I’m trying to install insync on Debian Trixie and the installation fails.
The install fails when updating from Bookworm or on a fresh install on Trixie. What seems to be happening is the installer is changing the trusted key and the changed key isn’t recognized.
I also tried copying over the key from a working Bookworm installation but the installer modifies it when upgrading to Trixie.
Attached is a screenshot of the install on a fresh install of Trixie.
Sorry for the trouble! Let me forward this to our engineers to check what may be happening.
In the meantime, let me know what this file says: /etc/apt/sources.list.d/insync.list
It should ideally say trixie rather than bookworm. If not, please update it then try the installation again.
Hi Mia,
Any update on when this will be fixed?
Hi @Sam_Crawford! Apologies for the delays. Just checking that your /etc/apt/sources.list.d/insync.list file says trixie, correct?
Hi Mia, I thought I replied to your question a few days ago but maybe I didn’t.
Yes, the insync.list file says trixie.
Can you uninstall Insync (sudo apt remove insync) and then re-install using apt (sudo apt install ./insync_3.9.4.60020-trixie_amd64.deb)
Hi Kurt, I’m still getting the same issue.
It exits with the following message: “Error: Sub-process /usr/bin/dpkg returned an error code (1)”
Is it only me having this problem? This is my attempt this morning to install Insync on a new “trixie” virtual machine. Note: I also was getting the same error attempting to install on an actual installation of trixie too.
sam@debian:~/Downloads$ sudo apt install ./insync_3.9.4.60020-trixie_amd64.deb

Hi @Sam_Crawford! So sorry for not getting back to you sooner. I’ll escalate this to @Kurt_Ko for further investigation.
Thank you for your patience!
@Sam_Crawford Kurt will re-test some things on his end and we’ll update you accordingly. Thank you!
@Kurt_Ko Anything yet?
Can all affected parties share their /var/log/dpkg.log files after trying a fresh installation? Seeing the errors with a bit more detail would definitely help.
Cheers,
H.

Just to confirm Sam’s report here. All you need to do to replicate this is install Debian Trixie using the current version of the installer (https://cdimage.debian.org/cdimage/weekly-builds/amd64/iso-dvd/debian-testing-amd64-DVD-1.iso) and immediately after installation, attempt to install insync. I usually do that by downloading the installer from your site and then using gdebi to install it.
I am following up with @Kurt_Ko for an update. Thanks so much @reis for the information you shared! We really appreciate it.
The solution I used:
cd /var/lib/dpkg/info/
Remove all insync files:
rm insync.*
Ensure you have the correct GPG key from Insync, as apt-key has been discontinued in Debian Trixie. The Insync documentation is currently incorrect. Please run the following command:
sudo gpg --no-default-keyring --keyring /usr/share/keyrings/insync.gpg --keyserver hkp://keyserver.ubuntu.com:80 --recv-keys ACCAF35C
Run the command apt update and check if the error has disappeared. If necessary, reinstall Insync.
Hi Danilo
I tried what you suggested but it’s not working for me. I may have done something wrong.
@mia @Kurt_Ko @bayindirh Any updates to this issue yet?
When I try @Danilo_Arantes suggestion “sudo gpg --no-default-keyring --keyring /usr/share/keyrings/insync.gpg --keyserver hkp://keyserver.ubuntu.com:80 --recv-keys ACCAF35C”, I get the following error:
“gpg: failed to create temporary file ‘/root/.gnupg/.#lk0x00005643d59d5eb0.debian.4684’: No such file or directory
gpg: connecting dirmngr at ‘/root/.gnupg/S.dirmngr’ failed: No such file or directory
gpg: keyserver receive failed: No dirmngr”
Thanks!
Hey! I’ll check back with @Kurt_Ko 
@bayindirh is one of our long-time users 
They’ve really been a blessing to all of us here as they’d share their knowledge whenever possible 
Hi @mia,
Thanks for your kind words. I have seen the post, and will try a clean install when I have time. Currently it’s a bit tight, but will try to keep you updated.
Cheers!
