signature verification error for wine - index files failed to download - changing mirror doesn't help
Solution 1
Note that after adding the new keyfile, it is better to use apt update
rather than apt-get update
, as it will prompt you to accept the changes.
So in full:
wget -nc https://dl.winehq.org/wine-builds/winehq.key && sudo apt-key add winehq.key && sudo apt update
Solution 2
As of 2018-12-19 08:07 there is a new winehq.key
keyfile as mentioned here.
Download the new repository key and add it to the list of trusted keys:
cd /tmp
wget -nc https://dl.winehq.org/wine-builds/winehq.key
sudo apt-key add winehq.key
sudo apt update
As mentioned by @jason-hunter in a comment, apt update
will ask if you accept the changes in the repository, whereas apt-get update
will show an error and fail.
Solution 3
Inspecting https://dl.winehq.org/wine-builds/, there's a new file winehq.key
. Try using that instead, as its fingerprint seems to match the error:
# curl -sL "https://dl.winehq.org/wine-builds/Release.key" | gpg --dry-run --import --verbose
gpg: pub rsa4096/818A435C5FCBF54A 2015-11-23 Sebastian Lackner (WineHQ packages) <[email protected]>
gpg: Total number processed: 1
# curl -sL "https://dl.winehq.org/wine-builds/winehq.key" | gpg --dry-run --import --verbose
gpg: pub rsa3072/76F1A20FF987672F 2018-12-10 WineHQ packages <[email protected]>
gpg: key 76F1A20FF987672F: 1 signature not checked due to a missing key
gpg: Total number processed: 1
Solution 4
This command worked for me:
wget -nc https://dl.winehq.org/wine-builds/winehq.key && apt-key add winehq.key

When I
sudo apt-get update
I get the error shown below.W: An error occurred during the signature verification. The repository is not updated and the previous index files will be used. GPG error: https://dl.winehq.org/wine-builds/ubuntu bionic InRelease: The following signatures couldn't be verified because the public key is not available: NO_PUBKEY 76F1A20FF987672F W: Failed to fetch https://dl.winehq.org/wine-builds/ubuntu/dists/bionic/InRelease The following signatures couldn't be verified because the public key is not available: NO_PUBKEY 76F1A20FF987672F W: Some index files failed to download. They have been ignored, or old ones used instead.
So I go ahead and change my mirror as suggested by this Ask Ubuntu answer. Then I restart the computer. And I still get the same error above when I
sudo apt-get update
.Let's try and reinstall the keys.
$ wget -nc https://dl.winehq.org/wine-builds/Release.key && sudo apt-key add Release.key File ‘Release.key’ already there; not retrieving. OK
And I might as well
ping -c3 archive.ubuntu.com
and my packet loss is 0%. What else do I need to do?-
Admin over 5 yearsIt looks like the new update for wine is signed with a different key than the Release.key they are hosting...

Display name over 5 yearsI also added the repository
sudo apt-add-repository 'deb https://dl.winehq.org/wine-builds/ubuntu/ bionic main'
and this solution worked. As mentioned you must usesudo apt update
and notsudo apt-get update
.apt
forces you to explicitly accept, whereasapt-get
does not and will yield an error. If you have other versions of Ubuntu your repository to add can be found here wiki.winehq.org/Ubuntu -
kcpr over 5 yearsI would consider adding
rm winehq.key
or saving the file to the/temp
at the beginning. Thanks anyway!
