I had kind of a similar problem yesterday which popped out of the blue. Mongodb failed to start and complained about
WiredTiger error (-31802) [1589317956:154007][4136:0x7f1220932d00], txn-recover: unsupported WiredTiger file version: this build only supports major/minor versions up to 1/0, and the file is version 2/0According to the snap logs (snap changes) this problem came through a snap update yesterday at 21:11 CEST and it vanished by itself with the next snap update at 05:03 CEST.
So I think the first update had a problem and it was fixed with the second update… I’m now searching the Internet for a confirmation of this Bug and why it happend and what has been changed to make it disapear.
Does it help to refresh your snap package?
