git with IntelliJ IDEA: Could not read from remote repository
git, intellij-idea
Solution
IntelliJ's built-in SSH client seems to hash its `known_hosts`, but the one I had had its host names in clear text.
When I deleted the file and let IntelliJ create a new one, with only my (hashed) GitLab server and nothing else, it worked.
It's also not possible to mix it - keep some unhashed entries together with hashed entries for IntelliJ. So, you have to configure your other SSH clients to use hashed hosts.
Problem
Since a few weeks, I'm not able to pull or push from or to the remote repository. I thought it happend when upgrading to IntelliJ IDEA 14, but I can reproduce the problem with IDEA 13.1.5 as well. The tooltip says "Fetch failed fatal: Could not read from remote repository." and the exception in the Version Control tab reads ``` 14:02:37.737: cd C:\dev\project 14:02:37.737: git -c core.quotepath=false fetch origin --progress --prune java.io.IOException: Padding in RSA public key! at com.trilead.ssh2.signature.RSASHA1Verify.decodeSSHRSAPublicKey(RSASHA1Verify.java:37) at com.trilead.ssh2.KnownHosts.addHostkey(KnownHosts.java:98) at com.trilead.ssh2.KnownHosts.initialize(KnownHosts.java:414) at com.trilead.ssh2.KnownHosts.initialize(KnownHosts.java:440) at com.trilead.ssh2.KnownHosts.addHostkeys(KnownHosts.java:137) at org.jetbrains.git4idea.ssh.SSHMain.configureKnownHosts(SSHMain.java:462) at org.jetbrains.git4idea.ssh.SSHMain.start(SSHMain.java:155) at org.jetbrains.git4idea.ssh.SSHMain.main(SSHMain.java:137) fatal: Could not read from remote repository. Please make sure you have the correct access rights and the repository exists. ``` Using the built-in terminal of IntelliJ, executing `git -c core.quotepath=false fetch origin --progress --prune`, it works just as it should. According to the stacktrace, there seems to be a problem with my `KnownHosts`, so I deleted our git server from `~/.ssh/known_hosts`, hoping IntelliJ would insert it again. But the problem still appears when updating via the UI, and there is no new entry written in `known_hosts`; thinking about some caching of the file, I restarted IntelliJ, without success. When doing another `git fetch` from the terminal, now I'm getting asked if I want to permanently add the server. After that, it has been written to `known_hosts` again, but IntelliJ still won't let me update my project. I haven't found anything about this behavior online, so I guess it's not a known bug with the new IntelliJ version. Nevertheless, I updated to 14.0.2, but the problem still exists. IntelliJ is configured to use the built-in SSH executable. Does anybody have a clue what could be the problem here?
