I am running Ubuntu 21.04 with sky for linux. Since today `sudo apt update` started has been complaining in skypeforlinux as 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://repo.skype.com/deb stable InRelease: The following signatures were invalid: EXPKEYSIG 1F3045A5DF7587C3 Skype Linux Client Repository W: Failed to fetch https://repo.skype.com/deb/dists/stable/InRelease The following signatures were invalid: EXPKEYSIG 1F3045A5DF7587C3 Skype Linux Client Repository W: Some index files failed to download. They have been ignored, or old ones used instead.
When trying to list the trusted keys with `sudo apt-key list`, I can see the key for Skype Linux Client Repository is expired today.
Warning: apt-key is deprecated. Manage keyring files in trusted.gpg.d instead (see apt-key(8)).

Any updates available in this? Thanks.
