[Bug 1952094] Re: CIFS mount error: iocharset utf8 not found
@ayanamist - I don't know what to do at this point. Its clearly not a kernel issue. As such, I'm marking the kernel bug invalid. ** Changed in: linux (Ubuntu Focal) Status: In Progress => Invalid -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1952094 Title: CIFS mount error: iocharset utf8 not found To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1952094/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

[Bug 1952094] Re: CIFS mount error: iocharset utf8 not found
@ayanamist - I am somewhat baffled. Upstream does not think the patch I reverted is the root cause, so lets get back to basics and ensure this isn't something local to your system. This kernel is vanilla 5.4.0-90.101, but built by me. If this fails then I think we're going to have to do a full bisect.
