Using Zynthian

Sorry, it seems like I haven’t used Github for so long, I can’t get past the 2 factor authentication..

As described in the title, I get a 500 Internal Server Error after login to webconf. This is only for the root directory and /sw-repos/ AFAICT. Log shows:

I’m on oram development branch. I don’t know how I can see the versions from the webconf since I’m not able to load that page. Any idea on how I can fix this?

Could you please explain the circumstances where this occurs? Are you trying to run an update, on your Zynthian or are you trying to actually perform these git actions yourself?

3

I have no clue as to whether or not this is a good idea, but have you tried doing what the program suggested (twice):

Thank you for your reply. This happens when I try to access Webconf via the web browser, just after login. It happens every time.

It has been like this for a while, not sure when it occurred the first time. I have since the first occurrence run update_zynthian.sh to update the system, which works fine.

It (of course) originates from the /zynthian/zynthian-sys/ directory being owned by the zynthian user. I could try with the command that is suggested in the output, and that would probably solve the issue.

What I am certain of is that I haven’t caused the issue myself by changing permissions or something like that, so I just want to make sure that things are as they should. When checking ownership of the other directories in the /zynthian dir, it looks like this:

drwxr-xr-x 14 root     root     4096 Nov 22 21:01 zynthian-webconf

That zynthian-my-data/ and config/ are owned by the zynthian user is perhaps more understandable, but maybe not the zynthian-sys/ one. Is it just my system that looks like this? Should I do a chown -R or the git command..?

Well, if it’s any help, here’s my system, screencap of webconf with ssh to root in front of it:

It’s a fairly fresh download of Oram.

That definitely helped, thank you! :grin:

I chown’ed the directories to root and the problem disappeared. Wonder what caused it to change owner, but I guess I’ll never know :flushed_face:

Thanks again!
