Hi,
I had a bitcoin wallet with a few coins in it which I installed in my previous Ubuntu 16.04, in 2017.
I didn't use it very much but it was working.
Recently I upgraded (reinstalled) my Ubuntu version to 18.04.02. During the installation a new partition was created, including all my personal files which includes also the bitcoin files. All the bitcoin files are there (the wallet.dat and bitcoin-qt, blocks, etc.) but I can't start the wallet anymore.
Do I need to deinstall the wallet and reinstall it? If so, am I going to lose the coins I had?
And in case I do need to reinstall, how can I do it?
Many thanks in advance...
Your bitcoin core client might point to the new partition, but your wallet.dat is still on the old one.
If the file is still there, then most probably you would need to move the wallet.dat file manually to the new partition.
Your old wallet.dat is in home/username/.bitcoin/wallets
Make sure you backup both wallet files to a USB stick beforehand just in case you mix them up
also make sure the bitcoin core (qt) is closed before you exchange the wallet.dat files
after you put it there, it will take some time to re-sync
