When trying to do normal updates in Mint 22.3 via the Update Manager UI, the cache update gets stuck on insync for a while.
Should I remove it from the repository, or will it be fixed sometime? For the time being, I’ve disabled it so updates can run.
Thank you for reporting this and my apologies for the trouble. Allow me to raise this to our Linux Team for advise!
On a whim, I tried to re-enable the InSync repository and it now works. Looks like it is pointing to a new location “https://fastly.linuxmint.io”.
Hi @BrianG, the issue is likely network-related. Our engineer checked our repositories to make sure, and there are no known issues at the moment. 
Correct, it works fine now. Like I said, the non-working repository used to be:
“apt.insync.io”
But the current working one is now:
“fastly.linuxmint.io”
