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. root@mainserver [~]# exim -bpc 11 root@mainserver [~]# 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
