Still having the write error to /etc/backuppc. Providing this summary to help others.
I reinstalled Apache2 and backuppc. Permissions are definitely OK. Apache2 running as www-data, user www-data is in group www-data, and permissions in /etc/backuppc are writeable for backuppc:www-data This previous thread had the same problem: https://sourceforge.net/p/backuppc/mailman/backuppc-users/thread/[email protected]/ One commenter (not the thread initiator) said his distro had SELinux running and had to write a policy to allow it to run. I don't have SELinux running. The thread initiator did not get his problem solved but mentioned something in the end about the file system being read only. His was not, and neither is mine. I found this discussion: https://github.com/backuppc/backuppc/issues/188 which had the same issue. One respondent provided some code to add to /usr/share/backuppc/lib/BackupPC/Storage/Text.pm to get more info on the error. I did this and got the same additional error information: --- TextFileWrite: Failed to write /etc/backuppc/localhost.pl.new (errno = Read-only file system, uids = 33,113, gids = 33 33,33 33, umask = 027, ver = v5.40.1, prog = /usr/bin/perl) --- I also got the read-only file system message, which didn't make sense (note uid and gid 33 are both www-data and uid 113 is backuppc). So then I found this thread with the same issue: https://www.reddit.com/r/sysadmin/comments/104960e/backuppc_turning_linux_client_into_a_readonly/ That user turned out to have a bad sector on his disk. So I plugged in an external drive with a fresh ext4 partition. Did a temporary mount and copied over the contents of /etc/backuppc, then remounted it at /etc/backuppc. And it worked! So I must have some bad blocks where /etc/backuppc was in the original installation. So I am going to run some smartmon or fsck/badblocks tests and the drive, and reinstall ubuntu.
