Hi, I have three computers and two of these, one Linux and one Mac works excellent with Iceberg. But I have a difficult child, one laptop where I can not checkout code from a private github repo. It keeps running into stacktrace, nomatter which strategy I select. Problems does not seem to be connected to versions. I have tried different versions of Pharo images, from 8-stable to 9-bleeding edge. I have ticked the ssh-setting in Pharo for using custom keys and verified that these exists and has right permissions. Checkout from ssh in shell works fine. I have tried these strategies. 1) Using the add-key trick which is referred as a solution on this, like in ssh-add ~/.ssh/id_rsa This always results in stacktrace in Pharo. 2) Checking out as as github-repo with ssh, same problem 3) Checking out as a git-repo, same problem 4) Generated new ssh-keys and tried to setup these as the default keys Same stack trace problem in Pharo. 5) Checking out over https This does not work either. The ssh-checkout box appears in Pharo even though I select this specifically. Checking out over https-does not seem to be working at all? Version on ssh on my laptop is: ssh: OpenSSH_8.1p1, LibreSSL 2.7.3 mac: Catalina 10.15.6 Interesting enough I have the same versions on my working mac. Only difference is that the default ssh-key is with a passphrase on the non-working computer (entering this in the ssh does not help, creating a new ssh-keypair without a passphrase does not make a difference either). ssh_config is also equal on the two computers. Has anybody solved a case like this or has any clues? This beats me :) And when Iceberg is up and running I must say it is really a valuable and nice tool, thx!
