I had Picasa 3,6 running beautifully under Lucid, after following this post: http://www.webupd8.org/2010/04/how-t...in-ubuntu.html
Later, I made the grievous error of moving my /home directory to an ntfs partition. Realizing that it had destroyed all the file ownership of my files (somehow made them all root's), I moved back to ext3 and chown'ed the whole directory back to my ownership. It fixed most problems, except Picasa now won't run.
I've tried removing wine and picasa, reinstalling to no avail. One symptom is that I keep getting these gpg errors when I attempt to add the Google Linux repo's key:
gpg: no writable keyring found: eof
gpg: error reading `-': general error
gpg: import from `-' failed: general error
The contents of my .gnupg directory are all owned by me, and are:
gpg.conf, pubring.gpg, secring.gpg, trustdb.gpg
I'm clueless.... anyone have suggestions? I miss Picasa!
