I'm trying to use the repo command which I installed via snap on Ubuntu 18.04. Most commands were working okay but when I try to run repo forall I get the follow error:

repo forall -c 'pwd'
Traceback (most recent call last):

 sl = self._semlock = _multiprocessing.SemLock(kind, value, maxvalue)

I looked into this question:

https://stackoverflow.com/questions/2009278/python-multiprocessing-permission-denied

But my /dev/shm directory seems okay:

ls -lad /dev/shm
drwxrwxrwt 2 root root 40 May 26 16:40 /dev/shm

The following commands work fine:

$ cd /dev/shm
$ touch test
$ ls -la test
-rw-rw-r-- 1 myuser myuser 0 May 26 21:00 test

Any other ideas?

Here are my repo version details:

repo version v1.12.37
 (from https://gerrit.googlesource.com/git-repo)
repo launcher version 1.23
 (from /snap/git-repo/18/bin/repo)
git version 2.12.0
Python 2.7.12 (default, Nov 19 2016, 06:48:10) 
[GCC 5.4.0 20160609]

Maybe the problem is coming from around this line of code?

https://github.com/python/cpython/blob/804fcf66559992db9d23695e501c502ab20b7712/Modules/_multiprocessing/semaphore.c#L195

When I write a sample program like so it works fine:

int main(void)
 O_EXCL, 0600, 0);
 if (SEM_FAILED == sem) 
 printf("Create semaphore failed %s, errno = %dn", name, errno);
 else 
 printf("Created semaphore succeededn");
 

 return 0;

So still searching...

Solution is do not use snap to install the repo command. Use apt instead. No idea why.
