ROSA Desktop Fresh R4 uses repositories different from the ones of Fresh R1/R2/R3, so your R3 system will not be updated automatically to R4 by means of usual updates. In order to perform such distribution upgrade, one should do the following steps:

  • update the system to the latest R3 state:
# urpmi --auto-update

(in order to guarantee that we have the latest versions of all packages; update from Fresh R1 or R2 to R4 directly is theoretically possible, but we didn't test this scenario thoroughly).

  • remove all Fresh R3 repositories. If you don't have any repositories except official ROSA Desktop Fresh R3 ones, then you can simply remove all software sources:
# urpmi.removemedia -a
  • add release repositories of Fresh R4:
    • for 32bit systems:
# urpmi.addmedia --distrib http://mirror.rosalab.ru/rosa/rosa2014.1/repository/i586/
# urpmi.update --ignore updates
    • for 64bit systems:
# urpmi.addmedia --distrib http://mirror.rosalab.ru/rosa/rosa2014.1/repository/x86_64/
# urpmi.addmedia main32_release http://mirror.rosalab.ru/rosa/rosa2014.1/repository/i586/main/release
# urpmi.addmedia main32_updates http://mirror.rosalab.ru/rosa/rosa2014.1/repository/i586/main/updates
# urpmi.update --ignore updates

(32bit main/release and main/updates repositories are necessary in 64bit systems in order to make 32bit-only applications such as Skype available).

  • update all packages to R4 state; preliminary download all necessary packages (the latter is important, since the network connection can go down during update):
# urpmi --no-install --auto-update --auto
# urpmi --auto-update --auto

Note that depending on Internet connection speed and number of packages installed in the system, the update time may vary significantly. Average update time is about several hours. In some very special cases update can take about a day or even more.

  • Turn back repositories with R4 updates and update your system to be sure that it is up to date:
# urpmi.update --no-ignore updates
# urpmi --auto-update --auto
