Hello Tomeu and all, I just got the chance to try installing socialcalc on the sugar live cd and I have been able to install it properly. Here is the review of the process, might be helpful for other activities also in case anybody faces a similar problem-- 1. Actually, the error which was coming earlier was because of the permission being denied by sugar. So, in order to install any activity one is supposed to use the sudo command to have super user access. I mean, the following command would lead to above mentioned errors--- sugar-install-bundle SocialCalcActivity.xo However, using sudo will resolve the issue-- sudo sugar-install-bundle SocialCalcActivity.xo 2. However, I was unable to install the activity directly from the journal, when we click on the activity bundle in the journal, nothing actually happens. <div class="gmail_quote"> <blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;">Hi, can you check you can write to /home/olpc/Activities? </blockquote><div> Yes, we can write but by using sudo command. </div><blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;"> Regards, Tomeu </blockquote><div> Cheers, VIJIT aka sumit </div></div>
