That's great, thanks Mate.
I have a site here
https://www.price.ro/rezultate~acer-nitro-5-an-515.html
... and I am wondering if yours is one of those listed?
I am particularly interested in the "detalii produs" as to whether yours has
RAM - 8GB or 16GB
HDD - hard drive - 1TB
SSD - solid state drive - 256GB or 512GB
Does it have just the one drive or two?
For example, my Dell Inspiron laptop has a 256GB SSD
and a 2TB 5400rpm HDD.
See how you go with that.
Do you have Windows 10 installed on that machine? Do you wish to keep it?
Where i am leading here is that I find it curious that the store, or Acer, would put Linpus on this machine.
There is next to no support for LInpus in the community. It is 10 years old, and not even "proper Linux" - it is licensed through Acer and does not have all the elements of FOSS (Free and Open Source Software).
DistroWatch have this about it
https://distrowatch.com/table.php?distribution=linpus
... and its status is "Dormant" as in asleep, so even contacting Linpus themselves may not help.
Depending on what you come back to us with, I would be inclined to put on a different Linux in place of Linpus.
Cheers
Wizard
