ADDITIONAL INFORMATION:

#2

testing in the sdk settings, it’s the mersdk@127.0.0.1 connection that fails. the vmshare private keys are new, maybe residual config?

mersdk@127.0.0.1: Permission denied (publickey).

ummm.

#3

What operating system are you using? Are you using Docker or VirtualBox based build engine? Are you sure that the build engine is actually running?

#4

Ubuntu 22/jammy virtualbox. And, of course, the engine is running. I always start it by hand before the IDE. I looked at the authorized key for mersdk … is it possible it didn’t get set correctly in the virtual image? If so, is that editable?

#5

It was because ssh required a confirmation before connecting:

$ ssh -p 2222 -i ~/SailfishOS/vmshare/ssh/private_keys/sdk mersdk@localhost
The authenticity of host '[localhost]:2222 ([127.0.0.1]:2222)' can't be established.
ED25519 key fingerprint is SHA256:M0/8Gxj2TSEihduJj/FtNHlYzLEsRX4hLVp2T010M2U.
This key is not known by any other names
Are you sure you want to continue connecting (yes/no/[fingerprint])? yes

Doing it by hand/cli solved the issue.

#6

Sigh, so now it compiles but it’s not gotten faster. I’ve been waiting 30 minutes for this compile to finish. It’s a big one, but yesterday, clean compile was done in 10 minutes. (cmake on the machine with same code, 2 minutes). argh.
EDIT: Over 40 minutes. this is fugged. wtf.
