The lochac.sca.org server currently runs Ubuntu Linux 16.04. Maintenance releases for this version will cease in April 2021. Masonry will therefore intends to upgrade the sever to Ubuntu 20.04 in two phases:
- Ubuntu 16.04 to 18.04 on Monday 7 December 2020; then
- Ubuntu 18.04 to 20.04 on Monday 14 December 2020.
The main effects of the upgrade will be to back-end software that is not visible to ordinary users, such as bug-fixes, security updates, performance improvements, and so on. The webmail system, however, will be changed from the current interface (Squirrelmail) to a more modern one (Roundcube), and mailing list administrators will have the option to move from the current Mailman2 installation to the more modern and featureful Mailman3.
All services should continue to operate as normal throughout the upgrade, except for a few re-starts on the dates above. Each re-start should take no more then fifteen minutes.
