Title: /usr/bin/tce-load: line 212: can't create /tmp/appserr: Permission denied
Post by: Adam on April 06, 2017, 07:29:20 AM

I've just created another user "newuser" and getting this error when trying to install new extension.
I don't have this issue using default tc account.

newuser@box:~$ tce-load -wi curl.tcz lynx.tcz
/usr/bin/tce-load: line 212: can't create /tmp/appserr: Permission denied
curl.tcz.dep OK
libssh2.tcz.dep OK

1. Any idea why?
2. What is /tmp/appserr? I found this on line 40 & 212 in /usr/bin/tce-load.

Does your "newuser" has sudo permission ?

Thanks polikuo for your response.
Yes, it does.

What is /tmp/appserr?

It's a log file for tce-load to check whether an extension was mounted correctly.

Perhaps you had ran tce-load as tc before switching to "newuser"

Since the file was created before switching to superuser, (permission rw-r--r-- tc:staff)
making the file unwritable for "newuser".

A bug for tce-load I think, it woud be better if the permission was set to rw-rw-r-- root:staff

Just delete the file and it should be good to go.  ;)
