This problem is probably related to: https://bugs.launchpad.net/command-not-found/+bug/1480388
In that case a simple solution is to change a line in /usr/lib/command- not-found from: os.execvp("python3", [sys.argv[0]] + sys.argv) to: os.execvp("/usr/bin/python3", [sys.argv[0]] + sys.argv) -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to python3.3 in Ubuntu. https://bugs.launchpad.net/bugs/1192890 Title: update-manager fails to upgrade from quantal to raring No module named '_sysconfigdata_m' Status in python3.3 package in Ubuntu: Confirmed Status in python3.4 package in Ubuntu: New Bug description: I ran update manager and chose to upgrade to raring. The packages all downloaded. On installation, I repeatedly saw something like this in the console: File "/usr/lib/python3.3/site.py", line 633, in <module> main() File "/usr/lib/python3.3/site.py", line 618, in main known_paths = addusersitepackages(known_paths) File "/usr/lib/python3.3/site.py", line 284, in addusersitepackages user_site = getusersitepackages() File "/usr/lib/python3.3/site.py", line 260, in getusersitepackages user_base = getuserbase() # this will also set USER_BASE File "/usr/lib/python3.3/site.py", line 250, in getuserbase USER_BASE = get_config_var('userbase') File "/usr/lib/python3.3/sysconfig.py", line 610, in get_config_var return get_config_vars().get(name) File "/usr/lib/python3.3/sysconfig.py", line 560, in get_config_vars _init_posix(_CONFIG_VARS) File "/usr/lib/python3.3/sysconfig.py", line 432, in _init_posix from _sysconfigdata import build_time_vars File "/usr/lib/python3.3/_sysconfigdata.py", line 6, in <module> from _sysconfigdata_m import * ImportError: No module named '_sysconfigdata_m' Eventually, update-manager silently exited. Now when I try to start it again from gnome-terminal, I see the above, and update-manager immediately exits. In fact, python3.3 doesn't run, with the same error, and apt-get install python3.3 Results in the same error repeatedly _sysconfigdata_m.py is in http://packages.ubuntu.com/raring/amd64/libpython3.3-minimal/filelist But it wasn't installed, so I installed it by hand using dpkg. python3.3 still doesn't run, but now I apt-get install python3.3 without seeing this error, and all the unconfigured packages from the upgrade get configured. The reporting guidelines don't seem to apply to upgrade issues, but for completeness $ lsb_release -rd Description: Ubuntu 13.04 Release: 13.04 What I expected: I expected update-manager to upgrade my system, or to report that it had failed What happened: update-manager exited, without reporting failure, leaving my system in an unusable state To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/python3.3/+bug/1192890/+subscriptions -- Mailing list: https://launchpad.net/~touch-packages Post to : touch-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~touch-packages More help : https://help.launchpad.net/ListHelp
