3 baisic problems I am having with F8_x64 ??

[William Case]

Hi;

1) I tried to check for new upgrades this morning and again at noon with
yumex.  Yumex couldn't find a mirror.

"10:42:02 :   --> [Errno -1] Metadata file does not match checksum
10:42:02 : Trying other mirror.
10:42:14 : failure: repodata/comps-f8.xml from updates: [Errno 256] No
more mirrors to try."

2) I keep getting email message from root. I use mutt for this.

Can't connect to the database.
Error: Can't connect to local MySQL server through socket
+'/var/lib/mysql/mysql.sock' (2)
  Is your database installed and up and running?
  Do you have the correct username and password selected in
localconfig?"

I tried to use mySQL Manager to re-setup my mySQL database and got:
"Can't connect to the database.
Error: Can't connect to local MySQL server through socket
+'/var/lib/mysql/mysql.sock' (2)
  Is your database installed and up and running?
  Do you have the correct username and password selected in localconfig?

Could not connect to host 'CASE'.
MySQL Error Nr. 2003
Can't connect to MySQL server on 'CASE' (111)"

3) gnome-keyring-manager keeps asking me for my password.  I have tried
all the fixes e.g. fixing /etc/pam.d/gdm, and deleting ~/gnome2/keyrings
etc.  Nothing works.  I went to bugzilla (I am relatively new at using
bugzilla) and found two or three reported bugs that sound similar but
not the same as my problem.  I was unsure whether I should add a bug or
just add my name to those that are close. ??

I really want to get on with things, so any quick and dirty advice
appreciated.
