[SOLVED] How to fix Read-only file system when running cordova run android?

Issue

I am trying to execute

cordova run android --verbose

and I get

spawn EACCES

as an error.

So, I searched online and ran

cordova run android --verbose

and identified the error to be:

Running command: /snap/android-studio/76/android-studio/gradle/gradle-5.1.1/bin/gradle -p /home/extensify/Desktop/Code/cordova/platforms/android wrapper -b /home/extensify/Desktop/Code/cordova/platforms/android/wrapper.gradle
spawn EACCES

Which I read can be fixable by changing permissions for the file /snap/android-studio/76/android-studio/gradle/gradle-5.1.1/bin/gradle

To fix this I tried running

sudo chmod +x /snap/android-studio/76/android-studio/gradle/gradle-5.1.1/bin/gradle

and kept getting

chmod: changing permissions of '/snap/android-studio/76/android-studio/gradle/gradle-5.1.1/bin/gradle': Read-only file system

Which I read can be fixed by remounting my hard drive, which again I tried using several commands, but could not be fixed.

What can I try next?

Solution

This answer is for Ubuntu 18.04

I had this same problem and here's how I fixed them:

1. Remove Android Studio if you installed it using snap.
2. Download Android Studio from their website
3. Extract to /usr/local/ for your user profile, or /opt/ for shared users
4. If you are using a 64-bit machine, run this command to install some required 32-bit packages:

sudo apt-get install libc6:i386 libncurses5:i386 libstdc++6:i386 lib32z1 libbz2-1.0:i386

5. Install KVM, add yourself to group kvm
6. Open a terminal, navigate to the android-studio/bin/ directory, and execute ./studio.sh
7. Run through the installation and make sure you install API Level 28 (Android 9.0 Pie) in SDK Platform
8. Add the following directories to $PATH:
   • /opt/android-studio/gradle/gradle-{version}/bin or /usr/local/android-studio/gradle/gradle-{version}/bin
   • /opt/android-studio/jre/bin or /usr/local/android-studio/jre/bin
   • /home/{name}/Android/Sdk/platform-tools
   • /home/{name}/Android/Sdk/tools/bin
   • /home/{name}/Android/Sdk/emulator/bin
9. Create a virtual device using Android Studio
10. List virtual devices using android list avd
11. Start a virtual device using emulator -avd {deviceName}
12. Run cordova run android, it should work

Recommended:

• Run Android Studio, go to Tools > Create Desktop Entry... so that you can launch Android Studio easily
