Yes, it is, and was right after my desktop Ubuntu installation. I replaced the 9.10 with with the one I took from 9.04.
To be true, I begin to think there was something within my database directory /home/database (into which my.cnf pointed to) that prevented normal installation and running, although the only difference was debian flag file. In my directory it had 5.0 in name (debian-5.0.flag), while in the database folder created after using default my.cnf the file had 5.1 (debian-5.1.flag). Since mysql-common is installed as a requirement to ubuntu-desktop, I had some problems with locating the source of problems. But after this adventure I moved all my database servers from desktop system to virtual machine with ubuntu server. -- package mysql-server-5.1 5.1.31-1ubuntu2 failed to install/upgrade: el subproceso post-installation script devolvió el código de salida de error 127 https://bugs.launchpad.net/bugs/370000 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
