It seems that the signing key for the Linux .rpm packages (and associated repo) has expired:
peter@tumbleweed:~/Downloads> sudo rpm -i insync-3.9.6.60027-fc42.x86_64.rpm
[sudo] password for root:
error: Key a684470caccaf35c (Insynchq Inc services@insynchq.com) expired on 2024-09-08 08:24:38
The particular public key was installed on my machine in june 2024. I have also tried to get a possibly new key following the instructions on Linux - Download Insync, but that seems to be the same expired key:
peter@tumbleweed:~/Downloads> sudo rpm --import https://d2t3ff60b2tol4.cloudfront.net/repomd.xml.key
peter@sweetwater:~/Downloads> sudo rpm -i insync-3.9.6.60027-fc42.x86_64.rpm
error: Key a684470caccaf35c (Insynchq Inc services@insynchq.com) expired on 2024-09-08 08:24:38
error: Key a684470caccaf35c (Insynchq Inc services@insynchq.com) expired on 2024-09-08 08:24:38
It would be nice with a new signing key. Meanwhile, can anybody help with a work-around?
