Can't upgrade to os883 official from XO 1.75

[Gonzalo Odiard]

Are you sure it's a XO-1.75?
If yes, may you have a very old testing release (I don't know why look for
python 2.6)
Please tell me what image are you using. (You can look in the control panel
-> about my computer)

You can try flash the xo (after doing a backup)
