SOLVED Internal Server Error loading WHM after update

[netwanderer]

Good afternoon,
I've been updating my cpanel install from a very old V60.

the last successful login was at version 68.
loading /whm is currently giving:
Internal Server Error
500

Undefined subroutine &Cpanel::Config::Session::session_dirs called at /usr/local/cpanel/Cpanel/Session/SinglePurge.pm line 73.


Running the only thing I have seen on the forum searching I ran the following and had this response.


[email protected] [~]# exim -bpc
11
[email protected] [~]# ps faux |grep upcp
root 32244 0.0 0.4 62780 15700 ? Ss 13:36 0:00 cPanel Update (upcp) - Slave
root 15704 0.0 0.0 118040 1004 pts/0 S+ 16:18 0:00 \_ grep upcp

Can someone out there tell me where to go from here to continue patching/upgrading.

The presence of the upcp process would indicate that an update process is still running. Is that still there and is it still a problem?

indeed, seems it waited till server load dropped a touch and kicked off the next one along.
I had not realised that it would daisy chain the updates.
Guess I just freaked when I couldn't login.

Hello @netwanderer,

I'm happy to see the issue was solved after the update process finished.

I had not realised that it would daisy chain the updates.

Yes, if you start a cPanel update that includes multiple major version upgrades of cPanel & WHM (e.g. version 60 to version 80), the cPanel & WHM update process (upcp) will automatically upgrade your server to each intermediate version. One of the reasons it's done this way is so the update process can perform compatibility checks for each intermediate version prior to the upgrade to that version.

Thank you.
