view story

http://ubuntuforums.org – Hey I have just installed Ubuntu from a thumb drive today and it has been acting really buggy, some programs dont open all the time and some like the software center never open. I went into the terminal and ran the command gksudo software-center and this is what I got in return. 2012-08-24 22:58:58,911 - softwarecenter.db.database - INFO - open() database: path=None use_axi=True use_agent=True 2012-08-24 22:58:58,913 - softwarecenter.db.database - ERROR - failed to add apt-xapian-index Traceback (most recent call last): File "/usr/share/software-center/softwarecenter/db/database.py&q (Hardware)
