Description of problem: arduino requires write access to /var/lock to access the serial port. Version-Release number of selected component (if applicable): arduino-0021-1.fc14.noarch How reproducible: Run the program Steps to Reproduce: 1. yum install arduino 2. arduino 3. Actual results: Get the following error message check_group_uucp(): error testing lock file creation Error details:Permission deniedcheck_lock_status: No permission to create lock file. Expected results: Lock file should be created. Additional info: In Fedora 13 /var/lock had ownership root:lock and permissions 775. This meant that adding the user to the lock group gave sufficient permissions. Fedora 14 has a /dev/lock/lockdev with the permissions mentioned above. Is there perhaps a change here which means that it should be writing to /dev/lock/lockdev rather than /dev/lock?
I meant /var/lock and /var/lock/lockdev, not /dev/lock and /dev/lock/lockdev
The lock directory has changed for security reasons (see bug #581884). Locking is handled by RXTX, and the directory used is defined in SerialImp.h.
rxtx-2.2-0.3.20100211.fc14 has been submitted as an update for Fedora 14. https://admin.fedoraproject.org/updates/rxtx-2.2-0.3.20100211.fc14

Seems to be fixed. The fix was out incredibly fast. Thanks very much!

I just installed the arduino package on Fedora 14 and am using an Arduino UNO device. When I check installed packages I get : # yum list installed rxtx rxtx.i686 2.2-0.3.20100211.fc14 @updates # yum list installed arduino arduino.noarch 0021-1.fc14 @fedora When launching arduino GUI and trying to upload an arduino sketch to the arduino board I always get an Arduino error message saying that there is an invalid device signature. Starting arduino from the commandline I get : [mb0606 ~]$ arduino WARNING: RXTX Version mismatch Jar version = RXTX-2.2 native lib Version = RXTX-2.2pre2 Could this version mismatch be the root cause for this error ??
I've installed Arduino1.0 on Fedora16 with rxtx 2.2-0.5.20100211 and I've got the same problem.
(In reply to comment #8) > I've installed Arduino1.0 on Fedora16 with rxtx 2.2-0.5.20100211 and I've got > the same problem. When you say Arduino 1.0, do you mean that you downloaded a copy from the arduino.cc website? They bundle their own version of rxtx, which won't include these fixes. You could try Fedora's arduino 1.0 packages from rawhide. See http://arduino.cc/playground/Linux/Fedora.
Yes, I downloaded it from the arduino.cc website because the update's link of my old version points there. Thank you very much Peter Oliver, this runs!!
I downloaded latest Arduino 1.0.4 (because Fedora package is too old for some Arduino boards) and I still get this error: check_group_uucp(): error testing lock file creation Error details:Permission deniedcheck_lock_status: No permission to create lock file. My user is Administrator type and is in dialout group.
And I'm also in "lock" group also...
After changing permissions I got arduino to work because /run/lock had this permissions: drwxr-xr-x. 6 root lock 120 May 17 10:49 lock So even if I was in "lock" group I had only "read" permission. After changing permissios arduino works: sudo chmod 775 /run/lock Hope this helps others.
