 |
|
I just installed Android Studio via | Code: | sudo emerge -av dev-util/android-studio
|
However, when I try to start it, either via the installed desktop shortcut or via the android-studio command as normal user, a window opens and tells me the following: | Code: | Temp directory '/home/michael/.AndroidStudio3.0/system/tmp' is inaccessible.
If you have modified the 'idea.system.path' property please make sure it is correct,
otherwise please re-install the IDE.
Details: IOException: Cannot run program "/home/michael/.AndroidStudio3.0/system/tmp/idea_tmp_check.sh": error=13, Permission denied |
However, the directory /home/michael/.AndroidStudio3.0/system/tmp/ exists and the permissions are completely right. The only way to start it is via sudo. Any idea why?

What are the permissions and ownership on that directory and its ancestors? How does Android Studio invoke its temporary checker? When you start via sudo, does it use that tmp or a different one? What are the mount options for the filesystem that contains that directory?
As an aside, it seems very questionable to me to be expecting a temporary directory to permit executing scripts. Disallowing that has been standard security practice for years. |

I have no idea.

It uses /root/.AndroidStudio3.0/system/tmp and everything works fine.

| Code: | | /dev/sda3 /home ext4 defaults,noatime,noexec 0 0 |

| You omitted the ancestor directories (showing only the immediate parent), but you did show the problem. This is a bug in Android Studio. It is trying to run code in a directory that is rightly noexec (but wrongly not nodev, though that is for the truly paranoid; noexec covers your most likely problem scenarios), then is surprised when that noexec blocks it from running. You may be able to work around this by setting some environment variable or other parameter to point it to an executable directory. Otherwise, you will need to patch it not to run code in temporary directories. |
