I'm guessing it gets created early and then virtualbox drops privileges before opening the file: # ls -l /proc/16866/auxv -r-------- 1 root root 0 Jul 8 16:55 /proc/16866/auxv Change History comment:1 Changed 19 months ago by _ This is silly. It complains but does not say what the file is. PLEASE either fix the message or remove it altogether. comment:2 Changed 19 months ago by frank could not open file for reading permission denied To be able to fix this we would require instructions how to reproduce. comment:3 Changed 19 months ago by groovix I am seeing the same message: just run virtualbox as a normal user from the command line and you'll see the message: Error opening file for reading: Permission denied This is on Ubuntu 12.04. I haven't tried any other oses. ls -l /proc/self/auxv shows: -r-------- 1 myusername myusername 0 Mar 12 12:45 /proc/self/auxv and I cannot chmod that file as myusername or root (although the permissions indicate that I should be able to read it as is) comment:4 Changed 19 months ago by frank Sorry, I don't see the message. The /proc/self/auxv file is present here as well with the same permissions. There is no code in VirtualBox on Linux hosts which tries to access this file, check the source code yourself. And doing strace here I don't see any attempt to access this file either. So I guess that it's some library used by VirtualBox which does this access. comment:5 Changed 19 months ago by groovix When I made my comment I didn't realize /proc/self is a link specific to each process, so after finding the virtualbox pi

How permission denied to set setguid for uwsgi on Ubuntu ? python uwsgi share|improve this question asked Oct 14 '15 at 4:29 Aleksandr 216 Is there something specific that makes you think it's a sticky-bit problem, rather than a more typical owner/group permissioning problem? –John Mee Oct 14 '15 at 4:37 add a comment| 1 Answer 1 active oldest votes up vote 0 down vote Check the owners and permissions on the files that it is trying to file for reading access. what user:group is uwsgi running as? what user:group are the files it is trying to access? You can set the former in the uwsgi config ini via: uid = john gid = www-data And you can check the latter with ls -al eg: Johns-iMac:latest johnmee$ ls -al total 96 -rw-r--r-- 1 johnmee staff 2316 13 Oct 10:15 blog.py drwxr-xr-x 46 johnmee staff 1564 29 May 2011 meejinnz drwxr-xr-x 15 johnmee staff 510 14 Oct 15:29 pages -rw-r--r-- 1 johnmee staff 11 6 Oct 10:35 settings.ini drwxr-xr-x 6 johnmee staff 204 7 Oct 19:20 static drwxr-xr-x 7 johnmee staff 238 13 Oct 18:08 templates As laid out the above may not work because uwsgi is running as john:www-data whereas the files are johnmee:staff. If I were having trouble getting this to work I'd start by putting the files in the same group as the process and setting read permissions appropriately. Ultimately you'll find the best answers in the log files; perhaps located someplace like /var/log/uwsgi/app/john.log. Take care because the responses can change subtly: all the errors look very similar so you can change one thing for the better but not notice the error message has progressed to something else. share|improve this answer edited Oct 14 '15 at 4:50 answered Oct 14 '15 at 4:42 John Mee 21.5k1884120 add a comment| Your Answer draft saved draft discarde
