Hi, The problem goes back for about a month.. The problem is resulting for a series of events so I think it might be useful to know in details to provide solutions.
First I switched to Ubuntu Main Repo server from Bangladesh Repo server (since there is no real Repo server in Bangladesh) at first it worked fine for about a week or two. then I started getting "The following signatures were invalid: BADSIG 40976EAF437D05B5" > so I tried removing the signature and adding it back (removed the signature using source list on adept) then tried to export the key $gpg -recv-keys 40976EAF437D05B5 > gpg: can't open `40976EAF437D05B5' > I tried switching to different Repo server and apt-get update... currently my repo server is directed to tw.. http://debian.nctu.edu.twintrepid I can update & install packages (but understandably getting no authentication) W: GPG error: http://debian.nctu.edu.tw intrepid Release: The following > signatures couldn't be verified because the public key is not available: > NO_PUBKEY 40976EAF437D05B5 > any suggestions?? I wish google was more spot on the first time I was googling.. it did not return any useful solutions. today I found launchpad bug report on the same bad signature problem. there are different solutions that worked for some while failed for others... https://bugs.launchpad.net/ubuntu/+source/apt/+bug/24061 any way can anyone help me add the signature back? -- Thanking you Shahriar Volunteer, Bangladesh Linux Users Alliance http://linux.org.bd http://forum.linux.org.bd Marketing & Contents Officer, Ubuntu Bangladesh http://www.ubuntu-bd.org Endorsement: আমাদের প্রযুক্তি ফোরাম http://forum.amaderprojukti.com/ and মুক্ত.অর্গ http://mukto.org -- Ubuntu Bangladesh mailing list ubuntu-bd@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bd
