Qeustion about updating

Because of some renovations in our home i’m not able to use my PC for a view weeks.

Will there be issues when i’ll try to update in a few weeks?

Should be fine, as long as it isn’t months

I’m out of home for 4-5 weeks and there is no problem with updates.

I concur with previous posters. I’ll also suggest to have a Live usb with CachyOS ISO in case something go wrong and you will need to perform some rescue operations. Hopefully you won’t need to but just in case.
