- Add ownCloud repository for installation of “owncloud-complete-files”, following instructions for Ubuntu 20.04 from: Install package isv:ownCloud:server:10 / owncloud-complete-files
- apt update
- See error:
GPG error: Index of /repositories/isv:/ownCloud:/server:/10/Ubuntu_20.04 InRelease: The following signatures were invalid: EXPKEYSIG 4ABE1AC7557BEFF9 isv:ownCloud OBS Project isv:ownCloud@build.opensuse.org
E: The repository ‘Index of /repositories/isv:/ownCloud:/server:/10/Ubuntu_20.04 InRelease’ is not signed.
Tell us what should happen
I expect to be able to add the repository and run “apt update” without error.
Tell us what happens instead
As mentioned in the steps to reproduce, when following the steps to add the ownCloud server repository, I see an error: “The following signatures were invalid: EXPKEYSIG 4ABE1AC7557BEFF9 isv:ownCloud OBS Project isv:ownCloud@build.opensuse.org”
Note that this is occurring on a machine that already has ownCloud version 10.9.1 installed successfully, that I have just upgraded from Ubuntu 18.04 to version 20.04. That installation was performed through the use of the official repository and I was attempting to switch the repository to the one required from my new operating system version.
