-install --disable-libusb01_build --disable-foomatic-ppd-install --disable-hpijs-install --disable-class-driver --disable-udev_sysfs_rules --disable-policykit --enable-cups-drv-install --enable-hpcups-install --enable-network-build --enable-dbus-build --enable-scan-build --enable-fax-build --enable-apparmor_build' Please wait, this may take several minutes... Command completed successfully.  Running 'make clean' Please wait, this may take several minutes... Command completed successfully.

Indeed, when I run make I get:

Installing LineageOS OTA update from the recovery manually

I installed LineageOS on my OnePlus One, and today I got the latest nightly. The OTA update system downloaded the file, and I clicked install. However, it says

Note: This feature requires a compatible recovery or you will have to install it manually.

Then it sends me to recovery and nothing happens.

Can I get some help as to how to update?

Error Installing System Update

How can I fix my phone so that it will boot up again like normal?

When it tries to start up, I see the Samsung Galaxy S9 Secured by Knox Powered by android screen. After this screen vibrates, it restarts and returns to the same screen. Here’s a picture of the screen. enter image description here

If I press the volume up, power and button below the volume, then it will show the same Samsung Galaxy S9 Secured by Knox Powered by android screen. After that, it will show a Installing system update screen. Then it will progress to 28% and restart. Here’s a picture of the screen below. enter image description here

I have installed ubuntu 19.04 and now tried to install Quogir theme from https://www.addictivetips.com/ubuntu-linux-tips/install-the-qogir-gtk-theme-on-linux/. After downloading and installing it, I tried to install the images through ./Install -i command which is asking root permission. But after putting root password, it is showing somthing like this:

[ trusted ] specify the root password : \n running: sudo apt install sassc  Reading package lists... Done:  Building dependency tree        Reading state information... Done The following additional packages will be installed:   libsass1 The following NEW packages will be installed:   libsass1 sassc 0 upgraded, 2 newly installed, 0 to remove and 0 not upgraded. Need to get 773 kB of archives. After this operation, 2,753 kB of additional disk space will be used. Do you want to continue? [Y/n] Abort. \n Operation canceled  Bye 

Now, I can see the Qogir themes in my unity-tweak but the background images are missing. Please give your suggestion about this problem.

Installing MongoDB on RHEL 8 | AWS EC2 — Failed to synchronize cache

I am attempting to install MongoDB on my RedHat 8 | AWS EC2 instance …

/etc/yum.repos.d/mongodb-org-4.0.repo

Then … yum repolist

Possibly RHEL 8 being a new release is causing issues?

apk files not installing in samsung s9 plus

0

I recently got a HTC One M9, and I wanted to replace it’s gallery with my old phone’s gallery because I loved one of the filters that it had. This led to me having to download a third party APK file, but when I tried to install it, it just gave me an error that said “App not installed.” I first thought it’s because it won’t install because the current gallery is still on my phone, but after disabling the app, I still get the error message. Is there any way I can fix this?

The APK file is lucky patcher if that helps
