Hi Marco, In my opinion, I think we should install rsyslog above on the container. You could create a new image for ubuntu 18.04 for never do it again.
Like what I said, could be it happened on the image of Proxmox, so you should install the newest package of rsyslog on the container. By default, Ubuntu 18.04 rsyslogd version is rsyslogd 8.32.0. This is a result after upgrade: $ rsyslogd -version rsyslogd 8.40.0, compiled with: PLATFORM: x86_64-pc-linux-gnu PLATFORM (lsb_release -d): FEATURE_REGEXP: Yes GSSAPI Kerberos 5 support: No FEATURE_DEBUG (debug build, slow code): No 32bit Atomic operations supported: Yes 64bit Atomic operations supported: Yes memory allocator: system default Runtime Instrumentation (slow code): No uuid support: Yes systemd support: Yes Number of Bits in RainerScript integers: 64 See https://www.rsyslog.com for more information. -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to logrotate in Ubuntu. https://bugs.launchpad.net/bugs/1801910 Title: logrotate fails on LXC Status in logrotate package in Ubuntu: Confirmed Bug description: daily, I receive this alert from logrotate script in cron.daily: /etc/cron.daily/logrotate: Failed to kill unit rsyslog.service: Input/output error error: error running non-shared postrotate script for /var/log/syslog of '/var/log/syslog ' run-parts: /etc/cron.daily/logrotate exited with return code 1 My ubuntu is a LXC running on top of ProxmoxVE. the problem occour when logrotate script call /usr/lib/rsyslog /rsyslog-rotate that has this call: systemctl kill -s HUP rsyslog.service I already checked my disks status (because the input/output error) but them are ok.
