<p style="margin-bottom:0in;line-height:100%"><font size="2">Hi All</font></p><p style="margin-bottom:0in;line-height:100%"><font size="2">I was trying to install python 3.6, which I think was installed without
problem. Now I get a "red circle with horizontal white line"
in the taskbar at the top, and the error message "An error
occurred when checking for updates". My computer works fine
otherwise without a problem, except that the little red circle is
always there on the top. I tried “<font color="#0000cc">sudo
</font><font color="#0000cc">apt-get
-f install, </font><font color="#0000cc">sudo
</font><font color="#0000cc">apt-get
update, </font><font color="#0000cc">sudo
</font><font color="#0000cc">apt-get
upgrade</font>” commands without any success. I also removed python 3.6, still the error exists. Could anyone
guide me how to fix this error. Here is the output of the upgrade
command-</font></p><font size="2">
