ID: 5435 Title: Fixed "omd update" problems when updating from 1.4.0p17 or older Component: Site Management Level: 2 Class: Bug fix Version: 1.5.0i1 When executing "omd update" as site user to update a site from 1.4.0p17 or older an error could occur blocking the update. The message looks like this: <pre> Traceback (most recent call last): File "/omd/versions/1.4.0p17.cee/bin/omd", line 52, in <module> import tarfile, fnmatch File "/omd/versions/1.4.0p17.cee/lib/python2.7/tarfile.py", line 52, in <module> import copy File "/omd/versions/1.4.0p17.cee/lib/python2.7/copy.py", line 52, in <module> import weakref File "/omd/versions/1.4.0p17.cee/lib/python2.7/weakref.py", line 14, in <module> from _weakref import ( ImportError: cannot import name _remove_dead_weakref </pre> This issue was caused by a mixup of python versions during the update which has been fixed now by using the correct libraries during the update. To workaround this issue, you could run the "omd update" command as root user instead of the site user.
