In salt ssh attributeerror module object attribute fromstringlist error triggers when the salt-master is CentOS6 and the target is CentOS7 (Remotely execute shell commands available here).
The salt-master on CentOS6 would copy ElementTree.py to the minion on CentOS7 but python2.6’s lib cannot run directly on python2.7.
- To overcome the “AttributeError: ‘module’ object has no attribute ‘fromstringlist’ error”,
On the salt-master:
1. Find the thin.py
# find / -name thin.py
/usr/lib/python2.6/site-packages/salt/runners/thin.py
/usr/lib/python2.6/site-packages/salt/utils/thin.py
- In /usr/lib/python2.6/site-packages/salt/utils/thin.py
try:
import xml
HAS_XML = True
except ImportError:
HAS_XML = False
Modify as:
try:
import xml
HAS_XML = False
except ImportError:
HAS_XML = False
2. remove the thin.tgz from cache
# rm /var/cache/salt/master/thin/thin.tgz
3. Perform the salt-ssh command again with -W
( -W for Select a random temp directory to deploy on the remote system. The directory will be cleaned after the execution.)
# salt-ssh -W rnd test.ping
# salt-ssh -W rnd disk.usage
