Devs Suddenly I can't push to (a non-master branch on) gitlab.haskell.org. In .git/config I have [remote "origin"] url = https://gitlab.haskell.org/ghc/ghc fetch = +refs/heads/*:refs/remotes/origin/* [branch "master"] remote = origin merge = refs/heads/master An attempt to push leads to a request for a username. If I enter one, a request for a password. simonpj@MSRC-3645512:~/code/HEAD$ git push origin wip/T16735 Username for 'https://gitlab.haskell.org': C-c C-c I thought I had SSH keys uploaded. But in fact I found that my id_rsa.pub was a bit different to the one in gitlab. Not sure _how_ that happened, or why it hasn't bitten before. So I uploaded a new id_rsa.pub key. Same behaviour. So I tried ssh -v gitlab.haskell.org, and got the output below. It seems to skip id_dsa, but doesn't even try id_rsa. Can anyone help? This is tiresome.
