I tried to sync my old computer which is running Solus Budgie and have not been updated for one month.
I came across this error message.
I waited for 10 minutes and my keyboard and mouse crashed. I couldn't do anything.
i have no choice but to do a reset, and/or hard reboot
After reboot :
[FAILED] Failed to start lightdm.service - Light Display Manager
I'm at a loss at what to do now.
I lost my 2 desktops today, after performing the same sync.
Desktop 1 : synced, rebooted, stuck as "ASRock" logo, crashes at BIOS.
Desktop 2 : synced one month's worth of packages, 329 packages, 2.2GB, stuck at "Updated clr-boot-manager ... running" wait for 10 mins and crashed, reboot and it shows [FAILED] Failed to start lightdm.service - Light Display Manager
If anyone can help me, please contact me on Matrix support channel. I'm there today.
Thank you very much.
UPDATE
Reilly Brogan assisted me over the course of 2 hours on Matrix and resolved my issue.
I am thankful for his help.
Both my desktops are running fine now.
