Level 10 Debug Log
I figured out, what causes the problem: The libtevent package is incompatible. F25 ships libtevent-0.9.30-1.fc25.x86_64. I downloaded the libtevent-0.9.28-1.fc24.x86_64 from the F24 repo and downgraded it using "dnf". Now Samba starts correctly. Can you please ship an older version of libtevent in F25 or fix whatever causes this incompatibility? Thanks. Same here, downgrading libtevent helped. *** This bug has been marked as a duplicate of bug 1375973 *** |
