Problems installing Anaconda3-2020.07-Linux-x86_64

[Jeffrey Layton]

Hello

I just installed Ubuntu 20.04 on a system and downloaded the latest community build of Anaconda (2020.07). I got a permission error while installing.

...

Anaconda3 will now be installed into this location:
/home/laytonjb/anaconda3

  - Press ENTER to confirm the location
  - Press CTRL-C to abort the installation
  - Or specify a different location below

[/home/laytonjb/anaconda3] >>>
PREFIX=/home/laytonjb/anaconda3
Unpacking payload ...
Anaconda3-2020.07-Linux-x86_64.sh: 409: /home/laytonjb/anaconda3/conda.exe: Permission denied

Anaconda3-2020.07-Linux-x86_64.sh: 411: /home/laytonjb/anaconda3/conda.exe: Permission denied

I checked the permissions on the directory anaconda3

$ ls -asltar
total 112
...
 4 drwxrwxr-x  2 laytonjb laytonjb  4096 Nov 12 11:12 anaconda3

I also check the permissions on conda.exe:

$ ls -lstar anaconda3/
total 14464
    4 drwxr-xr-x 17 laytonjb laytonjb     4096 Nov 12 11:12 ..
    4 drwxrwxr-x  2 laytonjb laytonjb     4096 Nov 12 11:12 .
14456 -rwxrwxr-x  1 laytonjb laytonjb 14802312 Nov 12 11:12 conda.exe

I've never had a problem installing Anaconda so I'm surprised this happened. Any suggestions?

Thanks!

Jeff

Is your home directory on a mount of some type?

No - it's a local drive.

For posterity, I thought I would post the answer. I didn't know that by default Xubuntu mounts drives with "noexec". This prevents executables from being run on that drive. For me /home was a separate drive and was being mounted with noexec so the Anaconda installed could not run. I had to explicitly mount the drive with "exec" so I could run executables.

I didn't find any documentation on this but found it accidentally by looking at the mount options and noticing "noexec".
