When trying to connect to sftp server, this message appears:

sftp: unknown host key type: 1835008

and then (in Russian):

Не удалось перейти в "/sftp://***@***/"
Операция для сокета применена к не-сокету (88)

In official Ubuntu repo there is no such error. Dolphin and Krusader are connecting without problems too.

Version 4.8.28-139-gf98cda9ff from git.

Replying to m_ok (#4414):

When trying to connect to sftp server, this message appears:

sftp: unknown host key type: 1835008

1835008 is 0x1C000, a ED25519 Key. This was added in libssh2-1.9.0.

In official Ubuntu repo there is no such error.

I'm not Ubuntu user and don't have any idea what is the mc version in that repo.

• Milestone Future Releases deleted
• Status changed from new to closed
• Resolution set to invalid

Pleas build mc with latest libssh2. Maybe in Ubuntu you still have the version that doesn't do proper host key checking.
