"exception from gpg: GnuPG exited non-zero" whie upgrading to Precise

[Sergey Zolotarev]

I'm trying to update from Oneiric to Precise. Here's what update-manager -d says after the "Downloading the release upgrade tool" window gets closed:

authenticate 'precise.tar.gz' against 'precise.tar.gz.gpg'
exception from gpg: GnuPG exited non-zero, with code 1
Debug information:

Are you using a proxy server of some sort that would affect the downloading of precise.tar.gz? You should be able to find that file in /tmp/update-manager-w6dStv or if its not there in a folder named similarly if you start the process again. I'd check the size and md5sum of the file to ensure it has not been modified.

I'm having the same issue, but after starting the update-manager with sudo it works.

[Expired for update-manager (Ubuntu) because there has been no activity for 60 days.]

[Hongxin Liang (honnix)]

the same problem for me.

i have both precise.tar.gz and precise.tar.gz.gpg downloaded in to /tmp/update-mange-xxxx.

authentication fails even if i run it manually:

honnix@honnix:/tmp/update-manager-RWxJ3G$ gpg precise.tar.gz.gpg
Detached signature.
Please enter name of data file: precise.tar.gz

i've tried to rebuild cache, but not help

[Hongxin Liang (honnix)]

problem is gone after i switch to us repository. anyway i still doubt it is a problem.

For me this problem was caused by /tmp being mounted as noexec.
